stupid but it took me some time to understand. The COM Port can only serve for one program so if you have i.e. a logging software running with the QMX WSJT-X will not connect to the QMX. In my case I

Hi Hans, I have recently ordered a QMX+. Will it come with the CESSB update or will I have to install that myself please? 73 Ken G4APB

CESSB is more than enough. <3 73! de Bekir TA2RX 29 Mar 2025 Cmt 10:12 tarihinde Hans Summers via groups.io <hans.summers= [email protected]> ?unu yazd?:

As a lurker with a QMX+ kit in a sealed box waiting behind a few other projects, "The capacitors are trained to hide in the knobs on these kits" is exactly the sort of nugget I'm looking for! Thanks,

Don is correct I know in the last couple of years I've made an important announcement at Dayton (2023 QMX, 2024 QMX+), please don't get used to it! I don't have capacity to do that every year. 73

Hi Stan Thank you for the quick reply.? I bypassed the LVDO but it made no difference.? But I will try another source.? Thanks...

I would first try a different power source.? Maybe something in your new LVDO is limiting the current such that QMX+ can't complete its startup.

Hi After installing an outboard LVDO voltage regulator (ND6T circuit) my QMX+ boots up to show "Initializing: Audio system" and doesn't respond any further.? Putty doesn't respond either. I have used

Try turning on the EQ then set the EQ to +20. Listen on another receiver for a change. My QMX would start to get raspy at a setting below +14. I set mine at +20 (max) and it sounded pretty good. Then

You can get further on 3W than you might think, I was quite surprised. The PTT signal is already avaliable,? but needs configured.? There is no time line for the Basic code - I think you could

I don’t think I’d hold my breath for Dayton.

Or should I wait to see what's coming out at Dayton that will be even more amazing? But then I won't have time to get it ready for Field Day. Decisions, decisions.

And I just tried my Yaesu YD148 desk mike.? That worked also.? Bet it sounds better than the Baofeng.

Hello! Browsing the QRP-labs website, I was excited to find that Hans has released beta SSB software.? I immediately loaded it into my QMX+.?? After a few false starts, it was making power, using

For my test, I was watching the output on an oscilloscope.? It clearly turned off at the end of each test.? ?I didn't even glance at the front panel, so I can't say if the power meter there stuck

Is it only the sidetone audio that is missing?? Do you still have clear audio on receive?

Next I would measure the voltage at each of the three terminals of IC101, the 3.3V regulator, when you press the power-on button.? ?But don't press the button for more than a second or so, since it

Nothing special Stan. Ran the calibration steps in sequence, one by one, using 'O', '+', 'O', '+', etc. Will run again and measure the power out in the dummy load for each IMD test (so far have only
