Re: QMX Questions
I am guessing that there is an interrupt that is not being serviced in a timely manner but having never seen the code, I can only guess.

LOW POWER OUT.
I built my QMX for 9 volts.
After the L401 jumper mod I kept the original number of turns and spread them out as much as possible.
The receive has improved but the transmit power is well below what

Very good Mike, that helps a lot. This is my first QRP Labs radio so I was a bit lost.

QMX Receive Optimizing--Navigating the QMX
I've been following the discussions about improving the QMX receive sensitivity, and I have no problem admitting it's way beyond my comfort level.
