[amsat-bb] Re: Photos From ISS via Twitter
Hi Luc: Your question was: Why they don't put the ISS cross band repeater on? Answer: I assume you are referring to the Kenwood TM-D700 radio, when it is in Cross-Band mode. The TM-D700 is a good radio, but it was never designed to support the duty cycle required by a full time Cross-Band repeater on Earth or in Zero Gravity. Even though the radio does have the Cross-band option and the ISS crew has on several occasions placed the radio in Cross band mode, they only do so for short periods of time, when the crew can monitor the radio. One of the primary reasons for only running the TM-D700 in Cross-Band for short times slots is because of the potential for overheating. All electronics on ISS run hotter, because there is NO convection cooling. Earth based Electronics must be modified to compensate for Zero gravity and the loss of convection cooling. The TM-D700 is not immune to overheating. In August 2006 ISS commander Pavel Vinogradov reported the D700 over heated and locked-up when it was left running SSTV all night long. It was during his mission we discovered the problem with the ARISS Vox box was getting stuck transmitting, possibly because of RF getting into the Vox box. During an ARISS telecomm , Sergej Samburov, RV3DR, relayed the gist of the conversation he had with Pavel Vinogradov to myself and the ARISS team in the teleconference. Pavel had to unplug the power cables to the radio and then reconnect the radio, in order to clear the non functioning buttons. We do not know what power setting was used on the D700 during that part of the mission (special modifications limit this radio to 5,10 or 25 watts). What we do know, is that it did over heat and the radio was never quite the same afterwards. A backup TM-D700 was sent to ISS for Richard Garotts Mission. The duty cycle for Cross-Band modes is much higher than those required for unattended packet modes.. While passing over the USA, it is possible for the Cross Band repeater to be active for 20 consecutive minutes with a duty cycle over 50%. In my professional opinion, placing the TM-D700 in unattended Cross Band repeater mode on ISS would not be safe. Marex did propose in 2006 and 2008 ARISS International meetings a Heat sink / Fan upgrade for the TM-D700. ARISS rejected the proposals, stating they did not see any need. http://www..marexmg.org/fileshtml/turbofanproject.html WF1F --- On Fri, 2/5/10, Luc Leblanc luclebla...@videotron.ca wrote: From: Luc Leblanc luclebla...@videotron.ca Subject: [amsat-bb] Re: Photos From ISS via Twitter To: amsat-bb@amsat.org Cc: sa...@amsat-bb.mail03.videotron.ca, eu-am...@yahoogroups.com Date: Friday, February 5, 2010, 1:10 PM On 5 Feb 2010 at 9:35, Clint Bradford wrote: Date sent: Fri, 05 Feb 2010 09:35:39 -0800 From: Clint Bradford clintbradf...@mac.com Subject: [amsat-bb] Photos From ISS via Twitter To: AMSAT BB amsat...@amsat..org Last month we received the first Twit from space.

[amsat-bb] Sounds from Space
Dear AMSAT fellows, recently I got some additional interesting information and pictures especially on the early AMSAT satellites and added them to the Sounds from Space collection at www.dd1us.de. Please have a look and hopefully enjoy it. I am still missing any recordings of the early AMSAT satellites AO-II to AO-5 and would kindly ask you to double check (maybe also with some older Hams which are not participating in this group) whether they might still have such documents. I bought an old tape recorder in order to be able to digitize also older tapes. Many thanks in advance for any help. Best regards 5573 Matthias www.dd1us.de ___ Sent via amsat...@amsat.org.

[amsat-bb] China Ham Radio-Shanghai 2010
Hi AMSATs, I wonder if there is any satellite organisation or satellite (cubesat)group with a booth at the China Ham Radio in Shanghai (3-5 April) ? My plan is to be there to present my small linear transponder design like I did at the Tokyo Ham Fair. However, the booths are quiet big (3m x 3m / 10ft x 10ft) to present my small linear transponder. I can not take to many hardware with me on the plane. Maybe there are more people interrested to have a small booth space at the China Ham 2010. Because of that I am looking for people who like to share the booth with me to promote ham radio projects, preferable related to amateur satellite projects.

[amsat-bb] Re: AlfaSpid RAS Predict
Hi Ryan, At first I ran my Alfa Spid off the shack 13.8V D.C. supply. I also got flicker plus some anomalous readings. I put this down to voltage drops on my power supply. You might be having a similar experience as under load from the Spid motors your car battery may not be giving 12 volts. Here is my solution. The Spid will run on AC as well as DC so I got a largeish mains to 24V toroidal transformer. Put it in a box with the usual connectors, fuse, switch etc. With my Spid on a dedicated supply it works perfectly. Didn't cost much and is fully independant of the radio supply. I think the Spid Alpha system is an excellent piece of kit, mechanically probably overkill for most satellite antenna installation but I expect mine to last many times longer that the alternatives. If you didn't get the mouse option its great.

After long eclipse periods caused a negative power budget on FO-29 in early November, 2009 which took it off the air temp- orarily the command team switched the satellite from continuous operation to scheduled operations. This allows the command team to monitor the state of the battery charge aboard the spacecraft and adjust operations as required. Since the last commanded power up of the analog transponder on January 27, 2010 the command team has received reports worldwide which indicate that FO-29 has been able maintain continuos oper- ation. The power budget aboard the spacecraft is improving as the eclipse periods decrease. If the power budget decreases too much the satellite will auto- matically power down. The JARL command team requests telemetry reports (either direct or posted via the amsat-bb) from stations that may have data from January 27 to January 28. Additionally, if you find the transponder is off during a scheduled ON period please report this to the command team as well. JARL places no restrictions on the use of FO-29 during scheduled operation periods except to remind satellite ground stations to transmit with as low as uplink transmitter power as possible.

I have seen the ones from funkbox (Winrotor USB interface) and the one from EA4TX, but I need your opinios, which you consider the best? The winrotor is usb and the ea4tx is to plug in the pararell port without any box.I prefer the usb but I don't know, to be honest, which is the best and more compatible.please, any light is welcome.

[amsat-bb] Endeavour Set - 1:39AM PST
Endeavour is scheduled to launch very early on Sunday morning - on what will be the first of a final five planned shuttle missions before the shuttle program is retired. CNN begins live coverage at 4:30AM Eastern for the anticipated 4:39AM launch. And NASA TV, of course, is running now. Clint, K6LCS ___ Sent via amsat...@amsat.org.

[amsat-bb] LVB
And G6LVB said: Yes, I can vouch for it being rather good too. 73, Howard G6LVB I never thought that watching an AO-40 demo in the parking lot of the Dayton Hamvention could be informative but also humorous. I remember it very well, and it's good to know you still have that humor. It's good to hear from you. All the best from Indiana. Mike K9QHO ___ Sent via amsat...@amsat.org.

[amsat-bb] LVB Tracker and Kenpro
Thanks to all who answered my (incomplete) email. It is clear to me now that my Kenpro 5400-A, which has an external control on the back, can be made to work with the LVB tracker. After the 2 feet of snow melts, I will be refurbishing the rotator where needed. I am hoping this and the antenna deployment coincides with the arrival of my U/V full duplex 60w on both bands, transverter block arrives from Flex and I get back on satellites again. 73's to all and thanks again for the answers.

[amsat-bb] Re: 20-year Li-Ion Packs
Jon Bloom and the ARRL labs did a great job with the BCR. While we are no longer optimizing the set point for maximum power transfer, the batteries do appear to have been a very good choice and the BCR and solar panels are working in those which are still talkative. The South Atlantic anomaly appears to be the death bringer. I personally no longer fear batteries as the likely failure mode over the reasonable lifetime of our satellites when designed by someone who knows what they are doing. What these lithiums offer us is much great energy density than we can get with NiCad chemistry. Now it appears the first shots have been fired in making them last a long time. What we don't know yet is how structurally sound these new cells with increased lifetime will be. What will temperature cycling and vacuum do to them, etc. I hope that this progresses and ends any and all speculation about the wasted effort (my view alone) on capacitors which do not seem to be approaching the energy density of bad batteries. The density curves with caps is looking pretty asymptotic to me. A big leap is needed to make them competitive. Bob N4HY On 2/5/2010 7:04 PM, Mark L.
