The QRPer Board

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...

For years now I've done QRO CW operation with some fairly good head phones. I've built out my QRP portable kit, but realized my head phones would weigh as much as the rest of the kit, and be as large again. I did a quick inventory of my earbud collection, and found they are all "cheapies"...

Here is what my lot looks like: Well, you may consider this antenna https://ftp.unpad.ac.id/orari/library/library-sw-hw/amateur-radio/ant/docs/Introducing%20the%20All-Band%20Doublet.htm http://webclass.org/k5ijb/antennas/All-Band-Doublet.htm place 10ft a support pole at the top of roof and setup a ...

I'd love to, but this kind of thing is never going to happen for me. Well, another idea, looking at the image you posted, may be putting up a "skyloop" or "lazy loop" antenna https://www.dj0ip.de/my-favorite-antennas/my-favorite-all-band/ https://www.dj0ip.de/loop-antennas/8-ban...

well, start by building this https://pa0fri.home.xs4all.nl/ATU/FRImatch/FRImatcheng.htm two polyvaricons, a toroid, some wire and an enclosure won't break the bank; add an EFRW (ska "random") by picking a suitable lenght of wire here https://udel.edu/~mm/ham/randomWire/ add a 9:1 and a dec...

Looking for suggestions for a paddle key that can be strapped to my leg for short activations when mobile (parked up). Current use of a handheld paddle is OK, but I would prefer something "fixed" Grateful for any/all suggestions. Richard M0RGM you may consider picking a so called "pi...

Hi, while waiting for a medical check, I spent some time surfing the 'net and stumbled upon this page about Gordon "Dick" Bird (G4ZU) https://www.essexham.co.uk/gordon-dick-bird-g4zu-information and, at the bottom of the page, I saw an antenna design which immediately grabbed my attention,...
