Re: rookie mistake
I've got one of the yellow ones too and they work great. Just be patient
and make sure it's up to temp before trying to use it.

Best desoldering tool is the Hakko or similar:
but it's rather expensive. I've found another one that is very inexpensive and works nearly as well as the Hakko. It is a lot slower to use , especially

Re: How hard would it be to rework the QRP-Labs Receiver board into a Quadrature (up converter) transmitter board?
Yes, but not easily as it means breaking multiple paths. and arraging switching between RX and TX.
Non trivial!
No.? The most direct kit (if still availabe) is the SOFTRock Ensamble TRX? as that

Hi Steve, all
Thanks, that was some interesting reading. MicroPython, CircuitPython and

Re: #QMXplus Are others finding the need to remove turns on all LPF above 80m?

I sure hope not.
I've built a QCX+, two QCX minis, three QDXs, two QMXs, and a QMX+.
All toroids were wound using the same counting procedure.
And my toroids look like the ones in Hans' pictures when

Perhaps a silly question, but are you sure you are counting turns correctly on the toroids when you wind them?? Every pass through the toroid counts as a turn.? If you have fallen victim to

Mike,
The Softrock TX is just about minimal. A schematic here https://www.wb5rvz.org/ensemble_rxtx/index?projectId=14

James, I saw this message. Some later discussion made the impression this problem was solved.

Re: rookie mistake
I've made plenty of "rookie mistakes" over the decades (more as a non-rookie than a rookie) and I've used many of the de-soldering techniques posted here.
I'd like to add another tip/technique.
