Finaly got the time to look at my very dead qmx+ Started measuring tantal capacitors ESR on VDD line. All but one showed up ok around 50ohm, except c433 on vdd line for PCM1804 which showed

Can you use electrical tape?

Is the QCX+ Development board the same as the QMX + Development board ? Paul K2DB

The tape on the encoder was the first thing I looked at, but it's possible that a short occurred somewhere else as a result of the vibration of pushing the headphones in. I'll have to take a really

Yes, I put the insulating tape on the encoder. It's still intact. -- 73, Dan - W2DLC

Roy, On a serious note. I use a small soldering station from Amazon the didn't break the budget. I only use Kessler 44 solder and have never had a problem with flow or cold solder joints....I use 760

Yep? Troubleshoot lack of power on should take you to whats gone wrong.? When you know try and figure out how you might be able to make that happen mechanically? . .
