Finally managed an Arrisat-1 real time telemetry decode!
I'm excited! A few minutes ago on the ARISSat-1 pass over New Hampshire (US) I received it nice and strong (as usual) got the doppler correction running on SDR-Radio (have done that before), and with a newly-built computer in my shack finally had enough processing power to deal with SDR-Radio, Virtual Audio Cable, AND the ARISSat telemetry decoder, so I got some actual real time telemetry. Just in time for the "last telemetry frame" contest, I'm afraid :-)
Was anyone hitting the repeater around 20:20 UTC today? I was not listening, but watching on the waterfall display of SDR-Radio. The telemetry and the FM digitalker were very clear...not sure if there was anything in between...I saw a few smudges that might have been modulation...

Hello Burns,
Very good on your reception in New Hampshire. I was calling W4HTB and W8RVH who were trying to find me with my receiver fixed on 145.930 for the 20:16Z pass over Cincinnati. I was able to hear my downlink for about a minute before ARISSat-1/RADIOSKAF-V reached Max El then lost it for a while as my Tx antenna had no El control. I picked it up near the end of the pass and heard fairly strong CW near my Rx freq. From the variation I observe I believe the satellite is in a slight tumble as the 145.930 MHz reception goes very weak then builds, sometimes rapidly.. I was fortunate to get an SSTV picture through the transponder on Nov 12 when by chance I managed to get lined up with the short antenna on the 70 cm receiver to transmit an R36 picture.. I may try SSTV again if signals warrant. I hope others will keep trying CW, voice or SSTV. I do observe that the signals seem to be stronger at the sats lower altitude.
