Mission Time: 006607 minutes
Temperature: 12 degrees celsius
Battery Voltage: 26.(?) volts

Voltage seems to be good remain not too much to investigate. Is it possible 
what we received is coming from a disconnected coax at the antenna end? or a 
broken antenna at the feed point?

You can do your own test a standard scanner can copy a signal with a 2 feet 
coax connected without any antenna. At low or high power!
