I recently completed assembling a QMX Mid Band Rev. 4 and had problems getting it to work properly. There was no output on any band, with lowish power drain on all frequencies. I contacted Jeff Moore W1NC and he kindly agreed to have a look at it for me. He expertly gave the set a full overhaul and found several solder wiskers and dry joints (ouch), rewound a couple of the toroids and returned it safely to me in full working order.?
So many thanks to Jeff for his time and help.?
