The QRPer Board

not the antenna you're looking at

but it's portable and covers the desired bands, so may be worth a look

I'm in the EFHW or resonant dipole method category for my activation sessions. At 5W every DB counts, so I would rather use a dipole and tuned coax length. Plus, I don't want the extra kit. An extra point of failure, too. But, that's just what I like to do. I say use what ever you like and keep hav...

Nice ! Did you consider giving the PCB a case, even a plastic food case should do and will protect the circuitry

did you consider this filter ? https://www.sotabeams.co.uk/ft-817-filter-module-ssb-cw/ not the same as the collins, sure, but the price seems reasonable and the filter may help improving CW reception... and then maybe you'll find a collins filter in a future further infos https://kd0hbu.com/2022/0...

THIS is the spirit behind this forum, thank you both, guys !

my usual "go to" for propagation infos is "VOAcap for ham" https://www.voacap.com/hf it has a somewhat steep learning curve, but there are a bunch of infos and primers, and the results are worth just in case https://www.voacap.com/itshfbc-help/voacap-faq.html#:~:text=VOACAP%20is%...

2. Do I need a 9:1 unun for a random wire If I'm using a tuner like the ZM-2? well, there are two ways to use a "random" (or an endfed, for that) either bring the wire end directly to the ATU or feed it using a run of coax; the 9:1 is needed only in the second case, in such a case we're t...

There is a trapped, built-in mini tuner design on QRP guys but it looks complicated. I didn't see the schematic for the tuner you're referring to, but the simplest one imHo is here https://pa0fri.home.xs4all.nl/ATU/FRImatch/FRImatcheng.htm if you look at the various builds images you'll see that fo...
