I did a little video yesterday. If you are interested in knowing a bit about AO-91's receive capability and some of the fun we had getting her to the launch pad, here is the URL. https://youtu.be/no4pHx02lSI -- Jerry Buxton, NØJY

ISS SSTV
by Andreas Kellner 07 Dec '17

07 Dec '17

Received 2 beautiful clear pictures (12/12 and 1/12) from ISS SSTV on a 62 degree pass over east coast Australia. Very strong signal .. never heard the ISS that strong ? Transmitting in the typical 3 min on / 3 min off schedule. Does anybody know if they issue certificates again on this SSTV cycle ? Thanks, Andreas - VK4TH

Hello John, I am not sure if my email when to junk. Since Yuri is coming to New Orleans, I can help with free LMR 400 and connectors if he still needs it?? 73 de Angelo / N5UXT in New Orleans.

Instructions are at papays.com/sat There are no changes from the original procedure. The Seahorse is a relatively new ship and is wider than previous vessels so it cannot go through the locks in the Great Lakes. So he will be more restricted as to possible destinations than he was last season. He has been very busy with his duties and has had little time for anything else.
