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

Decided that seeing I have the GPS installed, to revisit beacon mode. Setup all the parameters including frequency 14097.200. Well it seems to Beacon OK...I can see that it is transmitting. Problem is

I've wondered if the second stage of the 10W linear could be hooked into the QMX between the existing PA and the LPFs, sort of where T501 is.? T501 would become two transformers, one would provide

See operations manual, pg 65-68 for all the details. Make sure to turn on/power cycle the QMX -after- you plug it into the computer so the serial port will register properly in Win10. If choosing QMX

Thanks, Hans for your reply. I have been 100% CW op for some time. I was looking for a potential Lab599 TX-500 or KX2/KX3 (or fill in the name of another "QRP" rig) killer. I know,... much different

qmx with win10 laptop. 2.7 wsjtx when configuring radio it allows. me to select qrplabs qmx. but does not like and. selection for audio what do i need to do to get digi modes/ft4 working? does anyone

The extra high output at 160m is normal.? Hans previously said he will reduce it because associated with it are high peak voltages at the BS170's exceeding the manufacturer's rating.? You can remove

From your photos, your soldering looks fine. The fried transistor could be causing that continuity now.? Since you have ordered a new one, you could just remove the current one and see if the short

Hi all I have just built and finished my first QMX+ and it worked first time well impressed. Just one question on the power output which I am measuring into a dummy load. On 160m I am getting 7.2w,
