Thanks for all you do. I am excited to see what the future holds for QMX+ Mike Krieger [email protected]> wrote:

Hi all I hereby officially retire the QSX project http://qrp-labs.com/qsx which was started in 2018 and aimed to provide a low cost, high performance multi-band multi-mode QRP transceiver. QSX was an

Well done Hans! Not an SSB op here, but I am very happy to see the Beta SSB firmware finally out, as I know how much effort you have put into it. I am sure you will get plenty of good feedback from

Wow, Congrats! Thank you Hans. Too bad the weekend is a little far, I'll have to wait to play with it ;-) Ciao /Claudio, IU2TUL

Congrats! Great accomplishment :-)

Congrats Hans!

Awesome news Hans, thanks for all the hard work! ?Can’t wait to try it out.

Hi all Attempting to be the first post on my own thread.... with great excitement I managed to send three Winlink emails using my Pi400 computer and QMX+ in USB mode. I installed the new beta on my

Hi all Beta firmware 1_01_000 is now available for the brave to try: https://qrp-labs.com/qmxp/ssbbeta.html That page has a long description of all the new features and changes. Let's keep feedback

Nate, I have read about separating the L14 power source from the rest of the circuits and adjusting it to get the desired power output.? This should be easy enough: lift the power supply end of L14,

When using my QMX+ and T1 Tuner, I insert a 6db 10W attenuator inline between the QMX and T1 before tuning at full power. The T1 is quite sensitive, so no effect on tuning and the QMX sees a return

Any mention of what power source was being used ?

I found that my QMX+ is very noisy on switch on from cold, depending on the temperature in the shack the noise abates quite quickly. Shack temp below 7c it can take longer to settle down. If the shack

I just received my factory build QMX+ and it does have the same tone as the QMX + I had built.? So can it be something within the QMX concept ? I noticed that the volume of the tone is not always

Mine does the same thing. ?It doesn’t like auto-tunes.

Congratulations Hans, Great news!? I am mostly a cw guy myself but I am using my QMX as primary rig for SOTA and then the SSB feature may come in handy for pleasing the SSB crowds a bit :-) I have

That depends totally on the speaker.?? If it is higher impedance (200 ohms or more) it will likely work fine.? If it is closer to 8 ohms, you will need an audio amp. I am planning on testing my old

I'm thinking of a trrs adapter for my hand mic that contains speaker as well. It would require two jack plugs into the qmx, one into ptt/mic and one into phones socket. Question would be if the

There's a PFET at Q7 for reverse polarity protection, it probably won't be on with Vin below 7v. WIth Q7 off there should still be current flowing through the intrinsic diode, but that incurrs a
