Re: No Speaker Audio #ubitx



If you turn up the volume too much the chip heats up.. specially with 4 ohm speaker.
I blew up one non WX chip.

Instead of 12V you can feed the audio chip 9V from a regulator and you will be safe.

I had one without the wx and failed anyway after half an hour. It was marked with an M.

Well that's disappointing, I have the WX branded one.

Is there a cross pin test you would suggest we check to verify?
