Re: Is Hans OK?
Hans's business would have been devastated by then, by cheap clones using his stolen IP. We should extend him the courtesy, of setting his own work schedules, and meanwhile enjoy the fine radios he

I would think that Hans and his wife are pretty busy around Christmas time with 2 small kids soaking up the wonderment of the season. Hats off to you and enjoy your family. 73 Kees K5BCQ

Re: QMX+ No transmit or receive
Okay. I will still consider today as a win. However i still have audio and sideband suppression sweep issues and filtering issues. SWR sweeps good though. I still do not hear any stations if i listen

Re: Is Hans OK?
On a recent Ham Radio Workbench episode, this concept was discussed. The idea of making software open-source is an ideal, but impossible to then maintain the cheap knock-offs that get created. After

Re: QMX+ No transmit or receive
Congrats Joel!!! A big step forward. Now you may check the LPF section using the sweeps. If it's ok at least for some bands the RX problem would be located from Q508 up to IC407. 73 Ludwig

Re: Is Hans OK?
It is the holidays, not quite new 'ears. Maybe he is spending time with his family. I doubt that you are going to see him turn over his software development and put it on GitHub. That would be

Everything is very quiet on QMX updates. Just checking whether everything is Ok with Hans. I know he wants to keep the software private to avoid ? Chinese clones, but I can’t help thinking that if

Re: QMX+ No transmit or receive
Okay. I have finally experienced some real progress! I went poking around Q513 and Q515 and noticed that on the bases, i had continuity to ground at a rate of about 30 to 40 ohms. Lol, i don't think

Re: U3S & 10W HF Amp Combo on 160m!
Al, coming back to thoughts of doing a 160m WSPR beacon of my own, wondering if I can learn a bit about the oddities of 160m propagation.... How do you trigger the amp on TX? RF Sensing circuit? Or is

Re: 50W Amp - no output #50w #problem
Clue number 36 in the series. As mentioned before, the QCX-Mini has no issue. Only when I use the QCX+ does this happen. Now, I have discovered completely by accident, that if I place my QRPguys

I have also noticed that DAC also originates from pin 29 of what i believe is IC203. Does this possibly mean that the I.C. may be defective? The pins are SOOOO small and i would rather not probe if i
