[hpsdr] Using Mercury to monitor final amplifier transmit signal

[Joe Martin K5SO]

Hi Tom, 

Predistortion possibilities aside, it seems to me that operating in duplex mode with the Rx1 freq set to the Tx freq might work for you with a single Mercury.  Take care that the input rf level to Mercury is within safe limits, of course.
