Think I heard COMPASS-1 today?
Today while listening to the clean tones of CO-65, another very warbly CW signal came up right on top of it. I did a quick scan of all other AMSATS and found that Compass was over at the same time.
I notice it is listed as semi-operational. I guess this was one of those Semi's?
Or is it on all the time and I can add it to my list of Demo satellites?

Hi Bob,
Not only is the Compass beacon alive and well with housekeeping information every three minutes but if you care to send it a few DTMF tones when it is sunlit it will respond with beacons, housekeeping data at 4800 etc. DK3WN has decoders on his website.
A typical beacon decode:
Solar Cell Voltage 4.84 V Solar Panel 6 Cur (+Z) 112.94 mA Solar Panel 2 Cur (+Y) 0.00 mA Solar Panel 3 Cur (-X) 0.00 mA Solar Panel 4 Cur (-Y) 0.00 mA Solar Panel 5 Cur (-Z) 43.92 mA EPS Reset Counter 1 Power Level Battery Charging Heater Active Battery Heater OFF Power Safe Counter 2 Emergency Mode Counter 0 Battery Voltage 4.00 V Battery Current 0.00 mA Battery Temperature 7 °C
