Well, I'm 2/3 through the QCX build and decided not to use IC sockets, hope it all works.

I am not going to use sockets either... Just ordered the enclosure mentioned above from Ebay, We'll see...

I got my kit this morning, well, late morning, and it's almost finished... Except that C17 is missing! >:(
Winding the 68 turns (for 80m) then 3x5T for T1 was a pain. It could have been explained a little better. Other than that the manual is great. I hope I can find a 39nF capacitor somewhere.. I am not the only one, another YouTuber had the same problem, same component I think.


Messy... I hope it works...

Gil, that looks great.  I'm jealous!  Can't wait to hear your operating reports.

Finished!

It works without C17... I will test it later, but output is 5+W, everything works, amazing little radio for $49!

Looks great Gil, I finished mine a few minutes ago but haven't done the alignment yet. I does work and I can hear many QSOs going on on 20 meters. That T1 was a bear alright, but I got it wound and installed. Sorry about your missing parts, that's a bummer. Here's mine.

Well done Gil, can't wait to hear your reports on the workings of the radio.  Mine is serial number 1668 and should be sent mid November. Excited

Good work Joel, your T1 looks much better than mine but no way 68 turns was going to look good.

Now I need to put up that 8010P end-fed on the roof...

Which band Steve?

I finished the alignment this morning and I was impressed at how simple it was. I have been copying quite a bit of activity on the 20 meter band. The power output seems a tad low though, 1.6 watts at 13.8 V and 1.4 watts at 12.8 V. Maybe that is all to be expected at 14Mhz. Anyway 1.5 watts is plenty to communicate with.

Just updated the 1.00b firmware to 1.00c using a Arduino ICSP made out of one of my many Arduino UNO clones. Worked great. I'm having a blast with this radio. Got to figure out how to install in a enclosure next.

I just ordered an AVR programmer, super cheap on Ebay:

Unfortunately, the missing C17 has to be 39nF, so Hans is sending me one..  :(

This postpones my video unfortunately, but then I will be able to add a bit on upgrading the firmware.

Hello Gil
Mine will be for 80 metrs

Need to work out a decent antenna for 80 , while I wait for the radio,
Did have a dipole, but that was not very successful.
So will try with an end fed, and use my ZM 2 atu to begin with

A W3EDP would work great with the ZM-2...
