Stan *THIS* *5.5 x 2.5mm* plug on https://www.aliexpress.com/item/1005006380829800.html works with *no problem!* other people are using it with their PDs and QMXs on POTA activities. I tried to get an

All the mics I have assembled and tested with my QMX+ (which is now a LOT of mics) have had various results. I have not changed the default settings from the SSB firmware, but some elements pick me up

Thanks Dave.....:)

Thanks Ronald....they look promising...:)

Hi all, This is my experience with the SSB beta release. After much fear and consternation, I took the plunge today and installed the SSB beta firmware in a QMX Rev 1. I attempted to do a

So far everything seems to be functioning well. I have noticed that when using the swr tune function that on some bands the swr reading does not change while tuning an antenna and I have to turn it

Thanks Stan. I think I will also order the same mic Hans used. Comparing the sensitivity specs between that mic and mine shows quite a difference in sensitivity. I am also going to try a higher

That's the same for me, everything is fine in CW and Digi but SSB is weird [email protected]> wrote:

I have the same problem on my qmx. It only happens in SSB mode. In CW everything is normal.

I've broken one of the T37-10 (Black) L512 toroids.? Do you know where I might get a replacement? Thanks, Bill

I finished building my QMX+ today and on inspection I see I've broken the core of L102, one of the switching power supply inductors. It looks like both leads of the winding are still connected to the

In diagnostic on pc it shows 0 watts srw 1.2 on my 40 m dipole

Karl, these results are a bit confusing to me. If I understand, you are putting in a 14MHz sine wave signal at about 15mV, and are tuned to 14MHz. With that setting, you should see the 14MHz signal at

Interesting. Mine doesn't do that (tested in SSB mode on both a QMX and a QMX+ into a dummy load). Sometimes at the instant of pushing the PTT key, the SWR indicator does jump up, but then goes back

Everything seems good when tx 0 watts jumper in were do I start to trouble shoot?

The operations manual states the following, which looks much like your display (with the exception of the CW): During the actual WSPR message transmission, the display shows something like

No, you don't need to do the calibration process.? In that case the phase and amplitude corrections are simply not performed, and you will still get reasonably good results. If you do the

I think you are correct, based on the evidence stated.? Did you perhaps leave your QMX in tx mode when you turned away??? Extended tx time could have burned one or more finals at full
