NOTE: CW section is subtitled with Closed Captioning (CC)! Turn on closed captioning to see the translation, or practice your head copy with it off.
Ever since I built my high-band QMX, it's been unusable for CW due to a strong 'thunk' at the end of every CW dit and dah. Frustrating, but I had faith that Hans of QRP Labs would figure out a clever firmware fix. Well, I'm happy to report... he's done it! Version 18 of the QMX firmware works like a champ, and bans the 'thunk'.
Audio in this video is recorded straight out of the QMX using a Y-splitter, so what you hear is what I was hearing in my 'cans'.
Location: Kagel Mountain, W6/CT-170
Activation date: May 4, 2024

It is maybe the best QRP rig on the market right now. You will love it I am sure… Ultra compact 5-bander with capability to operate from 8-13.8V, SWR meter included. The price is still very reasonable and radio looks professional. Congrats to Hans!

Another great video! Can't wait to get our QMX-mini. Until then, we love our QCX-mini. Well done on the closed captions so that folks can turn it on or off. Did you have to hand create those? What mic do you use to record the CW? We have DJI mics and when we plug them into the QCX-mini, it won't transmit.

Sounds good. Would you be willing to post your AGC settings in the description? Your QMX sounds a bit better than mine does.

I'm using the settings shared by Steve K1RF on March 3rd, 2024, to the QRP Labs mailing list. His settings are: AGC - ON Threshold S - 7 Slope dB per dB - 60 Noise filter - 5 Hang time - 30 Smooth samples - 50 Recovery dB/s - 50 Sample blocks - 4 S9 sounds like S - 9 AGC display - ON AGC dB per bar - 3

Great news, Thank you. Are clicks during transmit in this video related to antenna? I mean that your antenna too close to rig and your headphones and power cable can receive your signal during transmition and as a result you hear interference as clicks. Working antenna like this (very close to headphones) I bourn out FST in my QCX. Hopefully this was an easy to replace.

I've checked against a dummy load, and that's just kinda what it sounds like - no relation to RF messing with the electronics from a poor match.
