It could well be that someone associated with AMSAT developed a self-deploying antenna. The ones used on Alouette 1 were first rolled up inside the main body of the spacecraft and then rolled out with on-board motors. 73s Bernhard VA6BMJ @ DO3FL snip ___ Sent via AMSAT-BB@amsat.org.

Regarding Canada's Space Program, did you know that Canada's oldie satellite Allouette-2 is back to live???, or at least its transmitters. While I was monitoring the 136-138 satellite sub-band a couple of months ago with a RTL2832U based cheap SDR dongle I founded weird doppler shifted signals not matching any known transmitting satellite. After reporting it on the HearSat mailing list and posterior confirmation from Mike Kenny in Australia the best match was Canadian old satellite Allouete-2 launched in 1965. It is amazing how solar panels, antennas and transmitters stages are functioning after 48 years!!! It can be heard on: 136.076 +- 2 KHz with high instability, strong. 136.589 with unmodulated sub-carriers, weak. 136.981 Continuos Wave. All three transmitters are alive after many years. It seems that due to some unknown reason it started to transmit again. May be the very same UFO which un-plug the batteries from the AO-07 bus ran across that oldie historical satellite and push the ON button HI HI HI HI HI!!!

Nope, It was only announced on the HearSat mailing list and only few enthusiastics replied. On this world of new space probes with S band downlinks very few are interested in monitoring old birds which comes back to live spontaneously. However the happiness and enjoy I felt after re-discover that old historical spacecraft is beyond compare It is like space archeology An U.S. ham re-discovered LES-1 several months ago and some media wrote a news report, but the original owner/builder of the satellite didn't reply to his e-mail About Allouette-2, the interesting was the international collaboration, Cuba and Australia are almost in opposites part of the world, but Mike Kenny and I still exchange information and collaboreted for confirm the re-discovery, and that my friend is the true ham spirit 73, Raydel, CM2ESP - Original Message - From: B J va6...@gmail.com To: Raydel Abreu Espinet (CM2ESP) cm2...@frcuba.co.cu Cc: AMSAT-BB@amsat.org amsat-bb@amsat.org Sent: Saturday, September 28, 2013 10:17 AM Subject: Re: [amsat-bb] Re: CASSIOPE's Foldable Antennas On 9/28/13, Raydel Abreu Espinet (CM2ESP) cm2...@frcuba.co.cu wrote: Regarding Canada's Space Program, did you know that Canada's oldie satellite Allouette-2 is back to live???, or at least its transmitters.

[amsat-bb] Re: CASSIOPE's Foldable Antennas
Hi Bernhard and all, I guess you are looking into the wrong catalogue number. Allouette-2 is 1965-098-A, not L which is what you looked for. I download its TLE regularly from Space-Track. NORAD Number is 01804. The TLE I am sending you is from 4 days ago are still good, in a previous e-mail I sent the frequencies: 0 ALOUETTE 2 1 01804U 65098A 13267.80431926 .0325 0-0 11085-3 0 4491 2 01804 079.8011 254.0639 1347527 258.0698 086.6578 12.24267898109332 Mike Kenny has a nice page with old ages and historical 136-138 MHz band emitters. I don't remember the address, but you can Google it. By the way, my apologize to the rest of the AMSAT-BB readers, as it is not a 100% ham sat topic 73, Raydel, CM2ESP - Original Message - From: B J va6...@gmail.com To: Raydel Abreu Espinet (CM2ESP) cm2...@frcuba.co.cu Cc: AMSAT-BB@amsat.org amsat-bb@amsat.org Sent: Saturday, September 28, 2013 9:29 PM Subject: Re: [amsat-bb] Re: CASSIOPE's Foldable Antennas On 9/28/13, Raydel Abreu Espinet (CM2ESP) cm2...@frcuba.co.cu wrote: Regarding Canada's Space Program, did you know that Canada's oldie satellite Allouette-2 is back to live???, or at least its transmitters.

I gathered what I found before was information about Alouette 2's debris, which I assumed was referring to an inactive satellite. There's also an entry for 1965-098K, which is also debris. The correct URLs for Alouette 2 would be: http://n2yo.com/satellite/?s=1804 http://nssdc.gsfc.nasa.gov/nmc/masterCatalog.do?sc=1965-098A There's more information on Alouette 2 at: http://astronautix.com/craft/alouette.htm Also, I found these links to be useful: http://planet4589.org/space/space.html http://planet4589.org/space/log/launch.html http://planet4589.org/space/log/satcat.txt By the way, your comments prompted me to look up the HearSat mailing list and I signed up for it earlier this evening. Thanks for the tip. Now I have another way to have fun with satellites! Perhaps listening for old satellites might be a suitable topic for a Journal article. 73s Bernhard VA6BMJ @ DO33FL ___ Sent via AMSAT-BB@amsat.org. Opinions expressed are those of the author.
