Astronaut Mike Foale KB5UAC Leaves NASA
by Clint Bradford 09 Aug '13

09 Aug '13

Astronaut Michael Foale Leaves NASA After 26-year Career NASA astronaut Michael Foale has retired, ending a 26-year space agency career that included 375 days in space during six space shuttle missions and extended stays aboard two space stations. Foale spent 145 days aboard the Russian space station Mir in 1997 and 194 days aboard the International Space Station as commander of Expedition 8 from October 2003 to April 2004. He also conducted four spacewalks over his NASA career totaling almost 23 hours. "We salute Mike and his contributions to NASA as an accomplished member of the astronaut corps," said NASA Administrator Charles Bolden. "Starting with his first flight, shuttle mission STS-45, when we flew together in 1992, Mike has worked tirelessly to support NASA's quest to explore the unknown. I know Mike will go on to do more great things as he continues to support the aerospace industry in his new endeavor." Foale held many positions during his NASA career, including chief of the Astronaut Office Expedition Corps, assistant director (technical) of the agency's Johnson Space Center in Houston, and deputy associate administrator for exploration operations at NASA Headquarters in Washington. He most recently worked in support of Soyuz and International Space Station operations, as well as space station spacewalk activity and spacesuit development. Foale's future plans include advancing green aviation technology.

Re: magnetic reed switches f(not really needed)
by Robert Bruninga 09 Aug '13

These motors run at a nearly constant rate. ALl you have to do to know position is to keep track of the time they are on. It remains calibated because at the end of every pass (it ends at zero elevation) so you konw you are at 0 (include say a 10% overshoot after the pass to be sure it is at 0). Same for Azimuth. Each time you find yourself within 45 degrees of the mechanical stop at south (or north), after the pass, send the rotator to the stop with again, 10% overshoot, this re-establishes that reference. So, no feedback needed (for the beamwidths of VHF and UHF anyway). Oh, and you dont need elevation at all really for all LEO satellites.

magnetic reed switches for indication
by Robert C. Campbell 09 Aug '13

09 Aug '13

I am using reed switches for both my AZ and EL visual feed back on my newest build. I have had to slow the motors down with a PWM so that the reeds don't skip a count. Both AZ and EL are still within the speed of keeping up with ISS. You can determine the ratio of motor turns to one revolution of the AZ full 360 or 90/180 for the EL and use that ratio to determine the position in degrees. Repeat-ability seems very good. If you are going visual/manual positioning you can check on utube or instructables.com and find a easy build for a modified $ 2.00 Dollar General calculator that then becomes a pulse counter by simply connecting the enter button to your reed and entering the ratio and pressing the plus sign. Then each rotation the calculator will tell you the degrees the antenna is looking at. Yes, it does need reset after each pass, and yes, if you run by the bird and go back the calculator will give you some extra counts since it is counting reed switch contacts not true degrees of indication. Purchase 5 of them, one for practice, 2 for EL and 2 for AL then if you start from the same standard position each time one can add and one can subtract. This should work fine assuming that the driver maintains mental focus. It is a small fun project and cheaper then happy hour at the local pub. The Pulse Width Modulator works good with this because you can adjust the speed of the motors to keep up with the bird. This of course assumes you are working with direct current motors. Bob

Non-mechanical Azimuth/Elevation Feedback Advice
by Zach Leffke 09 Aug '13

09 Aug '13

Hello Everyone, I recently came into possession of a Pelco PT170-24P tracking pan tilt pedestal designed to support large security cameras. My intent with this new acquisition is to repurpose it as a "low cost" (got it on Ebay for ~$75 + S&H) alternative for an antenna tracking pedestal for amateur satellites. It uses 24VAC induction motors to move the azimuth and elevation assemblies, pretty much just like the G5500s that I'm sure so many of us are familiar with. It definitely cannot support the same amount of weight as the G5500, but I'm looking to construct a small, portable satellite ground station node and this thing is plenty beefy enough to handle a couple of Arrow style antennas. Here is the problem, it provides absolutely no feedback. My question to the group is does anyone know of a non-mechanical method for getting relatively accurate feedback for azimuth and elevation. I'm looking for an all electronic means that I can mount somewhere outside of the actual pedestal assembly (like perhaps on the cross-boom) that will be able to provide measurement of the az/el (or pan/tilt, or yaw/pitch, whatever you want to call it) position. I'm using an arduino microcontroller for the tracking controller. Originally I intended to find a way to mount potentiometers in inside the unit and simply use the ADCs on the arduino to read the position feedback voltage from the pots, however, there is barely enough space to mount an elevation feedback pot inside the unit, and there is virtually no space for an azimuth feedback pot. Hence I'm looking for a non-mechanical method. My first thoughts for the elevation feedback was to use the old potentiometer plus nice heavy weight method mounted out on the boom. This idea doesn't appeal to me very much as other factors can now affect the position feedback (such as high winds). I then thought of something along the lines of an accelerometer. I also tossed around the idea of a 2-axis gyro for both Az/El. My issue is I have limited experience working with these types of sensors, and was hoping to get advice from everyone in this group. I know for example that the gyro will provide rate of motion around an axis and thus I have to integrate over time to get the actual position. This becomes cumbersome because now I have to keep track of time in the Arduino while executing movement commands (certainly do-able, just more complicated than reading an ADC voltage). Additionally, I believe these devices suffer from drift and require frequent calibration (although there may be a scheme of starting from a known position, say at one of the limit switch contact points, for each pass that might work). I also toyed with the idea of an electric compass for azimuth feedback, but I'm worried about distortion of the magnetic field near the pedestal due to the AC induction motors or when the antennas are radiating. In theory the motors are housed inside the metal pedestal enclosure and thus are shielded from the outside world, but I can just see it now, nice steady feedback when the pedestal is stopped and as soon as I execute a motion command the azimuth feedback starts dancing all over the place. Since the motion stop command is based on achieving the target position, system instability is sure to occur. Even if I solve the AC motor EMI problem, I still worry that when transmitting the fields could potentially be distorted if near the antenna (remember my goal is a compact design) and taint the position feedback. Any ideas from the group would be greatly appreciated. I'm looking for a "sparkfun" type solution here and if anyone has experience working with accelerometers, gyros, electric compasses, etc. I would love your advice on which might be the way to go for the position feedback. If you think I've hit on a good idea above and should go with it please let me know. Again I'm using an Arduino, so analog voltage feedback, I2C, SPI, and UART serial are all on the table for communicating with the sensors to get the feedback info. Thanks in advance! Sincerely, Zach, KJ4QLP

Thanks for the mail via AMSAT.org My name is David Bowman G0MRF and I'm a member of the team building FUNcube, due for launch this November. I can help with transponder design, but there are some points which you need to consider. 1) The use of V band for the uplink will be a poor choice for your location. The interference from China and other countries on 145MHz will mean the transponder will not be usable. Using U band for the uplink is a much better choice. 2) The 100kHz bandwidth is too much for the typical power available from a CubeSat. If you get your RF team to do a link budget analysis, you will see the cubesat power budget will not support 100kHz of bandwidth. Ususally 30kHz is as much as you can do with a 1U cube. 3) You may want to consider a FM 'repeater' as there is now only 1 in orbit, while there are several linear transponder satellites ready to be launched. The FM design will allow you to run a very efficient power amplifier (70%) and power can be saved over oceans and areas of low population by using a 67Hz access tone (CML FX465) I can assist with design but would need to know if you are planning a 1U 2U or 3U design.

Re: Non-mechanical Azimuth/Elevation Feedback Advice
by Zach Leffke 08 Aug '13

All, Thanks to everyone that has responded both on and off list. For my first attempt at finding a non-mechanical solution I plan to use the MEMS accelerometer (for El) and magnetometer (for Az) solution. When still exploring the Potentiometer solution, because of space requirements and other factors I was pricing out multi turn potentiometers. For the gearing ratios I needed, I required about a 5 turn potentiometer, which at least according to digikey and the quick search I did, priced to about $20.00 apiece. The MEMS Magnetometer (HMC5883L) and Accelerometer (MMA8452Q) each price out to less than $20.00 each on sparkfun, so I'll actually be saving a few bucks. That's the plan, at least for the first iteration. We'll see how it goes! Thanks again to everyone! Go Team AMSAT! -Zach, KJ4QLP

I'm also thinking about an el cheapo rotator based on a pan/tilt base. (In fact search el cheapo rotator for an article about doing the same thing manually). The pan/tilt that I was going to start with does have a "center" command as well as 4 memories where you can remember previous positions. It is based on steppers, not A/C, though. Anyway, I was thinking about programming 4 strategic positions into the memories and using them with "center" to get close to where I want to be, and then send step commands to get more exact. Requires some programming of course, but that's what Arduinos are for! I *like* the MEMS compass idea. Pretty cool! Burns Fisher, W2BFJ

ARRL Article on AO7
by k4feg 08 Aug '13

08 Aug '13

Hello Satellite Lovers!! Well it is nice to see that I have risen to the level of being "quoted" by the ARRL, they got most of the stuff essentially correct but did not get it completely right: /*What we know for certain about AO7:*/ 1) there are ZERO batteries working! 2) it only works when it has enough solar power generated to make it operational. 3) it was only in Eclipse for periods of a maximum of 15 minutes during each orbit and only during the period I refer to as the "Eclipse Cycle" which occurs at the same approximate time each year for about 9 weeks. My additional conversations with Jan A. King, W3GEY, have provided me with additional information about the design and I have found it most intriguing. I have considered writing a more detailed paper centered around my conversations with Jan, and my personal observations of the operations. / //I just am not sure if anyone is particularly interested in such a detailed account of AO7's current state of operation./ Many of you have read my running accounts of AO7 operations this year since the Eclipse Cycle began and subsequently ended. Many of you have provided excellent insight as to why the Doppler shift varies as much as it does after these Eclipse Periods and also the theories as to why the distortion levels occur on some satellite passes and not others. Thank you all that have contributed to the debate and the study. I Hope I have not bored everyone with my posts about AO7, simply the most successful satellite ever launched! /*73 ALL FRM*//* *//*STARCOM DIV GGG*//* *//*K4FEG*//* *//*GGHQ: Em55aj84ta*//**/ /...no grid left behind.../

Clint, K6LCS, I would normally not ever reply to anyone else's responses to BB postings but I could not let this one go. I believe that you owe Mineo a very sincere apology for your scathing response to his satellites list. I'm sure that you feel that your information is better for the newer satellite operators, and while that may be true, I found Mineo's posting very informative. Not only that, the one thing that you were criticizing the list for is there, but you apparently didn't see it for yourself. If you look at the very last column it clearly states Active with an * by each one that has that status. Both the .xls & .html versions have this column, so what information that you thought would be the most helpful IS on the list. I'm sorry if you are offended by someone 'calling you out' on the BB, but this is one time I just couldn't sit idly by. If you feel the need to respond, you can do it here on the BB or personally at 'my call'@comcast.net Sincerely, Jeff Lamb, NX9B, EM66sj61pe 73!

This compilation reflects an awful lot of work - and you are to be complimented for creating it. But it troubles me: When I was new to the amateur satellites seven or eight years ago, it was this kind of list that frustrated me, because it is, for the most part, absolutely worthless to anyone wanting to work the currently available amateur satellites. Your work is a reflection of history. And is important. But I wish it had a preface of some sort, telling viewers that is is a historical document, and to point readers who are looking for CURRENT satellite information to appropriate sources of information. It was after programming MANY satellites I found during Internet searches that I later found out were LONG DEAD that I created my meager Web site, catering to those who wanted to work the FM birds "this week" with minimal equipment. Again - your compilation is a valuable, historical document. Thank you for your work.

AO7 switch?
by k4feg 06 Aug '13

06 Aug '13

Well I am definitely going to try and make the "wee hours of the morning" pass of AO7, to see what Mode it is in. AO7-a was loud and sometimes distorted, but it was weak at others. I am uncertain of the switch time at this moment but it should be easy enough to nail it down once the satellite has settled in to a better illumination angle with the sun. I for one will be happy to have the "Old Girl" back into her familiar operational mode of switching every day and having clean audio from the satellite. If anyone has some current information as to when the mode switch is, I would be interested in knowing when that time is! 73 All FRM K4FEG

good news! I will be using my IC910 with arrow. I will be in CN77 late on 8/5 through 8/7. My earlier priority of XYL, grand daughter, dogs, then ham radio still holds. (pending delicate negotiations). This will open up the linear sats. Here you are Drew!. I am not sure of email (internet) however I do have Franks (K4FEG) cell phone and he can advise those interested via the bb. If I can get down to CN76 remains to be seen. It is just a speck of a grid square. Linear birds- I will maintain my tx frequency and if too busy (qrm) will listen +/- to speed up Q's. 73 Bob W7LRD soon to be CN77

I will be in CN77 (on the beach) from late on 8/5 till 8/7. So armed with a IC-W32A and a arrow, I will attempt to hand out that grid square on SO-50. The priorities will be XYL, grand daughter, dogs, ham radio. Probably in that order, I'm sure you understand. I will be testing my stuff this afternoon from home, CN87. 73 Bob W7LRD Seattle

04 Aug '13

AMSAT NEWS SERVICE ANS-216 The AMSAT News Service bulletins are a free, weekly news and infor- mation service of AMSAT North America, The Radio Amateur Satellite Corporation. ANS publishes news related to Amateur Radio in Space including reports on the activities of a worldwide group of Amateur Radio operators who share an active interest in designing, building, launching and communicating through analog and digital Amateur Radio satellites. The news feed on http://www.amsat.org publishes news of Amateur Radio in Space as soon as our volunteers can post it. Please send any amateur satellite news or reports to: ans-editor at amsat.org. In this edition: * HamTV Transmitter Launched to ISS * AMSAT.ORG Gets Make Over * Have You Received Your 2013 AMSAT-NA Board of Directors Ballot? * AMSAT Mentions and Articles of interest in the Press * Radio Scouting – ARISS Contact Reception Report * Radio Ham’s Leaky Spacesuit * Curiosity First Anniversary Event * ARISS News * Satellite Shorts From All Over SB SAT @ AMSAT $ANS-216.01 ANS-216 AMSAT News Service Weekly Bulletins AMSAT News Service Bulletin 216.01 >From AMSAT HQ SILVER SPRING, MD. DATE August 4, 2013 To All RADIO AMATEURS BID: $ANS-216.01 HamTV Transmitter Launched to ISS On Saturday, August 3 at 1948 UT the Japanese HTV-4 cargo vessel was successfully launched to the International Space Station (ISS). On- board was the HamTV transmitter and a number of CubeSats carrying amateur radio payloads. The Japanese space agency JAXA has announced details of four CubeSats on the launch. They will be deployed from the ISS by the JEM Small Satellite Orbital Deployer (J-SSOD) between October 2013 and March 2014. The four CubeSats are: • PicoDragon a 1U CubeSat developed by Vietnam National Satellite Center(VNSC), University of Tokyo, IHI aerospace. CW beacon on 437.250 MHz and 1k2 AFSK AX.25 telemetry on 437.365 MHz • ArduSat-1 and ArduSat-X 1U CubeSats developed by Nanorack, NanoSatisfi. ArduSat-1 437.325 MHz 9k6 MSK CCSDS downlink. ArduSat-X 437.345MHz 9k6 MSK CCSDS downlink. • TechEdSat-3 a 3U CubeSat developed by NASA Ames Research Center The company NanoRack has announced it is sending 36 Units of CubeSats to the ISS (believed to be 26 separate CubeSats, some 2U or 3U in size). At the time of writing it is believed they will be going on a later cargo vessel. The main mission of HamTV is to perform contacts between the astronauts on the ISS and school students, not only by voice, but also by unidirectional video from the ISS to the ground within the ARISS program. The ESA Columbus module on the ISS will host the 2.4 GHz video transmitting station in addition to the existing 144 MHz FM amateur radio station. This new equipment can broadcast images from the ISS during the school contacts or other pre-recorded video images up to 24 hours a day to allow ground stations tuning. It is planned to transmit DVB-S signals on 2.4 GHz at either 1.3Msps or 2.3Msps with 10 watts of RF. The IARU Amateur Satellite Frequency Coordination Panel have announced frequencies of 2422.0 MHz and 2437.0 MHz. HamVideo is the name of the onboard DATV S-band transmitter. HamTV is the name of the complete system, comprising DATV downlink and VHF voice uplink. Kaiser Italia SRL was the prime-contractor for the design and development of the flight and ground segment http://www.kayser.it/index.php/exploration-2/ham-tv Read the HamTV overview paper here.

Note that Grove Enterprises has announced that it will cease publication of Monitoring Times in December of this year. [ANS thanks ANS Editors for the above information] --------------------------------------------------------------------- Radio Scouting – ARISS Contact Reception Report The Boy Scout’s of America 2013 Jamboree included many radio activities by the club station K2BSA. The station was on the air on various frequencies and modes of operation and had a planned contact with astronauts aboard the international space station as part of the Amateur Radio on the International Space Station (ARISS) program. ARISS contacts are important opportunities for students to learn about amateur radio, space exploration, science and technology. They also offer radio hobbyists a unique opportunity to monitor communications from the most impressive human-built structure ever sent into a Low Earth Orbit (LEO). Participating in “Radio Scouting,” the general term used to describe the activities associated with amateur radio and scouting, also affords scouts the opportunity to earn their radio merit badges. The space station was making a relatively low 30 degree pass to the south of my location. I copied amateur radio station NA1SS’s half of the contact by climbing to the peak of my roof to get as free from the trees and other rooftops as possible and used my Yaesu FT-60R handheld transceiver and my “Slapshot” antenna. The following is my official reception report: Date: July 20, 2013 Time: 15:34 to 15:38 UTC Frequency: 145.800 +/- Doppler shift Mode: FM Signal: Full quieting Comments: I copied NA1SS making contact with K2BSA and begin answering questions. It sounded like Italian astronaut Luca Parmitano, KF5KDP was conducting the QSO. Parmitano answered questions about whether he was a scout, how they clean up after themselves, and the use of robotics in space. I copied two audio clips, the first and clearest clip is 3 minutes long. Fortunately my clip contains the audio with both call signs being used by Parmitano. See the full article with links to the audio at http://tinyurl.com/ANS-216-B (Flash player required) [ANS thanks Christopher VE4CWF for the above information] --------------------------------------------------------------------- Radio Ham’s Leaky Spacesuit In edition 683 of Jonathan’s Space Report (JSR) Jonathan McDowell provides the history of the spacesuit of radio amateur Luca Parmitano KF5KDP which developed a water leak inside the helmet during a spacewalk on July 9, 2013. The spacewalk was abandoned and he was assisted back to the International Space Station (ISS) by Chris Cassidy KF5KDR. The suit Luca Parmitano KF5KDP used for the extravehicular activity (EVA) was EMU 3011. It had three previous station tours, here is its flight history: Flight 1 STS-79 1996 Sep 16-1996 Sep 25 (Apt, not used) Flight 2 STS-83 1997 Apr 4-1997 Apr 8 (Spacelab, Gernhardt, not used) Flight 3 STS-94 1997 Jul 1-1997 Jul 17 (Spacelab, Gernhardt, not used) Flight 4 STS-91 1998 Jun 2-1998 Jun 12 (Chang, not used) Flight 5 STS-95 1998 Oct 29-1998 Nov 7 (Robinson, not used) Flight 6 STS-96 1999 May 27-1999 Jun 6 (Barry, 1 EVA) Flight 7 STS-101 2000 May 19-2000 May 29 (Horowitz, not used) Flight 8 STS-106 2000 Sep 8-2000 Sep 20 (Backup, not used) Flight 9 STS-97 2000 Dec 1-2000 Dec 11 (Tanner, 3 EVA) Flight 10 STS-100 2001 Apr 19-2001 Jul 25 (ISS tour, Hadfield (2), down on 104) Flight 11 STS-109 2002 Mar 1-2002 Mar 12 (HST, Massimino(2)) Flight 12 STS-111 2002 Jun 5-2005 Aug 9 (ISS tour, Sellers (3),Pettit(2), down on 114) Flight 13 STS-126 2008 Nov 15-2009 Nov 27 (ISS tour, down on 129, not used) Flight 14 STS-132 2010 May 14-present (ISS tour; Williams (1), Hoshide (2), Parmitano(2)) EMU 3011 incorporates the PLSS 1011 backpack – this contains most of the systems and you can think of it as the core of the suit considered as its own spaceship, with the other components as a relatively inert bubble containing the human occupant. Before the EMU 3000 series nomenclature was adopted, PLSS 1011 flew multiple times: Flight 1 STS 61-B 1985 Nov 27-1985 Dec 3 EMU 1070/PLSS 1011 (Spring, 1 EVA) Flight 2 STS-26R 1988 Sep 29-1988 Oct 3 EMU 1090/PLSS 1011 (Lounge, not used) Flight 3 STS-27R 1988 Dec 2-1988 Dec 6 EMU 1090/PLSS 1011 (Ross, not used) Flight 4 STS-29R 1989 Mar 13-1989 Mar 18 EMU 1090/PLSS 1011 (Springer, not used) Flight 5 STS-28R 1989 Aug 8-1989 Aug 13 EMU 1098/PLSS 1011 (Brown, not used) Flight 6 STS-36 1990 Feb 28-1990 Mar 4 EMU 2008/PLSS 1011 (Thout, not used) Flight 7 STS-41 1990 Oct 6-1990 Oct 10 EMU 2008/PLSS 1011 (Akers, not used) Flight 8 STS-39 1991 Apr 28-1991 May 6 EMU 2008/PLSS 1011 (Harbaugh, not used) Flight 9 STS-48 1991 Sep 12-1991 Sep 18 EMU 2008/PLSS 1011 (Buchli, not used) Flight 10 STS-46 1992 Jul 31-1992 Aug 8 EMU 2021/PLSS 1011 (Chang, not used) Flight 11 STS-73 1995 Oct 20-1995 Nov 5 EMU 2034/PLSS 1011 (Coleman, not used) So, this PLSS has flown a total of 25 times in space over 28 years – although of course there’s a bit of a “grandfather’s axe” paradox involved as it’s not clear how many of the original components remain. The article includes a video of NASA astronaut Chris Cassidy KF5KDR showing where the water leaked.

The event will be broadcast on NASA Television and streamed live on the agency's website. Media and the public are welcome to attend to hear highlights from the Mars Science Laboratory's first year of investigations, learn about upcoming NASA robotic missions to the red planet, and speak with astronauts conducting experiments in space that will enable human exploration of Mars in the 2030s. Those interested in attending should plan to arrive at NASA Headquarters, 300 E St. SW, by 11:30 a.m. Seating is limited. Participating will be: • Charles Bolden, NASA administrator • Chris Cassidy, KF5KDR and Karen Nyberg, NASA astronauts, live from the space station • Jim Green, director, Planetary Division, NASA's Science Mission Directorate • Sam Scimemi, director, NASA's International Space Station Program • Prasun Desai, acting director, Strategic Integration, NASA's Space Technology Mission Directorate The Mars Science Laboratory mission successfully placed the one-ton Curiosity rover on the surface of Mars on Aug. 6, 2012, UTC and EDT (evening of Aug. 5, 2012, PDT), about 1 mile from the center of its 12-mile-long target area. Within the first eight months of a planned 23-months primary mission, Curiosity met its major science objective of finding evidence of a past environment well-suited to support microbial life. With much more science to come, Curiosity's wheels continue to blaze a trail for human footprints on Mars.

The contact began 2013-07-30 08:26 UTC and lasted about nine and a half minutes. Contact was telebridged via VK4KHZ. IN3GHZ served as the ARISS Mentor. The Italian Bilingual School in New South Wales Australia offers your child a unique educational opportunity to achieve excellence through bilingualism. The study of Italian offers students a window into a culture of beauty, a vehicle for creative individuality and an appreciation of the musicality in language. Italian is, after English, the most widely spoken language in Australia. Over half a million Italian Australians use the language every day. The study of Italian prepares our students for the challenges of a multicultural global community by deepening their understanding of cultural diversity. + A Successful contact was made between Oshkosh Air Venture Air Show, Oshkosh, Wisconsin, USA and Astronaut Luca Parmitano, KF5KDP using callsign NA1SS. The contact began 2013-08-01 17:01 UTC and lasted about nine and a half minutes. Contact was telebridged via AH6NM. KA3HDO served as the ARISS Mentor. With 500,000 visitors to EAA's AirVenture each year and a student membership of more than 20,000, the Experimental Aircraft Association (EAA) is a gateway to aerospace for many young people. The young people present for the contact with the space station were very diverse and reflect the range of people who are active in our organization. This includes a large group of 125 young women and their mentors as part of WomenSoar, where young women can find amazing opportunities with aerospace. Attending, also, were groups from aviation high schools from Florida and California whom participated in the ham radio contact with the ISS crew. And finally there were additional attendees of all ages who listened and participated with great interest. The EAA believes that inspiring the next generation is work worth doing. We believe in working to grow interest by sharing compelling, real life stories of people who have found rewarding careers and lifestyles through Aerospace. We hope to grow participation in aviation and space and all of its related areas through this once in a lifetime opportunity to talk with astronauts in space and the folks we will have with us on the ground. The ARISS contact an amazing way to help these outstanding students reach that goal. + A Successful contact was made between Space Jam 7 at the Octave Chanute Aerospace Museum, Rantoul, IL, USA and Astronaut Christopher J. Cassidy, KF5KDR using callsign NA1SS. The contact began 2013-08-03 20:46 UTC and lasted about nine and a half minutes. Contact was telebridged via LU8YY. AJ9N served as the ARISS Mentor. We live in a fast-paced world impacted by evolving technology. Space Jam 7 was developed to catch up with the interests and needs of our youth involved in scouting. While scouting will always address camping and pioneer skills, Our objective at the event was to teach STEM technology merit badges and skills required by tomorrow's pioneers, the astronauts. Three of our 44 major activities involved robotics. In addition to 2 Space Exploration classes we taught the Aviation merit badge (including actual flights), introduction to Scuba, Metal Work, Geology, Inventing, Electronics and Electricity. For the first time we offered Cinematography merit badge and a class where Scouts and adults could earn their ham radio license. We were attended by 2000 Boy Scouts, Girl Scouts and leaders from 20 different states, who flew, drove and took the train from across the country. 350+ volunteers put this together because they love what they do. Of course our signature merit badge was again the Duck Tape merit badge that we do just for fun. Our theme this year was the Future of Space Exploration and our answer to that implied question is not so much about going to the planet Mars but the education of these youth who will get us there and who asked questions of the astronauts aboard the International Space Station. Upcoming Contacts Epet Nº 2, Gral. Pico, Argentina, telebridge via LU8YY Contact is a go for: Tue 2013-08-06 11:48:35 UTC Ecole Primaire Pasteur, Fleurance, France, telebridge via LU1CGB Contact is a go for: Wed 2013-08-07 11:01:18 UTC ARISS is requesting listener reports for the above contacts. Due to issues with the Kenwood radio that are not fully understood at present,the Ericsson radio is going to be used for these contacts. ARISS thanks everyone in advance for their assistance. US Hams, don’t forget that there is a new process for US school proposals. For US schools to have an ARISS contact, they must fill out a proposal, submit it to NASA, and see if they are approved or not. Once a school is approved and put on the list, an ARISS mentor will be assigned to assist the school. NASA will have two open windows a year for schools to submit a proposal. You must go through NASA to get the proposal material. Contact Teaching From Space, a NASA Education office, at JSC-TFS-ARISS at mail dot nasa dot gov or by calling them at (281) 244-2320. The following US states and entities have never had an ARISS contact: Arkansas, Delaware, Kansas, North Dakota, Rhode Island, South Dakota, Vermont, Wyoming, American Samoa, Guam, Northern Marianas Islands, and the Virgin Islands. Here you will find a listing of all scheduled school contacts, and questions, other ISS related websites, IRLP and Echolink websites, and instructions for any contact that may be streamed live. http://www.amsat.org/amsat/ariss/news/arissnews.rtf A complete year by year breakdown of the contacts may be found in the file. http://www.amsat.org/amsat/ariss/news/arissnews.rtf [ANS thanks ARISS, Charlie AJ9N and Dave AA4KN for the above information] --------------------------------------------------------------------- Satellite Shorts From All Over + 432 and Above EME Newsletter is now online http://www.nitehawk.com/rasmit/em70cm.html + Frank Griffin, K4FEG, reported to the AMSAT-BB, "it is my opinion that we are quickly approaching the end of the Eclipse Cycle for AO7 this season. In May of 2014 I hope to look at the beginning of the Eclipse Cycle and work at predicting the beginning and end of it better. This has been a fun exercise for me and I appreciate those from around the world that forwarded their observations to me. Now it is time to sit and wait to see if the switches start back on August 2, 2013 at @21:00 UTC" + In a follow-up post Paul Stoetzer, N8HM, adds "The "AMSAT-OSCAR 7 Technical Operator's Plan And Experimenter's Guide" found starting on page 75 of this PDF, http://ka9q.net/AMSAT-Newsletter-1974.pdf says that the clock automatically switches the satellite to Mode B at 0000 GMT. If the clock is reset by eclipse to 0000, it stands to reason that it would always come up in Mode B out of eclipse." Paul later reported Interestingly, it looks like it's still in Mode B based on status reports, and hasn't switched to Mode A at all despite being in full illumination for more than 48 hours at this point. Even though it's not fully eclipsed at any point in it's orbit now, maybe it's still not receiving enough sunlight to remain powered up at some point during it's orbit? Telemetry reports would be very interesting to see what the onboard clock is reading. + AMSAT-NA has several presences on Social Media.

AO7 Full Illumination
by K4FEG 03 Aug '13

03 Aug '13

I have taken one final look at the time at which AO7 will come back into full sunlight and will not lose the sun any more this season. My predictions show that at /*22:55:32UTC today, AO7 will go back into full illumination*/ and no further eclipse's will occur until the Eclipse Cycle begins again next May 2014 (Exact date to be determined). /If the 24 hour Mode switch occurs on time, the satellite will be over North America and I will barely still have a footprint on the satellite on August 2, 2013 at 22:55:32UTC. // / Just as a matter of intellectual curiosity, /*if any North American operators can monitor AO7 on August 2, 2013 at 22:55:32 UTC*/, I would like to see if the /*Mode A*/ switch occurs. I will very close to my LOS when the switch will possibly happen and I may not be able to hear it. Any other reports would be appreciated so if the mode switches have started back up we can track the daily time of the switch for everyone.

Alan, Thanks for the reply. I usually don't reply to many emails here, but I feel this was necessary. I bare to disagree with you Alan. If I would have known the rig had a birdie right on the downlink frequency of two of the most popular fm birds, I would not have purchased the rig years ago. Making a statement of a "few quirks" does not give a person a fair assessment of the rig. I just feel it is a very important fact.

Newbie needs advice on which transceiver to get

Hi, I recently got interested in trying satellite communications. I bought an Arrow antenna and I am wondering which transceiver to get. So far I have found the FT-847, IC-910h and IC-9100. The FT-847 scares me since it is a bit old, however I have heard it is very good for satellite and EME. Any advice would be appreciated!! Regards, Oscar

Re: Newbie needs advice
by Michael Farkas 02 Aug '13

Depends on what you plan on doing and how much money you want to spend. I would suggest for portable operations getting a new or used name brand dual band ht like the Yaesu VX-7R or maybe a VX-8R. Check the suppliers for close outs and specials. I got my Yaesu VX-7R at real deal because they were clearing them out for the newer model VX-8 something because they actually came out with two new variants of the model. Keep in mind they work four bands. I'm starting to hear some bad things about the new "cheap" models that are out that as with I suggested staying Icom, Kenwood, Yaesu etc. I run both Elk and Arrow antennas.For base operations do the same but look for reviews on the different rigs. There are a ton of different ways to setup a home station. My rule of thumb when shopping is doing what your doing now then check the suppliers for deals, then look for used e-bay is a good source along with Hamfests!73,sMike/N8GBU

I got my TechnoTrend S2-1600 the other day and tried to get it to work on a Windows XP and a Windows 7 machine. Both machines are presently out of commission because of driver issues and an array of error codes. Seems all is not as simple as plug and play with these little monsters. I don't think I will ship it back to Europe for some other victim got get his hands on. Destruction with a 5 lb. hammer seems most likely. Anyone with a recommendation for another product that has good drivers packaged with it along with good vendor support would be welcome to contact me off line at the above address. Thanks in advance.

We and technical team of TAMSAT group would like to help and advice for circuit diagram of V/U transponder same like transponder of Japanes (FO-29) and other satellites. We had mail to Mr.William Leijenaar PE1RAH but do not have respond feedback. Mrs Thida of 100watts ham radio magazine of thailand sugges me to know Mr.William.because she meet him on Tokyo ham fair 2009.

Thanks for the mail via AMSAT.org My name is David Bowman G0MRF and I'm a member of the team building FUNcube, due for launch this November. I can help with transponder design, but there are some points which you need to consider. 1) The use of V band for the uplink will be a poor choice for your location. The interference from China and other countries on 145MHz will mean the transponder will not be usable. Using U band for the uplink is a much better choice. 2) The 100kHz bandwidth is too much for the typical power available from a CubeSat. If you get your RF team to do a link budget analysis, you will see the cubesat power budget will not support 100kHz of bandwidth. Ususally 30kHz is as much as you can do with a 1U cube. 3) You may want to consider a FM 'repeater' as there is now only 1 in orbit, while there are several linear transponder satellites ready to be launched. The FM design will allow you to run a very efficient power amplifier (70%) and power can be saved over oceans and areas of low population by using a 67Hz access tone (CML FX465) I can assist with design but would need to know if you are planning a 1U 2U or 3U design. William PE???? is good, but will probably just offer to sell you a transponder.

Alpha Spid Big-RAS AZ & EL Rotator
by Sion Chow Q. C. (9W2QC) 01 Aug '13

01 Aug '13

Dear All, I understand that the Alpha Spid Big-RAS AZ & EL Rotator requires 4 control cables each for it Azimuth and Elevation control. However, I am not able to find out if the connector on the outdoor rotator end consist of 2 separate connectors for the AZ and EL motor (like the Yaesu G-5500) or if they are connected all together at one point. Also would be great if someone could advice if the connection point consists of screw on terminals or some kind of connector plug is used. This is in preparation of ISS HAM TV reception and would like to understand the above before deciding if I should purchase this rotor. Thank you. 73, Sion Chow Q. C., 9M2CQC, WQ2C

AO7 mode switch
by K4FEG 31 Jul '13

31 Jul '13

Hello Satellite People; it is my opinion that we are quickly approaching the end of the Eclipse Cycle for AO7 this season. I had previously estimated the "final" eclipse to be on August the 2nd between 0200 and 0300 UTC but upon closer check with fresh Kep's it looks like the eclipse durations are decreasing by approximately 10 seconds per orbit at this time and with the current durations of the orbits the final eclipse of 20 seconds will end at 21:00:50UTC, when the satellite is rising over Australia. I would guess that at that point the 24 hour mode switch will begin once the satellite is in full illumination once again. It appears to have been 9 full weeks of eclipse's for AO7 and over 98% of the time it seemed to come up in Mode B, I know there were reports over Europe of a Mode A pass on individual orbits and I had noted the same for the USA as well, but once the satellite had gone into eclipse on the next orbital pass it would come back up in Mode B. In May of 2014 I hope to look at the beginning of the Eclipse Cycle and work at predicting the beginning and end of it better. This has been a fun exercise for me and I appreciate those from around the world that forwarded their observations to me. Now it is time to sit and wait to see if the switches start back on August 2, 2013 at @21:00UTC 73 ALL FRM K4FEG EM55aj84ta

We are by no means done, and welcome the assistance of others to generate content and features for the site. We are using the WordPress content management system. so changing content is much simpler than earlier schemes used on www.amsat.org. It's got a nice web based interface that should be familiar to anyone with basic word processing skills. If you see something you think you can improve on, drop me a note! -Joe KM1P

28 Jul '13

AMSAT NEWS SERVICE ANS-209 The AMSAT News Service bulletins are a free, weekly news and infor- mation service of AMSAT North America, The Radio Amateur Satellite Corporation. ANS publishes news related to Amateur Radio in Space including reports on the activities of a worldwide group of Amateur Radio operators who share an active interest in designing, building, launching and communicating through analog and digital Amateur Radio satellites. The news feed on http://www.amsat.org publishes news of Amateur Radio in Space as soon as our volunteers can post it. Please send any amateur satellite news or reports to: ans-editor at amsat.org. In this edition: * AMSAT Submits Comments to the US Government on ITAR Transition * ARISS Leadership from AMSAT and ARRL to be on-hand for EAA Airventure ARISS contact * July/August AMSAT Journal is Ready * 2013 AMSAT-NA Board of Directors Ballot Has Been Mailed * STRaND-1 Heard After 113 Days of Silence * Slime Mold Satellite gets into the media * QB50: Ham Radio transponder payloads to launch 2014 * AMSAT-UK Colloquium videos now available * AMSAT members wave at Cassini * ARISS News * Satellite Shorts From All Over SB SAT @ AMSAT $ANS-209.01 ANS-209 AMSAT News Service Weekly Bulletins AMSAT News Service Bulletin 209.01 >From AMSAT HQ SILVER SPRING, MD. DATE July 28, 2013 To All RADIO AMATEURS BID: $ANS-209.01 AMSAT Submits Comments to the US Government on ITAR Transition On May 24, 2013 the Department of State's Directorate of Defense Trade Controls (DDTC) released proposed changes to the US Munitions List (USML) Category XV ("Spacecraft Systems and Related Articles"), redefining what constitutes satellites that would remain under the USML. Satellites removed from USML will be transferred to the Department of Commerce's Commerce Control List (CCL). Consequently, the Department of Commerce's Bureau of Industry and Security (BIS) also released proposed changes on May 24, 2013 regarding modifications to the Commerce Control List, creating a separate category for satellites that were formerly controlled under ITAR (International Traffic in Arms Regulations). AMSAT President Barry Baines, WD4ASW and AMSAT Congressional Liaison Peter Portanova, WB2OQQ took on the task of drafting comments in response to the combined 105 pages of "bureaucratize" drafted by the DDTC and the BIS. Former AMSAT President Bill Tynan, W3XO crafted initial comments that provided a starting point. Peter, using various points of contact in Washington to help gauge how AMSAT might submit remarks, made recommendations on the crafting of AMSAT's response. Barry then wrote two different drafts, one addressed to the DDTC in response to the USML changes, requesting confirmation that Amateur Satellite Service spacecraft and associated equipment will be removed from the USML. The other document is addressed to the BIS in response to the proposed changes to the CCL, suggesting that Amateur Satellite Service spacecraft and associated equipment be separately categorized and controlled given the significant differences between Commercial and Amateur Satellite Service spacecraft. Both drafts were initially reviewed by the AMSAT Board of Directors with the final versions submitted on 6 JUL 13. If you would like to review both submissions they have been placed on the AMSAT website (www.amsat.org). In addition, AMSAT's submission to BIS (along with the comments of others) may be viewed at: http://tinyurl.com/k75u2go AMSAT's submission to the DDTC along with other interested parties may be found here: http://tinyurl.com/lxobvxh Note that this PDF contains "all" comments received; AMSAT's comments start on page 138. Both DDTC and BIS will now review the comments received and presumably make modifications to the original proposals. It will likely take several months before both agencies respond to the comments that they've received. [ANS thanks Barry WD4ASW for the above information] --------------------------------------------------------------------- ARISS Leadership from AMSAT and ARRL to be on-hand for EAA Airventure ARISS contact ARISS International Chair and AMSAT V.P. for Human Spaceflight, Frank Bauer, KA3HDO and ARISS U.S. delegate for the ARRL, Rosalie White, K1STO, will be supporting this week’s ARISS Contact in Oshkosh Wisconsin at Airventure, the Experimental Aircraft Association’s (EAA) annual airshow and convention, which normally hosts 500,000 visitors each year. Possessing private pilot and amateur radio licenses, Frank and Rosalie independently planned to attend Airventure this year, long before the ARISS contact was planned. “My wife Janet and I have attended Airventure 3 years straight,” Frank stated. “It is an outstanding opportunity for us to immerse ourselves in all things aviation. And it enables me to hone one of my other passions, amateur photography. When Rosalie and I heard that a contact was planned for Airventure and we learned that we were both planning a trip to Airventure, we jumped at the chance to mentor the EAA team.” While they will plan to keep a bustling agenda of “all-things aviation,” Frank, Janet and Rosalie will be focused on the ARISS contact. Planned for 12:01 CT on August 1, the contact will be conducted using the telebridge station AH6NM at the Sacred Hearts School in Hawaii. ISS astronaut Luca Parmitano, KF5KDP, plans to be at the microphone during the contact. The ARISS contact will be held as part of EAA’s Science, Technology Engineering and Math (STEM) initiative, where the focus on August 1 is space—past present and the future. Students attending the contact will include 125 women and their mentors from the EAA’s Women Sour group and students from Flabob Airport High School and Lakeland Aviation High School. Several former astronauts will also on-hand for the contact, including Charlie Precourt, KB5YSQ, who supported SAREX (STS-55 & STS- 71), Jim Voss, who supported ARISS (Expedition 2) and Kent Rominger. They will share their experiences as former astronauts and leaders in NASA’s Commercial Crew program. They will also provide the students a unique view of what it is like to perform SAREX and ARISS contacts from orbit. ARISS is an international STEM outreach program that is jointly sponsored in the U.S. by NASA, ARRL and AMSAT-NA.

The spacecraft has been silent since March 31st so this is really good news. I am certain that the project leader, Dr Chris Bridges, who presented a paper about STRaND-1 at the AMSAT-UK Colloquium last Sunday, would be really pleased to receive any and all reports from other amateurs around the world. Mike has an info page about this spacecraft here: http://www.dk3wn.info/sat/afu/sat_strand.shtml STRaND-1 transmits on frequency of 437.568 MHz (+/- 10 kHz Doppler) Please send your reports to C.P.Bridges at surrey.ac.uk A video of the presentation on STRaND-1 given on July 21 by Chris Bridges M6OBC / M0GKK to the AMSAT-UK International Space Colloquium can be seen via: http://amsat-uk.org/2013/07/23/uk-strand-1-cubesat-is-back/ Download the video by right-clicking on http://www.batc.tv/vod/strand.flv See the report from Mike Rupprecht DK3WN http://www.dk3wn.info/p/?p=35582 STRaND-1 information http://amsat-uk.org/satellites/strand-1/ How to decode the telemetry http://amsat-uk.org/satellites/strand-1/strand-1-telemetry/ [ANS thanks Graham G3VZV, Mike DK3WN and Trevor M5AKA for the above information] --------------------------------------------------------------------- Slime Mold Satellite gets into the media A brief mention of the Slime Mold CubeSat posted last March on the AMSAT-UK and Southgatearc.org sites has been picked up by one of the Space.Com website writers, Leonard David, who has written a good article which retained a mention of amateur radio. It's Summer in the northern hemisphereand media outlets can be short of stories at this time of year so Leonards story has in turn been picked up by a few other news outlets and hopefully that will spread. I guess the thought of Slime in Space captures the imagination.Most of the resulting stories seem to have retained the mention of amateur radio. You can read Leonard David's article at http://www.space.com/21982-space-slime-grows-mold-tiny-satellite.html March AUK mention http://amsat-uk.org/2013/03/15/teikyosat-3-slime-mold-from-space/ [ANS thanks Trevor M5AKA for the above information] --------------------------------------------------------------------- QB50: Ham Radio transponder payloads to launch 2014 It was announced during the QB50 presentation at the AMSAT-UK International Space Colloquium that two CubeSats, carrying SSB/CW and FM voice transponders should be launched into a 600 km orbit in the first half of 2014 The QB50 project team has announced that on July 19, 2013 they signed a Memorandum of Understanding with AMSAT-UK, AMSAT- Francophone, and AMSAT-NL to enable two amateur radio payloads to fly on two 2-Unit CubeSats in the first half of 2014. These precursor CubeSats, which have still to be named, will be placed into a conventional 600 km 98o orbit in advance of the main mission. This allows for the testing of key satellite and payload components ahead of the full QB50 mission. In addition, the precursor mission allows for experimentation and validation of operational concept of the QB50 mission. Next to these objectives the amateur radio payloads will be operated as well. At the beginning of the mission, the various payloads onboard the spacecraft will be operated in an alternating fashion, whilst the amateur radio payloads will be operated as the primary payload of the spacecraft once all QB50 related experimentation has been concluded. The main mission of QB50 has the scientific objective to study in situ the temporal and spatial variations of a number of key constituents and parameters in the lower thermosphere (90-320 km) with a network of about 40 double CubeSats. These, university built, CubeSats will be launched into a 320km circular orbit, will be separated by a few hundred kilometres and carry identical science sensors. The sensors will monitor parameters that will greatly increase our knowledge and understanding of this little explored region of the E and F layers of the Ionosphere. QB50 will also study the re-entry process by measuring a number of key parameters during re-entry and by comparing predicted and actual CubeSat trajectories and orbital lifetimes. The AMSAT-Francophone (AMSAT-F) payload for one of the satellites will be an FM voice relay with VHF uplink and UHF downlink. It will also transmit FX25 telemetry at 9.6kbit. This secondary payload will be also used in several satellites in the main constellation as their main receiver and transmitter. The AMSAT-NL payload, on the other precursor satellite, will incorporate an SDR based, linear, V/U, transponder core and is being designed to allow the uploading of firmware updates to enable enhanced performance and functionality. It will also provide a telemetry downlink at 1.2kbit using FUNcube compatible BPSK modulation. The QB50 spacecraft in the main, short duration, mission will, generally, have downlinks operating on frequencies in the 435-438 MHz Amateur Satellite Service allocation and some are expected to use 2.4GHz. They will be notified to the ITU as a Belgian network after having been coordinated by the IARU Frequency Coordination Panel. Some of these will also, on occasions, act as FM voice relays during their missions.

XE2HWB from DL43 - this weekend (27-28 July)
by Patrick STODDARD (WD9EWK/VA7EWK) 25 Jul '13

25 Jul '13

Hi! I received an e-mail from Bernardo XE2HWB, a long-time VHF/UHF operator based in La Paz in southern Baja California who has also worked satellites. Bernardo is leaving tomorrow to go out to the Sierra de la Laguna in grid DL43. He plans on working SO-50, FO-29, and VO-52 passes on Saturday (27 July) and Sunday (28 July), although he did not specify which passes he would try to be on over those two days. Along with his satellite work, XE2HWB will also be on 6m. It's been a while since XE2HWB has activated rarely-heard grids on the Baja California peninsula, and in the past he would confine his satellite activity to the FM satellites. It is nice to see his plan to try working FO-29 and VO-52 along with our remaining FM satellite. Good luck, and 73! Patrick WD9EWK/VA7EWK http://www.wd9ewk.net/

Yubileiny (RS-30) ?
by Jean-Pierre Godet 23 Jul '13

23 Jul '13

Hi all here ! Looks like Yubileiny/RS-30 is no more active... Is there anyone among us who could confirm ? Last record here was on November 12th 2012, heard maybe some time in december but nothing now. I'm listening in vain for more than a week on 435.215 and 435.315 MHz. Last pass, orb. nr 23440 has a max elevation 68 deg. Yubileiny-2/RS-40 is OK but active only when in sight of Krasnoyarsk. Yesterday was on 435.265 MHz (DOKA-B, not CW, two pass recorded). Best 73 !

CAPE-2 Tweeting From Space
by Rizwan 'Drake' Merchant 23 Jul '13

23 Jul '13

Greetings AMSAT! A few weeks ago, I emailed out asking for help on figuring out how to tweet from our CAPE-2 cubesat while it is in orbit using APRS. I am pleased to announce, the satellite is now capable of tweeting. I realize our launch is still a little ways away, but I thought I would pass the community our twitter account to follow. Expect occasional tweets from the account as we test different modules out. :) Twitter: https://twitter.com/CAPE_2 Thanks to everyone who helped our team brainstorm how to make this a reality!

Satellite Operations from Guernsey
by Peter Goodhall 22 Jul '13

22 Jul '13

Hi All, Just a quick note to say that from the 24th of July till the 30th of July, I will be active sporadically on satellite passes from Guernsey (IN89RL) as 2U0SQL. I shall be focusing on FO-29 and SO-50 passes but no firm pass times, but hopefully will have internet access and will try posting on Twitter (@2E0SQL) when I'll be on. Due to this being camping I will be battery powered using a FT-817 and a Arrow antenna. If anyone needs a QSL Card its direct to 2E0SQL or bureau. 73, -- Peter Goodhall, 2E0SQL/2U0SQL

Slime Mold CubeSat gets into the media
by M5AKA 22 Jul '13

22 Jul '13

A brief mention of the Slime Mold CubeSat posted last March on the AMSAT-UK and Southgatearc.org sites has been picked up by one of the Space.Com website writers, Leonard David, who has written a good article which retained a mention of amateur radio. It's Summer in the northern hemisphereand media outlets can be short of stories at this time of year so Leonards story has in turn been picked up by a few other news outlets and hopefully that will spread. I guess the thought of Slime in Space captures the imagination.Most of the resulting stories seem to have retained the mention of amateur radio. You can read Leonard David's article at http://www.space.com/21982-space-slime-grows-mold-tiny-satellite.html March AUK mention http://amsat-uk.org/2013/03/15/teikyosat-3-slime-mold-from-space/ 73 Trevor M5AKA ----

1/2 Wave "cavity" filter design?
by Robert Bruninga 21 Jul '13

21 Jul '13

Given the classic 1/2 wave cavity filter, what is the relationship between inner cavity and center conductor sizes? Of course bigger is better, but what is "OK". This is a 1/2 wavelength tube with a center conductor shorted at each end. The input is loop coupled at one end, an output is loop coupled at the other end. In the middle is a tiny variable capacitor (usually just a screw) to tune to resonance. In the limit, as the cavity size shrinks, you can end up with what could be considered as just a piece of 1/2wave coax. Im looking for a really cheap Home-Depot plumbing design that 15 people can reproduce to give them good front end antenna filtering when operating on mountain tops adjacent to other RF souces. (say within 100 yards, not permanent installations which of course should spare no expense at getting the best cavities possible). We just finished our 4th annual Golden Packet attempt from Maine to Georgia along the Appalachian trail and many stations were plagued with front end overload. http://aprs.org/at-golden-packet.html I'd like to come up with a 3/4" copper pipe design that is robust, provides sevral dB of out of band rejection. Im trying to understand the parameters that drive the size of the center conductor. Normally bigger is better for better bandwidth, but I think smaller will give me steeper skirts and better rejection? I dont mind say 2 or more dB insertion loss, because as it is, front end-overload is making us totally deaf and anything would be bettter. Lastly, I think such a 1/2wave filter will also pass as a 1.5wave pass filter on UHF. We need dual band, since we use dual band rigs and coordinate on UHF voice from the same antennas and coax used for the VHF packet.
