QMX / QMX+ SSB Firmware - Install & Calibration | HamRadio

A very long video about how to update your QMX(+) to the SSB Firmware and running the calibration sequence. You should run calibration at full supply voltage of your individual QMX(+), but not exceed it. So that is either 9V or 12V, depending which variant you built/got. - !!! So definitely NOT EVER run with 13.8V !!! There have been reports of damaged / fried BS170 HF transistors after calibration. Some people suspect the kickback of some inductor in the transmit chain to cause this. So please understand, that I take no responsibility for any broken / damaged devices. You follow this video tutorial at your own risk! I filmed this on 2nd of May 2025 with the latest official SSB Beta firmware and the official SSB firmware was released on 2nd of May as well 😆. You can find the official firmware under https://qrp-labs.com/qmx.html together with an updated user manual. I still recommend reading the information on the SSB Beta page though! The QRP microphone housing is from scottbaker: https://www.thingiverse.com/thing:477... Good luck and enjoy the hobby! Thanks to LB8VA and MM7HJI for quality control.
