Ah! ?That would explain it. ?I definitely ordered the QLG3 option. I figured I might as well have the option just in case. :) Thank you for the response! ?I’m very excited to get started on this

There is an SWR tune function in the menu. When tuning from there, by default the output power is reduced to 25% (50% of the output voltage). The percentage is also configurable in the protection

I have used the ProgRock2 in numerous projects (mostly Heathkits), and detailed how to use the device in a recent article for ER Magazine.? Some pointers that may be helpful: - The device isn't

FYI: The T1 autotuner when seeking a match results in very high SWR which may result in transients exceeding the breakdown voltage of the BS170.? This may happen faster than the QMX can protect

I got my QMX+ from Hans at Friedrichshafen , and have enjoyed the build. All was going well, with 4+w out. Then when I tried it with my Elecraft T1 auto tuner, it wouldn't tune. I suspect that the

To add a bit of perspective, you can get a pre-built QMX+ faster than you can get a KX2 or KX3. -- John AE5X https://ae5x.blogspot.com

In addition, the 5V board has a larger 5 watt rated zener diode D108. This is on plug-in PC board number 1 (Vcc) -Steve K1RF

Joan, I use a similar setup, though with an iPhone 15 which has a USB-C port. I tested several feedlines yesterday in the park and one thing happened consistently: with a shorter feedline that

There are a few changes for the latest SMPS boards that I have noticed. On original boards, the tantalum caps have a 'J' marking which apparently means 6.3V rating. The newer ones have an 'A' marking

Alex, Very nice job! -- 73, Dan? NM3A

Yes, you're measuring it correctly from the sounds of it. What's wrong? The receive BPF on the QDX HB is shared between 20m and 17m, so compromises had to be made. On this model, the BPF sometimes

How can one tell if they have the newest version of the PS boards? Bob KG5GTE

If you want it quick, building it yourself is a good option. That's what I did. I received my kit only a few days after ordering it. It took about 8 hours total to build my QMX (plus a little extra to

Dear all, I got iFTx a while ago and I managed to close a number of QSOs with my iPhone 13. This app is not great, it has some limitations, but it works. Last Saturday I tried to activate a summit
