[Elecraft] Psk

[Stephen Prior]

Thanks Julian, that's interesting.  I haven't got to transmitting yet as I
find that I have lost the ssb tx audio somewhere!  I don't even have any
output using the microphone - I think I must have made a mistake on the mic
header where I have soldered the screened cable for the data audio in.

Thanks

73, Stephen G4SJP
