I have good luck with my ZM-2 ATU. Google EMTECH... they come as a kit or pre-built. Jerry WB7S LICW/SKCC/CWOpp -- This email has been checked for viruses by AVG antivirus software. www.avg.com

Hi, I tried to use a standard Baofeng micro , the one with a small loudspeaker inside that is not usable with QMX. I have done the easy mods to make possible using this mike with the QMX. No a big

1_01_004 - menu item history fix would be very helpful With the addition of new items under 'Hardware tests' in the menu, we can now no longer just click twice on the menu button to get to the Tune

Awesome! Thank you! -- 73 Michael N6QP Up in Thin R

How do you get to Tune/SWR mode? I don't find it in the manual. -- 73 Michael N6QP Up in Thin R

Nice! QMX to QMX. That’s cool.

Did you try tuning using the Tune/SWR mode?? In that mode, QMX uses reduced power and turns off the swr protection. That may work with your LDG tuner.

Is there a manual tuner that ppl use with the QMX+ - I tried using my LDG Z817 and it seems to go into protective mode for final. too high swr. Im too old to build and am looking for something retail

I took my QMX to Mt. Porepunkah in North Eastern Victoria for some SOTA and worked another QMX on the North Island of New Zealand on 20m (ZL1HIM). Clear audio both ways. Cheers Glenn VK3YY.

Yes, what Ludwig recommends is important.? A failed Q508 could be the cause of the problems, with D516 being the trigger. Here is one theory of what happened: a) With D516 either not connected, or

You should check Q508 in RX and TX mode (voltage at S, D and G). To cut the high current lift a leg of L502. A broken Q508 could be a dangerous load for the PA and may affect the RX path. 73 Ludwig

One thing I have seen is that windows will install a new physical com port with the same port number as a virtual port I have defined with vspMgr. My solution was to delete the virtual port with

Thanks for your warning Ian. Don't worry, why should I connect my field operation computer to the internet? In my life I had to deal with at least 13 OS and version of OS (not only MS). It took me a

Interesting. I am running the same OS build here with no USB related issues on my QMX+. I have been running two COM ports to the QMX+ for the past several hours without a

Thank you, Tobias. Makes me feel a bit better not being in left field, alone. 73 Dick, K5AND Sent: Thursday, April 24, 2025 3:47 PM To: [email protected] Subject: Re: [QRPLabs] #qmx SSB Firmware

Immediately after the firmware update, I ran PA mod. test: And then attempt to run DAC error vs phase on 20m.? It generated an error that would not let me run the test like what is noted in the

Aha, many thanks for this. i can’t really test that or look in the menus at the moment as the draw when powered up n receive is quite high through the PA. Once I take out the PA transistors then I

Ups, I should have mentioned: I got the USB failures with a High-Band QMX, not QMX+ But in theory that shouldn't matter... -Tobias

Ah, you beat me to the post there Stan.
