Hello all.
I bought a built QMX, being in my early 80s and not quite up to building a complex QRP Labs kit. When it arrived, I unpacked it and plugged in the PS IO use for the K3. Looking at the panel, I saw the blinking battery symbol and after some rtfming, plugged in a 12 VDC PS. However, the QMX+ has major problems, some as quirky as a sidetone which is sometimes there, sometimes not, and major problems such as it does not receive or transmit any RF energy (and it’s not in practice mode). Would ten seconds of 13.8 volts cause this amount of disfunction?
Thanks,
Dave K9SW
