Re: FT 847 vs. IC-910H
by WILLIAMS MICHAEL 22 Apr '12

Ted, Stephan gives some great comments on all three radios. As for the 847 on HF, I think there is a audio clip on the internet comparing the 847 and TenTec Corsair II receivers. I have both of these rigs and the difference is very clear. Listening to my 847 on HF is not a pleasurable experience as the receiver is very noisy. For this reason, my old Corsair II does all HF work at least until I get a new HF rig. Eham reviews on the Corsair attest to its great receiver. As for satellite operations, the 847 is a tough and a great rig. Mine has been running since the beginnings of AO-40 with no problems. It has some engineering mistakes like the AF gain not being linear along with other quirks but I've gotten my investment back many times over. If you've got the cash, I would read the QST review on the 9100 and make an executive decision. GL Mike (K9QHO)

FT 847 vs. IC-910H
by Ted 21 Apr '12

21 Apr '12

I think I'm having some 'buyer's remorse' over my purchase of the 910H I would like to have some input from the sat group as to why one radio is overwhelmingly compelling over the other for sat work. (I am aware of the power diff) FYI, It's not likely that I will ever go to the full on 100+ el ant display with all the bells and whistles, (like that John guy in Ohio hi hi, but ya never know). (and although there is a NIB Kenpro 5400R and a FD-ST3 sitting on the floor in here !) I do a lot of digital HF modes and am thinking maybe that the 847 might be a better use of a combo radio.( I have a TS-2000, but oh those birdies !!) Any thoughts appreciated 73, Ted, K7TRK (VUCC #226)

This four-day professional development workshop is spon- sored by the Dayton Amateur Radio Association and is held in their location in Dayton, Ohio (July 9-12). The TI-2 Space curriculum focuses on the nuts and bolts of setting up and operating a satellite ground station. This serves as excellent preparation for a scheduled contact with the ISS through the Amateur Radio on the International Space Station (ARISS) program. But it also provides instruction for continued use of satellites and other man made space assets to explore naturally generated signals, space and a variety of topics. Thanks to generous assistance from Yaesu USA and Ham Radio Outlet, participants will receive a full ground station that is configured for satellite communications, as well as training on how to set it up and use it to make Amateur Radio contacts and download telemetry data. To be considered for a seat in TI-2 Space, participants must possess at least a Technician class license at the time off application. ARRL membership is required. Priority for attending the TI-2 Space session will be given to teachers who have developed an educational proposal accepted for participation in the ARISS Program. This session has a class limit of 8 participants, so apply early! The deadline for the TI-2 Space in the Classroom sessions of the Teachers Institute is May 15. Full details are posted on the ARRL web at: http://www.arrl.org/ti-2-space-in-the-classroom [ANS thanks the ARRL for the above information] --------------------------------------------------------------------- Five CubeSats in Preparation for July Launch to ISS Five CubeSat teams continue work on preparations for a launch to the International Space Station in the July 18-21, 2012 time frame. These CubeSats will be launched from Tanegashima, Japan aboard the JAXA HTV-3 ISS resupply mission. The CubeSats will be loaded into the J-SSOD deployer on the Japanese Experiment Module, also known as Kibo. They will be deployed with the Kibo robotic arm planned for September, 2012 timeframe. The five CubeSats include: + Raiko + We Wish + FITSat 1 + F-1 Vietnam Student CubeSat + TechEdSat RAIKO - Wakayama University, Japan ---------------------------------- http://www.astro.mech.tohoku.ac.jp/RAIKO/ (Japanese) This 2U CubeSat includes experiments for: + Earth photography with a fish-eye lens camera + Photo tracking during deployment from ISS to measure relative motion. + Experimental star sensor + Membrane deployment experiment for de-orbit + High speed data communication experiment by Ku-band communication equipment: o Orbit determination experiment by Doppler frequency measurement of Ku-band beacon. o Mobile ground station and global cooperation for reception FITSAT-1 - Fukuoka Institute of Technology, Japan ------------------------------------------------- http://www.fit.ac.jp/~tanaka/fitsat.shtml The main mission of this 1U CubeSat will be a demonstration of high speed data transfer from a satellite. A second experiment aboard the satellite involves an attempt at visual tracking from the ground of the high-output LED flash to investigate the possibility of optical communication with satellites. The light from this flash will be re- ceived by the ground station equipped with a telescope with photo- multiplier linked to a parabolic antenna tracking the 5.8GHz downlink. Frequencies announced for FITSAT-1: CW Beacon 437.250 MHz, FM Data 437.445 MHz, High speed data 5840.00 MHz.

This includes GPS technology, and technical proof of concept of a micro infra-red camera. The team has the additional goal of contributing to local technical education through the use of CubeSat ground data acquisition. F-1 Vietnam Student CubeSat --------------------------- Vietnamese students in Hanoi plan to orbit the country's first sat- ellite, their amateur radio CubeSat F-1 with the callsign XV1VN. The satellite will carry a low resolution C328 camera and two Yaesu VX-3R transceivers using 145.980 and 437.485 MHz. + VX-3R1, 437.485 MHz FM downlink: o Solar cell power only, operates in sunlight only o Output power: max 0.3W, half-wave dipole antenna o Morse code beacon (10 chars) using PWM CW every 30 seconds + VX-3R2, 145.980 MHz FM downlink: o Rechargeable battery, operates in dark and sunlight o Output power: max 1.0W, half-wave dipole antenna o AFSK 1200bps, half duplex, one AX.25 packet every 30 seconds If the The F-1 web page at: http://fspace.edu.vn is not available the latest news and photos have been posted on the AMSAT-UK web: http://www.uk.amsat.org/5025 TechEdSat - San Jose State University ------------------------------------- http://ncasst.org/techedsat.html http://www.uk.amsat.org/5018 TechEdSat is a 1U CubeSat built by San Jose State University in part- nership with NASA Ames Research Center and AAC Microtec. It's mission is to evaluate Space Plug-and-play Avionics (SPA) designed in Sweden by AAC Microtec, and to perform a communications experiment utilizing the Iridium and Orbcomm satellite phone network. Student hands-on learning opportunities were presented during the International Space Apps Challenge on April 21-22. For this challenge, space hackers implemented a fault-tolerant command and control system, utilizing both the OrbComm and Iridium modems as uplink and downlink. Ground segment of the software includes the ability for a laptop, Apple or Android phone to issue commands to the spacecraft over Iridium/Orb- comm. The students will also be challenged with designing the capa- bility for relaying data received from the spacecraft automatically to Twitter. TechEdSat has received IARU frequency coordination for its downlink on 437.465 MHz.

This is an auxiliary payload platform to allow multiple CubeSats to be launched aboard rockets as secondary payload meaning the rocket would be able to carry satellites in onboard space that would otherwise be unused. NPSCuL can accommodate up to 24 CubeSats in a single ESPA-class [Sec- ondary Payload Adapter] payload volume. Upon reaching the desired orbit spring-loaded doors will release the satellites one-by-one. First flight is planned for August 2012 which will carry 11 CubeSats for the Operationally Unique Technologies Satellite (OUTSat). This will enable NPS researchers to get one of their own CubeSats into space. The NPS STARE CubeSat is part of a collaborative effort be- tween NPS and the Lawrence Livermore National Laboratory (LLNL) on a proof-of-concept mission to observe other satellites and help deter mine threats posed by space debris. The NPS has published a press release available on-line at: http://tinyurl.com/CubeSat-NPSCuL (www.nps.edu).

Cotopaxi, an international Ameri- can school with students in grades pre-K to 12, has a strong relation- ship with Ecuador's astronaut, Ronnie Nader, and the Ecuadorian Civ- ilian Space Agency (EXA). It utilized several NASA resources in its curriculum covering space, technology and radio. Approximately 500 students and visitors were present for the event. Saitama Scout Council Japan --------------------------- Scouts from the Troop 2nd & 3rd Iruma Group, Saitama Scout Council, Scout Association of Japan participated in an ARISS contact on Satur- day, April 14. An audience of 70 people, including one magazine rep- resentative, turned out for the contact and listened as the Scouts had their questions about living on the ISS answered by on-orbit astronaut Dan Burbank, KC5ZSX. The Scouts have their own radio club, JQ1YWJ and many of the Scouts have been attending amateur radio classes to become licensed. Flabob Airport Preparatory Academy California --------------------------------------------- The Flabob Airport Preparatory Academy in Riverside, California had a successful ARISS contact on Thursday, April 19. The telebridge sta tion IK1SLD in Italy provided the radio connection with the ISS. The ARISS contact complemented a comprehensive education plan to pique students' interest in Science, Technology, Engineering and Math (STEM). After the event, ARISS mentor Clint Bradford, K6LCS declared, "SUCCESS at Flabob Airport this morning! Flight engineer Pettit answered all seventeen of our questions - from fifteen students." There were 211 in the audience, including 120 Flabob students, media, city council members, Gordon West and Don Arnold, and other dignitaries, AND a lot of parents, too! Media coverage of the Flabob ARISS contact included California's sixth largest daily newspaper, The Press-Enterprise, sent a reporter, video- grapher, and photographer, the Bob Heil & Gordon West mediacast, Ham Nation, sent a videographer - and the contact will be on an episode of their webcast in the next couple of weeks. Newspaper coverage in- cluded the editor and publisher of The Riverside County Record. Clint was interviewed on PBS radio affiliate KVCR. The Inland Empire Tele- vision Network videotaped the entire event. The Press-Enterprise is the region's major newspaper. Links to their video, article, and photographs are posted on ISS-Flabob site blog at: http://www.iss-flabob.com/ISS-Flabob/Blog/Blog.html Clint invites you to check out http://www.iss-flabob.com since this site created for the ARISS event also offers links and publications on amateur radio, our space programs, ARISS, AMSAT, ARRL, ham radio licensing - and MORE - on the MORE INFO page.

Each year the American Radio Relay League (ARRL) sponsors Field Day as an emergency preparedness exercise. The event takes place during a 24-hour period on the fourth weekend of June. For 2012 the event takes place during a 27-hour period between 1800 UTC on Saturday, June 23, 2012 and 2100 UTC on Sunday June 24, 2012. Those who set up prior to 1800 UTC on June 23 can operate only 24 hours. The Radio Amateur Satellite Corporation (AMSAT) promotes its own ver- sion of Field Day for operation via the amateur satellites, held con- currently with the ARRL event. With the loss of AO-51 and SO-67 field day this year is going to be most challenging. If you are considering ONLY the FM voice satellites like AMRAD-OSCAR-27 or SaudiSat-Oscar-50 for your primary AMSAT Field Day focus: Don't, unless you are simply hoping to make one contact for the ARRL rules bonus points. The congestion on FM LEO satellites was so intense in prior years that we must continue to limit their use to one-QSO-per-FM-satellite. This includes the International Space Station. You will be allowed one QSO if the ISS is operating Voice. You will also be allowed one digital QSO with the ISS or any other digital, non-store-and-forward, packet satellite (if operational). If you have worked the satellites on Field Day in recent years, you may have noticed a lot of good contacts can be made on some of the less-populated, low-earth-orbit satellites like VUSat OSCAR-52,Fuji- OSCAR 29 (may or may not be operational), AMSAT-OSCAR 7. During Field Day the transponders come alive like 20 meters on a weekend. The good news is that the transponders on these satellites will support multi- ple simultaneous contacts. The bad news is that you can't use FM, just low duty cycle modes like SSB and CW. The AMSAT Field Day 2012 event is open to all Amateur Radio operators. Amateurs are to use the exchange as specified in ARRL rules for Field Day. The AMSAT competition is to encourage the use of all amateur sat- ellites, both analog and digital. For the complete listing of the AMSAT Field Day Rules please refer to the documents posted on-line at: http://www.amsatnet.com/fd2012.doc http://www.amsatnet.com/fd2012.pdf Links are also accessible from http://www.amsat.org front page.

The Amateur Service allocation in this band is on a secondary basis, with aeronautical radionavigation and several other services primary in the United States Table of Frequency Allocations. The FCC rules require that amateur stations operating in the 23 cm band may not cause harmful interference to stations in the radionavigation-satel- lite service, the aeronautical radionavigation service, the Earth exploration-satellite service or the space research service. One case of harmful interference in Southern California has been re- ported. CARSRs are being installed in several dozen locations through- out the country and will use various frequencies in the 1240-1350 MHz range with an occupied bandwidth of about 3 MHz. In the vicinity of the radars, amateur operation may be precluded in a portion of the 23 cm band. The ARRL is in contact with FAA engineers. The ARRL said they anticipate that the constraints on amateur use of the band will be limited to those necessary to protect aviation safety, which of course cannot be compromised. The bulletin is posted on the ARRL web at: http://www.arrl.org/news/amateurs-must-protect-new-radars-in-23-cm-band [ANS thanks the ARRL for the above information] --------------------------------------------------------------------- AMSAT-UK on Satellites for World Amateur Radio Day Members of AMSAT-UK operated on the amateur radio satellites from the RSGB National Radio Centre at Bletchley Park to celebrate World Amateur Radio Day (WARD) on Wednesday, April 18, 2012. World Amateur Radio Day commemorates the founding of the Internation- al Amateur Radio Union (IARU) on April 18, 1925. This year's theme was "Amateur Radio Satellites: Celebrating 50 Years in Space" in re- membrance of the launching of OSCAR 1 on December 12, 1961 and the launch of OSCAR 2 on June 2, 1962. Those taking part in the event were Jim G3WGM, Dave G4DPZ, Trevor M5AKA, Ciaran M0XTD, Matthew SWL, Clive G3CWV, Carlos G0AKI and Elaine G4LFM. The satellites worked during the day included FO-29 and AO-7 and contacts were made with stations across Europe using the 144 and 430 MHz bands. The equipment used comprised a Kenwood TS-2000 with WiMo X quads for 144 and 430 MHz, with pre amps and polarisation switches. Read the rest of this article, along with links to photos and video on-line on the AMSAT-UK web: http://www.uk.amsat.org/6516 [ANS thanks AMSAT-UK for the above information] --------------------------------------------------------------------- UK Will Restrict Use of Amateur Satellite Frequencies During Olympics Trevor, M5AKA has filed the following notice on the AMSAT-UK web. The Olympic and Paralympic Games will be using almost half of the 430 MHz amateur radio allocation as well as segments of 2.3 GHz and 3.4 GHz during the period June 28 to September 23. The impact on the Amateur-satellite Service 435-438 MHz allocation has been restricted to 436.25-437.25 MHz. It is understood that the equipment being used in the 430 MHz band will include handheld FM rigs at the hotels, the routes to the venues and the venues them- selves. The UK communications regulator Ofcom has provided details of the areas that need to be protected from RF within the designated fre- quency ranges. Follow the link to the AMSAT-UK web provided below for the details of the region affected by the restrictions. Ofcom say the use of radio by Amateurs in the designated areas could cause interference to Games applications; it is also possible that higher power transmissions from outside these areas could cause in- terference. Consequently, to avoid the risk of interference to Games applications, Ofcom request that Amateurs do not operate within the frequency ranges identified in the areas defined in Annexes A and B, and that Amateurs ensure that any signals that could be received in these areas are negligible. This indicates that the specified fre- quency ranges should be avoided for a considerable distance outside the designated zones. Clearly a well equipped station on a good site 75 km from the edge of a zone could still put a signal into that area.

Greg had a a heart attack on April 18 and did not survive it. He just turned 48 in February. He is survived by his 18 year old son Rick Tillman, WA4NVM noted, "Greg was one of the truly nice guys, always polite and there to help. It's been our great pleasure and privilege to know and work with him in the Memphis ham community. He will truly be missed. God bless your soul faithful servant," John Papay, K8YSE recalled, "Greg was one of the most courteous operators that I've known. He was active on the birds and enjoyed working new grids. Greg was a gentlemen. We will miss hearing his voice on the birds."

Hi all, I have been having issues with Echolink...so I haven't been able to run my own net! Although...feel free to use the net reflector if I am not present. Does anyone know why my mic will not work with Echolink?

New use for APRS
by Jim Wright 21 Apr '12

21 Apr '12

Battery condition tester? When I got out of my Silverado last weekend with the Kenwood 710 left on in beacon mode and voice alert, the dummy that was driving forgot to turn off the 710. After sitting for a week in this condition while I went in for surgery, the battery was dead when I tried to start the truck today. First I thought the key fob battery was dead, so I entered with a key. Truck would not start, not even the errrrhhhhh or click click of the flywheel trying to engage. I was curious how long it was able to transmit, so I went to APRS.FI and looked for my last 1000 raw packets. It turns out that it died on 04-19 at 0412utc. A search will show the next packet was at22:05:19utc on 4-21, so this makes a good monitor of when the radiio is too weak to speak APRS. I thought you would get a chuckle out of this and maybe even produce an app for our cell phones that will tell us we left the radio on. HI I know the 710 is not wired through a switched connection to the battery (on purpose) so I can work events with the keys in my pocket. 73, and thanks for all the fun I have had since I heard packet racket for the first time on K4UMI's 146.34/94 repeater at the Lunar Lander at NACA Langley and got a GLB PK1 to decode it with.
