Great write up Nick. Hans is a master with the designs of his kits. I truly enjoy building his kits! 73 Kurt - W2MW Sent from my iPhone 11 Pro

I received a version 1 low band QMX in July 2023 so 9 months ago now. I finally got round to building it and I'm going to write up my experience here. Firstly the manual and instructions were

Mike, About all I know is here. https://sites.google.com/site/g4zfqradio/incircuitprogramatmel168#h.tpm1l60t46z I note I have written "[NOTE the QLG2 is fixed at 9600 and my tests so far have

I've locked up my QLDG2 and would like to restart it from scratch. While trying to change the Baud Rate using a wrong program, it now doesn't send text. If I command it to $$VER it gives 1_00b.QG2, so

I used digi to find and hear stuff.? When I get it tuned in and switch to CW, I move up the frequency +0.70.?? Example, if I zero beat on digi at 14.044.30, when I switch to cw, I move up to

I’m thinking the same. 73, Ken

In my newly built 40m version, I have sound, but the gain control pot has zero impact.? The radio just produces a steady volume level. For now, I set C1 to produce a level that an external speaker

Sorry for the double post, but I did discover that using Vox with Bob Cameron's settings for rise and fall I am up and running with Contestia!

This matches my experience too - I had been trying Contestia 4-250 and it was cutting out on transmit and whenever I restarted. I just tried Thor, DominoEX, and MFSK and those are all working. I can

Hi Adrian? you can test the U4B on usb power but it is much better to use a battery and then you will get the correct telemetry voltage and have the gps free of possible computer or power supply

OK Dave, it sounds like there is no connection between R39 and R40 and there should be. One side of R39 connects to ground (0 v) and the other side is supposed to connect to R40. Where they connect

Ludwig, The sweep signal passes through both an LPF and a BPF on its journey from the clock generator to the detector. As the 20m and 17m LPFs are different one should expect to see some differences

I can confirm Daniel's experience here.? I have a new ultra picokeyer.? As built, it would put my QCX and QMX rigs into key down.? I cut the trace going from PIN 5 to the ring, and now the

Ron: ?I got 11.16v off of R40 and 0 volts from R39 and I’m getting 11.6v on pin 5 of IC-10 I’m not sure what you meant by the junction of R40 and R39. I took voltage readings from the wire off

I realize the documentaion says that the QRP Labs QLG2 comes set to 9600 Baud, BUT, is there a way to reset it to 4800 Baud permanently? I still have several devices that are standard of a "few" years

Dunno, Dan. There are a lot of QMX out there now and this specific failure remains at quite a low level. Yes, that's no comfort to you as you had one of those failures ;-( It is also a little

OK Dave, looks like there's something wrong in the area of R39 and R40. Those two resistors form a voltage divider from the 12v input and should show about 6 volts at the junction of the two. That
