My 20m QCX+ is working quite happily albeit only on receive so far. I have been measuring the output with a scope across the QRP Labs Dummy load and with a 12 V supply I am seeing 23.2V peak-to-peak, which I calculate at 1.3W. At 16V supply this rises to 31.2V or 2.4W. I don't know if it is relevant but the supply current goes from 450mA at 12V to 580mA at 16V.
This is somewhat lower than expected, any suggestions gratefully received.
