ARISS special event thanks and suggestion
by andy thomas 21 Dec '08

21 Dec '08

My greatest thanks for this special ARISS event. It's new challenges encourage me to hone my equipment up to standard (which is arguably the serious point of the thing). My frustration has been that due to work commitments (which I do in my spare time from satellites, hi) I haven't had any time except weekends, and just got my 9k6 tnc adjusted so that it'll properly modulate my rig, and the 9k6 effort has now stopped. But I see that there's a programme gap between the 3rd and 15th of January? So I am sending this to the -bb because others may have their wish list too!! 73 de andy g0SFJ

Thanks Joanne! I would think that it might also hear the short 1 sec pings of any big satllites (ISS etc) that also went through it unless they have filered those out somehow... Easy to check. Just put a gnd station at the coordinates of kikapoo texas and watch for any ISS or hubble etc passes the instant they pass an azimuth of 91.5 or 271.5 fro m Kikapoo.

Here's something to do while waiting for the next satellite pass ... http://spaceweather.com/ has an audio feed of the meteor pings from the Ursid Meteor Shower as they pass through the Air Force Space Surveillance Radar in Texas. Note: the Ursid radiant is circumpolar (always up) over the radar so the echoes may be heard at any hour, night or day. I've heard 4 pings over the past 45 minutes of listening this morning. -- 73 de JoAnne K9JKM k9jkm(a)amsat.org Editor, AMSAT News Service Copy Editor, AMSAT Journal

Eurpoean IC-910 CTCSS disabled? ISS contact implication!
by andy thomas 21 Dec '08

21 Dec '08

Hi according to the manual, CTCSS encoding is disabled on all IC-910 s in Europe, Sweden and Italy! I can set it in tone squelch but does that tx it too when in satellite mode? Otherwise it won't be possible for me and other IC910s over here to contact the ISS in the new repeater mode (which I don't think is in operation yet anyway). andy G0SFJ

20 Dec '08

AMSAT NEWS SERVICE ANS-356 ANS is a free, weekly, news and information service of AMSAT North America, The Radio Amateur Satellite Corporation. ANS 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. Please send any amateur satellite news or reports to: ans-editor(a)amsat.org In this edition: * AMSAT President's Letter * ARISS 25th Anniversary Adds New Modes * ARISS Discusses L-Band Operating Parameters * Tracking QRM - AO-51 Repeater Pairs Return to Normal Configuration * PCSAT-1 Recovery Partial Success * Satellite Shorts From All Over * Mark Your Calendars - 2009 AMSAT Symposium October 9-10 * Reminder: SKN on OSCAR 2009 SB SAT @ AMSAT $ANS-356.01 AMSAT President's Letter AMSAT News Service Bulletin 356.01 >From AMSAT HQ SILVER SPRING, MD. December 21, 2008 To All RADIO AMATEURS BID: $ANS-356.01 Happy Holidays! Best wishes to everyone during this festive time of the year. As I write this, a major snowstorm is pro- viding plenty of 'white stuff' in the Midwest and New England, so I presume this means that we will have a white Christmas here in Massachusetts. While this is certainly a time of economic uncertainty, I also know that our members continue to make a difference for AMSAT. A number of interesting opportunities and events have developed over the past two months for AMSAT that I would like to briefly share with you: 1. ARISS Silver Anniversary. The first amateur radio two-way communication between the Space Shuttle and amateurs on the ground took place on December 3, 1983 when Owen Garriott, W5LFL made his historic flight on STS-9. There are a number of oppor- tunities for amateurs to help celebrate this event and the ARISS International Committee, chaired by AMSAT VP-Human Space Flight, Frank Bauer, KA3HDO have arranged for some special events. Please check ANS and the AMSAT webpage (www.amsat.org) for the latest information and join the fun! 2. AO-16 operations. As expected, performance of this spacecraft is declining as the spacecraft's temperature is dropping due to longer eclipses resulting in less sunlight and a cooler spacecraft. This drop in temperature is causing the satellite's hardware timer to reset until the spacecraft warms up (when there is at least 85% illumination). If you're interested in making two-way contacts using AO-16's unique cross mode, cross band voice repeater, with an uplink on 145.920 FM and downlink on 437.026 MHz reduced carrier AM, now is the time to try it! The satellite is expected to 'go silent' shortly when temperatures stay low enough as to not allow software configuration of the satellite before the hardware timer resets itself again. 3. President's Club. A fundraising appeal letter was mailed this week to all AMSAT members. Please consider donating to the AMSAT President's Club so that we can continue our efforts to maintain amateur radio in space. 4. Near Term Engineering Task Force. I announced at the AMSAT Annual Meeting in Atlanta that a group led by Bill Ress, N6GHZ had been formed to review the 'Rideshare' Proposal developed by Tom Clark, K3IO as well as evaluate AMSAT's ability to develop a modularization strategy to adapt RF packages to various structures. The committee has been diligently meeting every two weeks via tele- conference to discuss future options for AMSAT and to help structure AMSAT's thinking on future spacecraft opportunities. While it is too soon for formal announcements of their findings, it is good to know that we have a formal group actively focused on engineering issues. 5. SuitSat-2. Development work continues to place SuitSat-2 in service sometime in 2009. Several engineering issues have recently surfaced regarding modulation and transmission schemes and the team is evaluating several options regarding how best to resolve the issues. Several individuals have recently joined the engineering team to help overcome these challenges by developing potential alternative solutions. 6. ITAR. I announced at the AMSAT Annual Meeting in Atlanta that AMSAT would actively develop a strategy concerning ITAR (International Traffic in Arms Regulations) and related export regulations. Our goal is to ensure that AMSAT is in full compliance with ITAR, develop materials to train our satellite builders on ITAR compliance, and to seek ways where we may continue to work with other AMSAT organizations on satel- lite projects. Since the Annual Meeting, Bill Ress, N6GHZ and I have been working with an attorney who specializes in ITAR. We hope to make a formal submission to the State Department regarding ITAR in early 2009. 7. AMSAT Lab. AMSAT is actively seeking a new home for our AMSAT Lab. Unfortunately, due to changes that took place at HISS (Hawk Institute for Space Sciences) in Pocomoke City, MD over the summer, we are forced to remove our equipment and clean room from the current facility. We are in active discussions with several institutions concerning potential relocation, but no decision has been made. If you are in position to provide contacts with a not-for-profit institution that might be inter- ested the hosting the AMSAT Lab, please contact me. 8. AMSAT 40th Anniversary. AMSAT was incorporated in 1969, so this coming year (2009) is our 40th Anniversary! The 2009 AMSAT Symposium will take place the weekend of October 9 in the Washington-Baltimore area. Look for details in the upcoming AMSAT Journal. Please join us that weekend as we celebrate a significant milestone for AMSAT and build the foundation for the next 40 years of AMSAT. As you can see, there are a number of activities that are ongoing within AMSAT. While we are challenged by the impact of current events, we con- tinue to move forward in a number of areas. As always, I appreciate hearing from the AMSAT membership. Should you have any questions or concerns about AMSAT, please don't hesitate to contact me. I will make every effort to respond to e-mails that I receive, but please keep in mind that I travel extensively which may limit my ability to respond quickly. Please know that I read every e-mail that I receive from AMSAT members and that I appreciate every person's willingness and time spent to share their thoughts and suggestions.

December 21, 2008 To All RADIO AMATEURS BID: $ANS-356.02 ARISS International Chairman and AMSAT-NA V.P. for Human Spaceflight Programs Frank Bauer, KA3HDO invites amateur radio operators around the world to join in the ARISS team's 25th anniversary of amateur radio operations from space. Increased activity and new exciting modes of operation from the ARISS amateur radio station aboard the International Space Station are featured in this celebration operating period. To date, the ISS crew has configured the radio to support cross-band repeater operations, they have supported some SSTV downlinks and we have had the opporunity to participate in a special test of 9600 baud packet radio operations on the simplex frequency of 145.825 MHz. This past week featured 1200 baud packet operations on 145.825 MHz to open a dual-hop APRS path in case PCSAT-1 became operational. For the upcoming weeks the following is being planned in the near-term: + December 21-26 - we plan to support the Crossband repeater mode with a twist. Our intent is to configure the radio for 145.99 MHz uplink including PL tone of 67.0 and 437.80 MHz down. This will be performed in low power mode. + December 22 - Expedition 18 Commander Mike Fincke and Flight Engineer Yury Lonchakov plan to perform a spacewalk. As per standard procedure, the ISS ham radio system will be turned off for the EVA. + December 28-January 3 - we plan to reconfigure the Crossband repeater for a special experiment. This will be a test of our L-Band uplink capability, which, to date, has not been proven out. Plan for an uplink of 1269.65 MHz and and downlink on the standard frequency 145.80 MHz using low power. Given the subtan- tial cable losses of the L-band system, we hope some "big guns" are able to penetrate through, keep up with doppler, and make the connection. + And at times, especially during the weekends, you might see some SSTV operations if the crew is available. The ARISS team will provide more updates in the near future. They would like to remind everyone that ISS flight requirements related to EVA and vehicle activity may require the radio to be off for some portion of this schedule. And school contacts and general QSO oppor- tunities by the crew will also preempt this schedule for short periods of time.

December 21, 2008 To All RADIO AMATEURS BID: $ANS-356.03 ARISS US Hardware Manager Lou McFadin, W5DID provided a summary of expected parameters for those considering trying to make a contact with the ISS on L-band to VHF crossband repeater experiment planned for December 28 to January 3. Lou reported, "The measured sensitivity of the L band receiver on a D700, as the radio aboard the ISS, is -105dBm for full quieting. The cable loss from the radio to the antenna is 9.3db. The antenna gain is zero db. The polarization is LHCP." Extending the calcuations to cover the entire system path, Lou said, "The path loss at the horizon on L band is -160dB. That means the required EIRP for a full quieting contact at the horizon is 65dBm. The path loss decreases by 15dB at 80 degrees elevation so that means you can get full quieting with 50dBm in that case. To further elaborate if you use a 20dB gain antenna (a small dish), it is estimated that you can complete a QSO with 32 watts at the horizon or 1 watt at 80 degrees elevation."

December 21, 2008 To All RADIO AMATEURS BID: $ANS-356.04 AMSAT-NA VP Operations, Drew KO4MA reported on behalf of the AO-51 Operations Team, "We are now back to the normal uplink arrangement of 145.920 and 435.300 for normal repeater use. We changed from the QRM mitigation experiment of operating via the 145.880 uplink back to this normal mode to enable low-power repeater QRP operation. The QRP repeater is now operational on 145.880 and 435.150." As a result of the QRM investigation Drew said, "I'm convinced not all of our problems are related to the cordless phones. I heard tonight whistlers, blowing in the mike, and folks giving extended CQs. We are working on finding the general location of the cordless phones, but it takes time. Then we'll work at shutting them down. The AO-51 Operations Team provided results of their QRM investigation on and around the 145.920 uplink. There may be some low level modula- tion on some of the signals in the captured waterfall diagram. It is believed they may be from some of the same long distance phones that were plauging AO-27 and SO-50 a few years ago. Observations indicate the interfering signals are lost about the time the edge of the foot- print crosses the mid Atlantic states.

December 21, 2008 To All RADIO AMATEURS BID: $ANS-356.05 Bob, WB4APR provided an update on PCSAT-1 recovery status from the U.S. Naval Academy Satellite Laboratory. Bob wrote, "For the first time in 7 years, we were not able to fully recover PCSAT during this full sun period despite the efforts of a number of dedicated volun- teers around the world." PCSAT-1 is only operation when its solar panels are illuminated by sunlight. Full sun periods occur when passes are at sunrise and sunset to earth observers. PCSAT gets sun 24 hours a day then, but only on the side panels due to the orientation of the satellite. Ground station controllers were able to recover PCSAT-1 and the weak solar illumination allowed operation for generally an orbit before the power budget could not support the load. Bob summarized, "Anyway, this is not the last you will hear of PCSAT, but there will probably not be any more several week full sun, full recovery periods as there have been in the past. I really appreciate all the efforts of so many operators. So play packet on the ISS and thanks again for all your efforts!"

Re: QRP re deux
by Michael Heim 20 Dec '08

20 Dec '08

I'd like to weigh in on this topic with my 2 cents worth, being a long time QRP operator on various bands and modes... I think QRP means soething different depending on what kind of operating you do. On HF, its generally 5 watts into a simple antenna, such as a dipole or vertical. HF digital, there isnt much of a distinction (psk31) as many run 5 watts into a dipole vs maybe 20-30 watts into a similar antenna for QRO? I operate VHF and microwave. to me, on 2m SSB tropo, I consider QRP to be 5-10 watts into whatever and however large an array you can muster, as most QRO stations run 50 watts or more into a similar antenna. EME ops typically defines QRP as anything under about 500 watts or so into a single yagi. (no matter how large that single yagi is) Meteor Scatter I've been called QRP running 50 watts into 10 elements. However, on 10 GHz, I run 2 watts into a 18 inch offset fed dish, and I do NOT consider myself QRP. I'm an "average powered station" with that setup. When I ran 200 mW into the same dish, it was questionable even then if I could consider myself QRP. 2 watts = about 2-4KW ERP, 200 mw -= 200-400W ERP. (I havent actually MEASURED the gain, this is calculated ERP) QRP is a relative term. Depending on what kind of operating you do, ERP certainly does take into account whether you're QRP or not. I think in the satellite realm, I would understand QRP to be 5 watts or less into a low gain antenna. Maybe I'm wrong about this, as I'm still a relative newcomer, however This puts everyone on an even keel as far as someone stepping over another to make it fair for everyone. I know there are operators on the main channel that might tweak up the power to get thru on a busy channel. I know, because I have when I started out. I have realised it wasnt right, and now my power stays at 5 watts on the 857. Do i consider myself QRP on AO-51? well, with my homebrew 3 ele/6 ele V/u antenna on a fixed elevation mount, yea, at times I do, when running 5 watts. I actually have LESS antenna gain than someone would have with a handheld yagi because the antenna is hardly ever pointing right at the bird. The QRP channel does provide some interesting experimentation like what Tim, N3TL and others have done, exploring "how low can you go" and still make contact. To me, THAT is the kind of experimentation that seems like a logical purpose for the "QRP" channel. As a side note, hasnt the rule always been to run just enough signal to achieve a downlink of reasonable quality? I remember this from my AO-10 days. Too much power on an SSB bird robs power from everyone. Too much power on an FM bird robs others from getting in.

If you look at it another way. Standing on relatively flat terrain with 5 watts from an HT on a simplex channel will give you a mile or so on FM. That same 5 watts from the same HT at the Empire State Building observation deck will give you coverage to several miles, if not several states. Either of those two scenarios, I consider to be QRP. 73 de W4AS Sebastian On Dec 19, 2008, at 6:49 PM, Jim Danehy wrote: > the premise that I follow is that QRP in the ham fraternity for > decades prior to AMSAT was 5 watts output from the final stage of > the transmitter . . . any other attempt which hopes to replicate > that simplistic approach is speculation based upon a dynamic that is > flawed from lack of accurate measurements . . . and constantly > changing parameters . . > > HAPPY HOLIDAYS > > Jim W9VNE _______________________________________________ Sent via AMSAT-BB(a)amsat.org.
