The manual, including the pictures of the construction, both show vertical mounting. I see no disagreement with the board. Look closely.

Considering that the 78M05 has a different pinout from the AMS1117, how exactly are you going to hook it up to the Rev 1 board? I'm interested in trying this myself. Is it possible to simply get a Rev

Richard Feynman used to say that it took seven years to teach students how to do quantum mechanics calculations the easy way. Hm.

For the amusement of experienced troubleshooters
I spent 20 minutes trying to hear the output of my 160m rig on 20m. On the bright side, it's a good thing I failed.

QCX-mini update: solving the microphonics problem
Before the change to Siemens as the unit of conductance, we could have said, "There's always room for one Mho." 😎

Advice wanted: QCX-mini capacitor microphonics
Maybe that explains why some of my very old 105 caps are so much larger than the new ones - no SMD inside.

If this is true, it's a source of worry. If it's not true, it's a source of worry. Whether it's true or not, THIS IS NOT THE PLACE TO POST THIS SORT OF THING! Knock it off.

Should the pins JP3, JP4, JP5 be soldered such that the longer pins stick out at the front?
#qcx
One way to avoid this problem is to put the connectors on the pins before soldering. The connectors should lie flat against the PCB. If they don't they are on the wrong end of the pins.
