I've never had much luck with the "enamel will burn off when soldering" approach. Sometimes it works but just as often it doesn't. I always scrape with a razor blade and give it a few swipes with a

I would like the bandchanges differently.? Now it is painfull to hop between bands. Going from 15 m to 10 m and then back makes it a lot of double clicks and eventually shuting down the QMX + when

It's worth watching the earlier parts of Mike's video as well. The rattlesnake he encounters on the way to his park activation is beautiful! -- MC VK1MC [email protected]> wrote:

It is really easy. Just connect an USB-cable between your QMX and PC. An soundcard (QMX-soundcard) and new COM-port are added automatically. In VARA you choose the QMX-soundcard for input and output.

Thanks Mustafa TA2MUN for sharing this one with me! The enthusiasm is so infections, might even get ME on SSB eventually! https://youtu.be/P09N-t1U1-E?si=xLUi5bMmboDOEnrL&t=396 73 Hans

An 'open' in the LPF (not just a short) may also cause this problem, and is a common assembly issue.? ?Does the LPF sweep for 12m in the Hardware tests give a proper response?

The QMX does not have an internal mic preamp circuit,? so a low-sensitivity -50dB mic element will perform poorly.? ?When you turn up the mic gain enough to get a proper amplitude,? the noise will

Yes, you can run T (TX) from diagnostics screen. SWR doesn't mean anything if there's no output power. I had a bad joint at the L502 (which all output goes through) and after fixing that, saw 3-5W on

Could you share your settings with us? ?Where did audio output from QMX go? ?Are you using VOX for input? ?Any help would be much appreciated.

I second what Richard says. Some QMX/QMX+ units fail to independently restart at the beginning of the firmware update process, and also sometimes after the firmware is loaded.? Just power it on

Yes, I had the same thought. At any rate, whatever transistor is in there, I don't think the glitches are doing any good. Tony AD0VC ________________________________ Sent: Monday, May 5, 2025 7:09

In Windows my QMX+ shuts off, then I power it back up and it appears as a window/drive. I then drag and drop the new file into that window and when it finishes the qmx+ boots up.

If you want someone to test/repair it for you, the one to contact is Jeff, W1NC.? ?His email is good on qrz.com If you are handy with a multimeter and soldering iron, we can try to help you

This is my approach, I insert? my QRP-O-METER after the radio and switch in its bridge when running the tuner. 73, Don N2VGU

Mike, using the external bridge will certainly work, and give an independent evaluation of swr. I use the QMX+ Hardware test -> Tune SWR function to tune the ATU.? At the reduced power there isn't

TNX. Adventure radio and excellent report. ?????

On 4/29/25 I had a CW practice / rag chew session on 17 meters. I worked four stations: Conditions were OK with some QSB. SSN = 134, SFI = 154, A = 4, K = 1. My next CW practice session will be

Sorry if I missed it, but what precautions should one take when running the ATU? As far as I can tell the QMX+ will see every impedance that the ATU hits while doing its search. Once Hans gives us
