[amsat-bb] AO-51 end of mission
AO-51 will be remebered to me as I am sure some of those great old birds were for the ones that have been around long enough... I hope that one day I will be able to talk on something of that caliber from the stories I hear. Anyway I always enjoyed every contact and sure miss stayin up all night to catch the early bird!

[amsat-bb] Re: AO-51 end of mission
Dear Friends, It is really a sad news. Bidding a farewell to AO-51 with a very heavy heart. Looking at the success, we all at Upagrah Amateur Radio Club VU2URC at ISRO Satellite Centre and AMSAT-India express our heartfelt and sincere thanks, appreciations and compliments to the entire AO-51 (ECHO) team. The AO-51 mission is accomplished with a great and complete success. AO-51 was truly one of the best amateur radio satellites. It was a very favorite for many of our VU hams for its strong signals and ease of operations. we really enjoyed on being AO 51 very long time and it is really hard to bid a farewell to this wonderful bird. 'Thank you AO-51 for your great and fruitful services to the World of Amateur Radio'. Our congratulations to the entire control & command team for their extra-ordinary efforts and incredible technical competence exhibited in keeping up this 'Cute Little Boy' healthy & alive in orbit for such a long period of time. We take this opportunity to thank each & every one associated with this great project and wish AMSAT-NA all the success in their future endeavors. We at Upagrah Amateur Radio Club VU2URC at ISRO Satellite Centre and AMSAT-India assure all the possible and best help for the common cause of Amateur Radio. 73 es good wishes for a 'Happy Christmas & New Year'.

The last telemetry data indicated that the third of six batteries was approaching failure to short, and observations indicate the voltage from three cells is insufficient to power the UHF transmitters. The IHU may continue to be operative. Initial tests with the S band transmitter were also not positive, although more attempts are in order. We have tried leaving the satellite in an expected state where if voltages climb high enough, the 435.150 transmitter may possibly be heard. The command team will regularly attempt communications with the satellite over the coming months (and years). There is always the possibility that a cell will open and we could once again talk to our friend while illuminated. Thanks to all who helped fund, design, build, launch, command, and operate AO-51. It's 7 year mission has been extraordinary. Please support AMSAT's Fox-1 project, and other AMSAT projects worldwide with your time and money.

[amsat-bb] Re: FASTRAC Digipeating Announcement
Or if you have access to a message-capable APRS station, simply send an APRS message to FAST1 or FAST2. The message content can be anything and you must have recently transmitted a position for your station. You will receive a response describing the next expected pass of the respective satellite. Lynn (D) - KJ4ERJ - Author of APRSISCE for Windows Mobile and Win32 PS. You can send a message to ISS or any of the other popular amateur radio satellites to receive the next pass information for that satellite at your most recently transmitted coordinates. PPS. If the body of the message is an active APRS station (callsign-SSID), then the pass prediction will be based on that station's most recent position instead of your own.

Hi John, G4DMF To mount the down convertor at the aerial/masthead seems to be a good solution to way out of range from the TS-2000 but to transmit in 70 cm using the same antenna you need in addition a good coax relay antenna mounted. The relay common port must be connected to the 70 cm antenna and the normally closed contact NC must be connected to the 70 cm transmission line while the normally open NO contact must be connected to the converter RF input. With the above configuration to receive 70 cm using your converter you need only to excite the relay coil. 73" de i8CVS Domenico ___ Sent via AMSAT-BB@amsat.org.

[amsat-bb] Grid activations DM82-83, DM92-93
Next week I will be traveling to West Texas grids DM82-83 and DM92-93. I will probably activate other grids as pass times and my business travel allow. Some have expressed interest in me activating DM73 and there exists a possibility of a convenient DM73/83 grid line pass. Please email me If you need any of these grids confirmed and I will work with you to make it happen. I'm able to work AO-27, SO-50, and the ISS digipeater easily from my portable setup. I realize that these satellites don't have the capability of a telephone-quality call to Italy but these satellites are very convenient to mobile operators and those seeking grids for awards purposes. 73 Clayton W5PFG ___ Sent via AMSAT-BB@amsat.org.

[amsat-bb] Received from shadow experiment
CURRENT INFORMATION ON 02-05.11.2011 SERIES OF SPASE EXPERIMENT “SHADOW-BEACON” Dear friends! It was earlier announced that timetable of SpEx “Shadow-beacon” sessions on November 26-27 -2011 was reduced because the crew is newcomers and need much time to assimilate the experience. For the same reason earlier announced sessions on December 02-05 -2011 are cancelled all. Sergey Samburov (RV3DR), the employee of space-rocket corporation "Energia" which is responsible for an amateur radio on ISS, explains that an observed fact that the onboard radio “Sputnik” was accidentally switched on standard simplex 145.825 MHz not the ordered duplex 144.36/ 145.825 MHz digipeater mode because of old age of the onboard gear- it is in use more than 10 years. Some times Sergey has already observed malfunction like this. New radio are to be delivered onboard ISS by April cargo vehicle and Mission Control Center (TsUP) plans new SpEx “Shadow-beacon” sessions on May-June 2012. With this reason you are asked not to delete your registration on our site. Again many thanks for those submitted reports and made other assistance! The results of data processing will be presented on our site. We wait for further cooperation! --- 73 de andy g0sfj ___ Sent via AMSAT-BB@amsat.org. Opinions expressed are those of the author.

Has anyone other than KD8KSN had success getting grids confirmed? Back in the end of July I had a couple of successful emails with Yuri's qsl manager giving me details on what to send, I provided a list of all QSOs in an email along with sending a list along with a QSL card and some $ for return postage. It has been four months since sending all the info and nothing, not even a response to my 4 emails asking if info had been received. It would be nice to get those 31 grids confirmed.

[amsat-bb] FASTRAC Digipeating Announcement
All, The FASTRAC satellites have been in operation for more than a year and the team has been able to get a lot of data from them, in great part due to the amazing support from the amateur radio community. Over the last month the team noticed that one of FASTRAC-1’s on board microcontrollers which controls one of the experiments has not been booting up correctly. The team has done everything possible to correct this issue apart from turning it off which can only happen if the batteries fall below an specific charge level. Since the satellites have been power positive throughout this whole year the only way this can happen is if the satellites transmit more often. Given that one of FASTRAC goals has always been to eventually provide a platform for amateur radio enthusiasts to use after the primary mission was over, the team has decided to open up FASTRAC-1 to the amateur radio community with the hope as more people use it to digipeat through the satellite, the battery levels will diminish and cause a hard reset of the microcontrollers on board. The satellite will be configured so that amateur radio operators can use it beginning on Friday Dec 2 at 10:00 AM CST. Starting on this date people will be able to digipeat through the satellites. The call sign and frequencies of the satellite are summarized below and an example of digipeating through the satellite is also shown in below. To increase the chances of causing a hard reset, it is requested that as many amateur radio enthusiasts try to digipeat through the satellite on the weekend of Dec 10. If you are successful at digipeating through the satellites or have any problems doing so please let us know at fastracs...@gmail.com, through our Facebook page ( www.facebook.com/fastracsats) or through the forums on our website ( http://fastrac.ae.utexas.edu/for_radio_operators/users/phpBB3/index.php). *Frequency Information for FASTRAC-1* - FASTRAC-1 “Sara Lily” Downlink Frequency: 437.345 MHz - FASTRAC-1 “Sara Lily” Uplink Frequency (1200 or 9600 baud): 145.825 MHz - FASTRAC-1 “Sara Lily” Satellite Call Sign: FAST1 *Example of Digipeating through FAST1 * - cmd: c CALLSIGN via fast1 - cmd: KE5DTW>CALLSIGN,FAST1/1: <>: - CALLSIGN>KE5DTW,FAST1*/1: : - *** CONNECTED to CALLSIGN VIA FAST1 Here the example shows KE5DTW (UT Austin Ground Station) digipeating through FAST1 to connect to CALLSIGN.

[amsat-bb] Fw: ARRISat-1/RADIOSKAF-V/KEDR
All, Nothing heard from ARISSat-1 this AM Dec 1 during the 13:59 Z Cincinnati pass, too close to the eclipse. Depending on updated Keps will be checking mid Dec for renewed opportunities. In the meantime, I hope many stations in other areas will keep trying to get SSTV through the TRANSPONDER. Henk, PA3GUO , the Netherlands and I were successful with a picture . (See http://ariss-sstv.blogspot.com/) We need other SSTV images from this historical satellite before it re-enters. Thanks to all those making efforts. 73, Farrell Winder, W8ZCF Cincinnati, Ohio, USA From: Farrell Winder Sent: Wednesday, November 30, 2011 7:20 PM To: AMSAT Subject: Fw: ARRISat-1/RADIOSKAF-V/KEDR Again nothing heard from ARISSAT-1 on the Nov 30 13:43 Z pass. I will be observing the 13:59 Cincinnati pass on Thursday Dec 1. I believe it may be out of eclipse long enough to be active. If so, I will be listening, looking on 145.930 and trying to send SSTV, on 435.750. Hope many others will also try. Tx and Rx of SSTV has been demonstrated a couple of times through the Transponder even with its shortened antenna and I believe with persistence can be done again. This is the last, possible active, useable pass for my area until mid December. I will be back Dec 18 if ARISSat-1 is still in orbit. Please report any thing received Dec 1.

On Monday Nov 28 I will be set up to receive voice, CW and SSTV via the transponder on 145.930 MHz +/- doppler. This will be on the AOS starting at 14:47 Z pass over Cincinnati. This pass may be too soon after the eclipse so the sat may not be activated. If it is active, I will try to send a couple of SSTV R36 transmissions.
