Another QRP Labs Radio Saved by W1NC
Jeff did a great job saving my QCX+ 40M radio after I messed up the T1
coil and how it was soldered in.
I sent him the radio and he had it diagnosed and back to me in less than a

Re: Display Problem With Newly Constructed QMX+

Hudson, no switch on without the 5V SMPS board (see schematics page 1 and QMX QMX_plus Startup ( /g/QRPLabs/wiki/36878 ) section 2).

Re: A QCX++ ?
I think Han's 'wizard' idea is great, I can turn off the CW functionality and just keep the digital/ssb modes. Perfect!!!

Re: QMX 3d printed cover
Perhaps small tabs at the corners, outside current shell, stop the slipping.

I built a midband QMX a couple months ago; it worked fine for a solid handful of QSOs and many hours of use in code practice mode.
I was in the process of testing a newly built manual antenna tuner.

Re: QDX is dead. USB interface nonfunctional. Flummoxed. Help, please.
Hi Jim,
