About 6 of us in the local club are building the 20M
version as a club project.
Mine are for 80M and 40M, so I won't have a QCX there,
but I could dial my "big rig" down to 5W. We might be
a bit close for 20M though. Of course, that's assuming
you can send slow enough for me!
Just a suggestion... I found it tricky soldering the
single pin headers in place. If I was doing it again,
I would probably install them right at the beginning
when they weren't surrounded by other parts. Sticking
the pin in some dense foam might be a way of holding
it upright while putting the PCB down over the pin to
solder it.
I put the male pin header on the LCD display instead
of the female connector (a la BITX) so I soldered the
female connector on the QCX board. The stand-offs are
a bit long. You would think I would have learned from
the first one, but if there's a third, I'll sand about
1 mm off the stand-offs before adding the LCD display.
That way, the header can just be pushed flush down
onto the LCD display for soldering. With the stand-offs
a bit long, I ended up pushing the pins a bit further
through the plastic part of the header, so the short
pins made it only just to the top of the LCD circuit.
I used the LCD circuit board to push the male pins
down into the connector and then soldered them.
Good luck with the club project!
