I am in the same position except I measured it with a multimeter set to 
the AC millivolts range (on Gary Surrency's advice) and the software 
responds with a one time change of frequency and mode (N3FJP ACLOG). My 
question is what in the K2 generates the continuous data stream?

My story is that I think that in a nearby lightning strike, my USB/RS232 
adapter was fried. I also found that my Adapter chip on the I/O board 
needed replacing. In debugging this condition I destroyed the MCU 
(grugh).That's now replaced and I'm at this one shot condition. I 
replaced my damaged adapter, that was working, with the same make (from 
Buxcomm). That works to extent  that it passes on the one shot data. Any 
ideas?
