Good thing you didn't transmit, that would have given you something.
Something like smoke and flames where Q13 and R141 used to be on your Bitx40.
Just in case others decide to replicate your experiment.
Not a good idea to run these rigs with much more than 12v.
(Finals are fine to 24v if you give them an adequate heatsink.)

B40, nothing. I accidently gave mine 20+ when a regulator shorted in the worst possibly way. No damage done. With that audio chip I'll be using a much better regulator! Although I may replace it before I power it up. Then I can run a couple of experiments on the original.
