Re: I completed the assembly of the new QMX

the red dots give me a short while the blue dots are ok, I don't know what to do. Giuseppe iu8eun
I tested at this moment with the DVM in the points marked in blue on the photo and it doesn't bring any short circuit.? Should I check somewhere else that there isn't a short before powering the QMX????? Thank you Giuseppe iu8eun
There is no short circuit on these two points.? I already tried it last night. Giuseppe iu8eun
Hello Giuseppe
If you have the?short between the Q103? and Q104 drains you have to resolve this BEFORE applying power.?
FYI I have now added this to the assembly manual, I uploaded the edited version this morning.?

Do you think it would be appropriate to try to make the first start to load the firmware ???? You can look for the problem elsewhere in the tab.? Thank you . Giuseppe iu8eun
Hi Dav, thank you.? Having already assembled 2 QCX MINI and 2 U3S including 1 multiband and 3 QLG I had no difficulty building it, you just need a lot of patience, a steady hand and an eagle eye.? The space is very limited and there is the risk of burning some nearby smds.? I'll see what I can do tonight.? Thanks to Hans who keeps us active with these magical little radio boxes to build with which you can work wonders in long distance qso.? Have a nice day. Giuseppe iu8eun
Hi Giuseppe,
Well done on building the QMX.
You will need to install the firmware before using the radio, in accordance with the instructions in the assembly manual. It's nothing to fear; basically just drag-and-drop the firmware file.
Good luck!

Hope it works the first time you turn it on.? Thank you and good day. Giuseppe iu8eun
