I ordered a QMX V2 kit in late January knowing it was delayed until early Feb, but when I was on the website checking my order, I see there is now a V3 of the QMX. Anyone know what the V3 changes

Thank's, 12v,power supply 13.8v, 1 ampere in tx, I read power with terminal prog of qmx and meter of display on qmx, John.

Insufficient data. Voltage built for (9 or 12)?? Actual voltage used for measurements?? Current consumption?? How did you measure/calculate power? 73, Don N2VGU

I received them from QRP LAB. I had to bore out the housing hole with a needle file. -- 73, Oleh, UY2ZA

Bryan:? Use 10X probe setting whenever possible, most probes have lousy frequency response in the 1X position.? Compensate your probes to their 'scope channel prior to use. 73, Don N2VGU

Thanks Guiseppe, I have been exploring www.tek.com/en/support/learning-center ( http://www.tek.com/en/support/learning-center ) Its pretty informative. I still have not learned what the bnc-cable with

Hi, i assembled qmx high band v2, year 2023, but i have low power RF filters sweep and power 20mt :-14 power 2.5w 17mt:-4 1w 15mt:-10. 0.6w 12mt:-9.5.

HI Bryan, Tekscopes and Tekscopes2, look on groups.io Also EEvblog forums. There are certainly others but these have more than enough info. Giuseppe Marullo IW2JWW-JN45RQ

I finally replaced my oscope which I foolishly sold years ago. but struggle to remember how to use it. does anyone know agood online resource to study up on using one?? im not taking about how to

I don't think Hans will commit to the month or even quarter. I am going on the basis that Q4 2024 is the earliest when such option might be available. Considering this, I am currently slowly building

Hi, what you can always do is to add a 5W 3dB attenuator to the PA input to lower the worst VSWR to 2:1. Or you can change the internal 3dB to a 6dB attenuator. In both cases you will need a double

That said, after fixing my ground issue with the QDX - see my other newer message on this issue - I'm now operating FT8 from my Fire Tablet with FT8CN. Yay!

Hi, I am about to order a QMX Kit but I would love a Mid-Band (40-10 or 40-15m) version. I know that are some of you, who modified a QMX for mid-band usage but I will wait for an "official" mid-band

Hello Peter, welcome and thanks for joining us. It was one of the busiest WARC Parties for long. I had 6 QCX/QMX and I think there were even more. Also tha band was quite open. I later worked VK2 on

What did I do wrong? I built my 50W PA for 20M - This is my third QRPLabs kit, having successfully built two QMX first time 'round (high and low band versions) so I get the idea of how the manuals

The power connector comes in different lengths. The one available from QRP Labs is correct, but I also had some I bought from another supplier. I made up a longer cable using one of these without

Jim, IQ mode transforms the QMX into an experimental SDR receive front end so a 48KHz receive bandwidth may be shown and tuned using CAT. Any mode may be received within the 48KHz bandwidth. It is a

Hans-san;? thank you for the nice radio. I want to disable 5M-band on my QMX in accordance with the Japanese regulation, however, it is still activated even though I enabled Japanese Limit on the

It does not seem ridiculously short to me but I would still try to play with lengths and counterpoises. Yannig F4IUJ
