Re: Trying to understand differential heating issues of PA Fets in QCX40

Running the QCX40 as a WSPR beacon overnight at a feeble 7.5 volts still brings in some good spots. The Antarctic and Australian spots were around -25 to -27db with one at -32db snr out of the five spots. The receiving sites are of course both in a very low noise environment to be fair, so they are doing most of the work at the receiving end.

Still a nice sight to wake up to in the morning.
