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

For my test, I was watching the output on an oscilloscope.? It clearly turned off at the end of each test.? ?I didn't even glance at the front panel, so I can't say if the power meter there stuck

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

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. Stan

I changed it to Relative and there was no change

It is set for Absolute

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 -

OK it is WSJT-X 2.7.0 running under Win 11.

stan. tnx so much for the tip. everything is working great. ? i know i had read that but only when first received. the QMX. ?at the time i only wanted to do CW but now i wanna try some of the new

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. I now show power out

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. Stan KC7XE

Hi All, Has anyone tested CESSB vs. SSB. Is the claim and brag ( marketing parlance)? that it is like having a 10 watt output something the 'brave' feel after installing the new firmware? Is there a

I updated my QMX and in the process I get no sound during practice.? It is sending but there is no volume. any ideas as to the issue?? Has to be a new setting. In the process of figuring this out I

You can only do this balancing act with bands which share a lowpass filter.? Otherwise, it is mostly the output transistors (and I suspect their drivers, which have to drive their gate capacitances)

Enzo, I checked a couple of IMD optimizations on my QMX, and this does not happen. Others should check. Anything else special about your setup or the sequence of test steps you did? Stan KC7XE
