As I have said before, if I had to give up every other amateur radio magazine, SPRAT would be the one I'd keep.
Back issues are available on a CF stick that represents incredible value.
GQRP membership costs are very modest.
Simple QRP projects, 10m, 8m, 6m, 4m, FT8, 160m, WSPR, LF/MF, sub-9kHz, nanowaves and other random stuff, some not related to amateur radio.

I quite enjoy QRP (low power) and like finding out how far really low power goes.
As an example, today one station was giving my 200mW WSPR beacon a report of -3dB S/N suggesting the even microwatts might have been enough.
I have been a member of the GQRP club for very many years. Their quarterly SPRAT magazine (A5 colour) is usually packed with ideas for simple circuits. As I have said many times, if all other radio magazines had to go, SPRAT would be the one I would keep.
Back issues of SPRAT are available on a flash drive.
The RSGB has a page about QRP. See https://rsgb.org/main/technical/qrp-low-power-operating/
It is entirely done by volunteers without payment. As I have said many times before, if every magazine had to stop this would be the last to go. Perhaps not this one though!

SPRAT is published every quarter as a colour A5 magazine. It is packed full mainly of simple construction projects and annual subs are very low. It is entirely run by volunteers with back issues of SPRAT available on a flash stick at a very reasonable sum. Well worth getting.
It was very pleasing to see my short article about the use of the ISM bands for QRPP beaconing in the latest SPRAT.
In the UK this means 10mW ERP on the HiFer and 8m ISM bands under IR2030 interface regulations. No callsign is mandated and this is licence free. It is a good idea to use a callsign that WSPRnet can cope with if using WSPR. Likewise if using FT8, choose a callsign that PSKreporter can handle.
Certainly on the 8m ISM band 10mW ERP WSPR is enough to reach into much of Europe on Es. The same is probably true of the HiFer band too.
I have said this very many times, but if all other magazines had to close, I hope SPRAT would survive as it is filled with good QRP projects and news.
It is put together by volunteers and comes out every quarter as an A5 colour magazine. It is excellent value. Back issues are available on a flash drive. It is worth it for this alone!
It is my ethos entirely.

I have been a member for a very long time! It is run by volunteers and produces an excellent colour A5 magazine called "SPRAT" every quarter. This is filled with ideas and projects.
Joining GQRP club allows you to buy parts from member's sales, which includes nearly all the past SPRATs on DVD or flash stick. It is worth joining just for this!
Many times in the past I have said that, if I was suddenly poor, SPRAT would be the last magazine to go. I still feel this way.

This comes out every quarter and is now in full colour A5 format. Most of the back issues are available on a DVD and it is worth joining just for these. If you enjoy simple projects you will find lots to inspire you!
Perhaps one of the upcoming rechargeable battery technologies will be based on sodium (i.e. salt). It is my view that we are on the cusp of...
