Ed Thanks for your feedback on end to end signal EIRP rules of thumb between JT65 and CW. The frequency stability and other JT65 mode considerations are where I need the trade offs and it's nice to see it can be done with under 10 watts of drive to an amplifier in Class C. That makes it

Not that I know of Bob. After the initial KX1, they brought out the 30m add-on which I have and the 30/80m add-on which I don't have [life at my age isn't long enough for QRP with short antennas on 80m :-)]. Mine is S/N 678 I think, it's buried in my SOTA bag and I don't have time to go look,
