QCX mini 40M T1 winding #qcxmini #t1 #40m
Hi all, I am just about to commence my very first QCX mini build and I just want to get the community's thoughts on what I am considering in doing for winding T1 for the 40 metre band. I am a little

Re: #qmx video: 52 tips for building your QMX successfully #qmx
Any video on QMX is a good video! Thank you Hans, that you do this work. ( But you still have to work on your acting skills). I had already written elsewhere. EVERYONE who proceeds normally

Re: #qmx video: 52 tips for building your QMX successfully #qmx
This was a challenging kit due to the density on the PCB, but the instructions were very thorough and I was able to complete it successfully. I've made a dozen or so QSOs with it and the performance

Re: Dire need of a part
Dear Karl, I went to the QDX v5 manual and the size of most of the parts in the QDX are 603.?? There is no size given for the 47uh inductors.? All it gives is the inductance value and SMD. so, I

Towards the audio connectors, I meant. Please make sure you've disconnected the radio from power when checking the resistances. Jonathan KN6LFB

Re: QMX won't power off and odd voltages on Q103
I suspect a partial/resistive short from one of the power rails to ground. 1. Can you provide photos of the bottom of the main board and the bottom of the power supply boards? 2. If you remove power,

Re: Dire need of a part
Dear Karl, I think all the SMD parts in the QDX are 605 size or something like that.? It is real tiny.? My cheapie caliper said the length of it was 1/16th of an inch. Here is a picture of a group

Thanks Ron, Will give that a try.? I'm gonna be back in SFO in 2 weeks and will give a try again then.

No wonder Hans cannot keep up with the production demand ... with every soldier and sailor having a QMX in their pocket, they will be like HF pocket phones. LOL

Re: #qmx QMX and waste heat from the finals #qmx
It is doubtful the board is getting hot.? Easy to put a probe onto a convenient location.? Many DVMs come with temperature probes.? (I would consider less than 40C as warm)

Re: Tx and vfo knob off #qcxmini #20m
Mike. Probably all you need to do is calibrate the reference oscillator frequency. The 27 MHz crystal reference is defaulted to 27,004,000 and needs to be adjusted. This is menu item 8.5. If that
