QMX NOT POWERING UP

Built the QMX as soon as I got it home from Dayton. Built both the QCX-mini and QDX digital previously without any problems. The QMX will not power up. Tried troubleshooting it with my limited skills

QDX kit ship times
5 messages
I was wondering if the QDX kit ships sooner than the pre-built ones? It is hard to discern based on the wait list as it does not show what is a kit, and what is a built version. Thoughts?

QMX Build Hints
I have finished my build, although I have not fired it up yet. A few comments: 1. This is by far the tightest build I've ever done. The toroids are really squeezed in there. However all of them did fi

QMX manual Mods
3 messages
When published I had a color manual prepared for the new qmx. I am seeing posts of errata to the original manual. Is there a source for these changes so I can change the original manual?

QMX - strokes of genius?
6 messages
#qmx
The QMX was so unexpected - at least by me. And it has, I think, some strokes of genius in its design. Firstly, Hans made it difficult for himself: the decision to fit it all inside a QCX mini case. F

QMX 12 Volts

Sorry but I want to ask the dumb question - is 12 volts the actual ceiling for QMX power supply or is it rather the old "12 volts but it's really 13.8 - 14.0 volts" thing? It's easy enough to reduce m

Hi, finally got a chance to test my HighBand QDX on TX today and started very positive, 20m worked perfectly, have built it for 12v but started carefully with 9 volts so as not to destroy anything :-)

Any idea why I get a key down sound with the dummy load but not when connected to an antenna? I then just get a buzzing sound.
