Re: QCX 3D print
Yes I printed 1.
Found a couple of snags but easy to fix with file.
If I recall the cutout for the power connector needed some adjustment and the cutout for the LCD needed enlarging.

QCX CW TRANSCEIVER problem.
QCX CW TRANSCEIVER. When I turn on the transceiver I do not receive anything, but I only listen to a sound like a self-oscillation. I attach the audio file. Some idea ? Thank you.

Re: QCX 3D print
Has anyone tried the short version yet? I prefer to have power source outside the transceiver box.
If not, I will be attempting the short version when my printer arrives. Probably a Christmas break

Re: DVM/RF detector header Question
HI Barry,
That is very low indeed. Please double check the solder joins in the LPF, especially on the toroids, make sure the enamel coating is removed.
Also check for continuity between the PA mosfet

Re: ZL1RS balloon flight - BB01
Bob
I note that you are the only one receiving BB01.
I know that you have extremly sensitive ears.
But is this what you would expect ?

Re: QCX Off Board Mounting wire
Hi Wes,
I used 0.14mm2 which is roughly equal to AWG26. For the supply you might want to use slightly thicker wire, AWG24 will do as it is rated to 2.1 A @ 75degC (typical current draw is 500-600mA

Sorry, did not answer your specific questions...

Hi Roger,
It certainly is addictive, especially if you try to build ‘outside the box’ ideas. I have built a multi band hopping rx and a multi band tx/single band rx transceiver, but your ideas

Having fun with T1 on 40M QCX
After winding T1 for my 40M QCX, I decided to have a little fun before mounting it, and perhaps get it right before mouinting it. I installed some header pins at unused location C8 (in the 40 meter
