An observation If you have CW practice on and use "tune" it will show a SWR of about 1.7 no matter if a dummy load is connected or nothing is connected. A power meter shows that there is no RF out. It

Hi Mario You might try switching OFF the 80/20m BPF swap in the advanced configuration to see if that makes any difference. That was intended to fix the TX/RX switch instability in QMX PCB Rev 2,

Hi all, Just to say the SSB firmware is working great and getting better with each iteration - this is fantastic work Hans! But I hope you are going to take a break soon, you deserve it :) One

Dear All, This is the mod that I did on a cheap Baofeng or similar microphone from Temu. Really easy and takes around a hour to complete. Works perfectly for the limited testing that I have done.? I

I'm still seeing some strangeness in the 80M sweep: Not enough signal at the test frequency? I'm enclosing it and the BPF filter sweep for reference:

Thanks Peter, all noted > 1. Practice mode does not make sense in SSB I guess. When enabled in CW I agree but I think this his already the case isn't it? Doesn't SSB ignore practice mode? 2.

Hans, few observations/suggestions: 1. Practice mode does not make sense in SSB I guess. When enabled in CW Keyer menu and SSB mode is selected it could be temporarily disabled and then when CW is

I had this too, I just had to press the PTT and that's what I saw on the Monitor rig. Turned out to be too much Mic Gain. My setting is now 43. GL G4GIR

I can confirm this behavior for several Qxx devices. Hajo

Is there any reason the phase calibration only goes upt to 1200 on 80m, 30m, and 20m? 73 Simon VK3ELH

Hans said it is set up for noise cancelling currently. ? You won’t sound very good ..

Hi Roger > Last night I downloaded the latest firmware and threw together a rather Very nice! You might consider posting about your experiences on the SOTA forum. Spreading the word is always

The former output powers were taken using JS8Call software and show the power transmitted with JS8 mode. I took the same measures using the "transmitter test" of Putty, clicking on "T" and read the

I've just tried transmitting SSB using the internal mic to a dummy load, with my K2 next to it to receive the SSB signal and record the audio. Although the background noise was loud whenever I pushed

1. Low Pass Filters I just replaced the 4 BS170 of the PA of my Hi Band QDX and I replaced the "conventional wound transformer for 12V" by a "WTST for 9V wounding", expecting an increase of output

Dan, you are not the first who has slipped with a probe.? Many of us have done that. Yes, it's probably just the smps - at least we can hope so.? It's easy to short the 12V to the 5V or 3V rail,

No small feat, and 3 firmware revisions already released in the first week!

Hi I built a QMX mid-band, it started up first time and everything seemed pretty normal except for low power output. tx into a dummy load with a 11.9v supply: 60m 9.5v(red) 1.7w 1.04swr 40m 9.5v ?

Hi All, So, I see the SSB desired upgrade is now released as a beta version. I decided to glance at Hans, write-up. Hans write I will shortly give a brief introduction to SSB on the QMS..."... And he

I've just been printing them one at a time. It takes 45 minutes to print a set, whether you print an array or one at a time, and this way is less prone to errors in my experience. I did set up an
