Something is pulling down on the 3.3V supply so the power-up sequence cannot complete.? That is why IC101 is getting hot - its output is shorted (or nearly shorted) to ground by something.? Or maybe

Jerry As the kits have never been designed/tested? for anything but the standard Si /MS 5351's they were sold with - and the earlier models were pretty tight for code space to cover other options) -

I have just built a QMX, but it doesn't power on and appear as a USB device. I have built it for 9V, and have applied a voltage of 8V from a current limited supply. Prior to depressing the left

Found no issues with the terminal and just debugged a QMX+ Beyond 15 meter I'm losing power, at 6 meter it is less than 1 watt, so I will check the filters again. 73 PA1EJO Ernst

Adding to this, I found this message /g/QRPLabs/message/93093 And started measuring the voltage on the diodes in different bands. When I'm on 20M, D1/D2/D4/D5 are "high" (8.06V to

Many thanks Alan!! After all those toroids I REALLY needed more practice with 44 turns of #28 wire on a T50-2 core! Hi!! -- 73, Rick VE7TK Website: https://www.ve7tk.ca/ ( https://www.ve7tk.ca )

No problem! This is waiting for a firmware update. 73 Alan G4ZFQ

Salut Nicholas Merci pout ton cover pour le QMX. J'ai essayé d'allonger le couvercle avec des languettes de verrouillage aux extrémités, car le QMX glisse facilement lorsqu'il est utilisé comme

I have just finished building a Rev 2 QMX+. It was a fun build and all went smoothly ... with a couple of minor exceptions. 1) For some reason, PuTTY refused to work on my Win10 desktop (it had

FANTASTIC! It worked as advertised. Many THANKS! Sam,AC4OW

I should add that I built this for 9V per the rev 3 assembly manual (not the transformer manual).

I activated #pota us-10658 with the #QMX mid-band I built this morning (5 watts). It was pretty windy so I didn't record any video since I forgot my wind sock. I started with 30 meters and moved

Hello, Was hoping I could get some help on how to troubleshoot my QDX.? I looked through the list, but was having trouble finding quite the right thing. It is a QDX rev 3.? I updated it to the

Can do it remotely using the terminal mode.? I just tried the following steps - may not need all of the steps: * Exit WSJT-X * Enter terminal mode * Select: Hardware-test/SWR-Sweep ( Should be crazy

That was on Ten meters FT8. Ten is wide-open today ! 72, Bill, N4QA/QRP

Yeah, some lessons come the hard way. Like I said in my original post, I know better, frankly, but there you go! Just had another really fun POTA activation yesterday with it, and am looking forward

Great suggestion!? The "S" is a showstopper for remote operation.? Perhaps there will be a way to do it once Hans release his BASIC programmer interface. 73, Mike KK7ER

Sam Be extremely careful using the auto tuner.? When it is seeking a match SWR can transiently exceed 10:1.? This causes high voltage at the BS170 PA transistors that does substantially exceed the
