ARRISat-1/RADIOSKAF-V/KEDR
by Farrell Winder 28 Nov '11

28 Nov '11

All, With the research and recent "heads up" by Mineo Wakita, JE9PEL, Allan Biddle, WA4SCA and Clint Bradford, KCLCS it appears there may be only a few weeks left to receive and experiment with ARISSat-1/RADIOSKAF-V. 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. I will be listening and looking for others to send also. Farrell Winder, W8ZCF Cincinnati, Ohio.

>> ... Some peoples kids I swear ... I guess you've never lost a "friend" after a seven-years-or-more relationship ... Yes, those who pay attention "knew" this day was coming. Shame on you, though, for demeaning the passing of what has been a brilliant marketing and public relations and educational tool for the benefit of amateur radio across the planet.

AO-51 frequency
by Ollie Eisman 27 Nov '11

27 Nov '11

Given the current problems with AO-51, should we be listening for a signal on 435.150 Mhz? Could another downlink, such as 435.300 MHz, get switched on randomly? 73, Ollie AJ1O

>> ... nothing heard here - Kevin KF7MYK Thanks to the three folks in my Skype conference ... and another three texting me on my phone, and to Kevin and others with email messages ... Nope - darn it - nothing heard on what has - for the past 6+ years - been a great pass of AO-51. Clint, K6LCS

AO-51 2:31PM PST 11/27/11
by Clint Bradford 27 Nov '11

27 Nov '11

A great pass of AO-51 at 2:31PM PST over Southern California - and the West Coast of the U.S. ... Anyone else going to monitor/work it? I'll be online on Skype - Skype name is ... clintbradford And I'll have my cell phone outside - 909-241-7666. It is a great, middle-of-the-day pass ... If being illuminated by the Sun "makes" it happen, this is an ideal orbit ... Fingers crossed, Clint

Last chances to hear ARISSat-1 are rapidly approaching.
by Alan P. Biddle 27 Nov '11

27 Nov '11

All, A reminder that if you have been putting off working through the ARISSat-1 repeater, receiving SSTV pictures, or submitting telemetry, the next few weeks will be your last opportunity to be a part of this satellite's history. Since deployment in August, ARISSat-1 has descended about 60 km, and is currently losing more than 1.5 km per day. The rapid rate is partially the result of the recent solar activity on the atmosphere, significantly increasing the drag. The predictions by several individuals and groups are all converging toward a reentry in January or February, 2012. Heating will become significant before then. Remember, good telemetry in this period provides invaluable information to the engineering team, to be used in future projects. The orbit period changes about 30 seconds per day, and that will increase steadily. Be certain to update your tracking program Keps from Space-Track or CelesTrak before each pass. They issue revised versions 3-5 times daily. As the descent continues, this will become even more critical to copying the telemetry beacon, especially unattended. 73s, Alan WA4SCA

AO-51 now shutting off tx soon after eclipse
by Richard Grabotin 27 Nov '11

27 Nov '11

Re-post from Amsat's twitter: "AO-51 now shutting off tx soon after eclipse, due to batt voltage dropping below regulator threshold. Recovers to 1w in sun." Were people still using this bird in eclipse with only 2 out of 6 usable cells? Perhaps this bird needs to be put on a schedule like AO-27. Can that be done? Richard K7LWV
