[Elecraft] KX3 PBT on SSB

[Dana Browne AD5VC]

I am simply taking the headphone audio output (not the I/Q output) and running it into Digipan or Fldigi.    This radio is just the stock radio with no added KXFL3 filter.  I just wanted to experiment with sound card audio on the KX3 and used the method that has worked with other radios.

I had not heard of the other demodulation scheme before.  I guess I have some more reading to do.

I will try the Data A mode.  Thanks for the feedback, folks.
