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

Re: SSB Mike wiring?
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

Re: Should I just go ahead and order a QMX+?

Should I just go ahead and order a QMX+?
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.

Re: SSB Mike wiring?
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

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

Re: QMX+ high pitch noise on power. Now dead.
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

I measured the frequencies used for phase calibration on my rev 1 QMX 80-20.? For 80, it is 3.560MHz; 60, 5.346MHz; 40, 7.061MHz; 30, 10.123MHz and 20, 14.061MHz. The settings of the band

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

In absolute,? I presume it is set to a level of 50 or higher.? One possibility- I understand that if SWR protect is triggered, the side tone won't be generated.

Re: QMX won’t power up
Can you measure the current draw from your power supply to the QMX in the following three conditions:
1 - while QMX is powered off (remove power cord, then replace it to make sure QMX is off).
2 -

Turning the EQ on and maxing it out to +20 took care of my distortion problem. Also tried the QRP Guys microphone and everything seems to be working. Before that it was unusable.

Re: Figuring out why no keyer sound and updating my QMX Menu Reference to Firmware 1_01_003
My CW practice and normal mode sidetone volume works fine, just like before the update.
Check to see if your sidetone abs/rel or sidetone vol settings somehow got changed.
