It was the 2m backpacker contest today. From what I thought was not a very good location where I live, I managed contacts all over with 10 watts and. 7 ele yagi. Well chuffed

When I was first licensed I spent a fair bit of time on 2m SSB and I used an 8 ele beam and 10W.

Some of the inspiration for the Goodier/Warc PSU probably came from the earlier Marchwood PSU design first shown in PW in June 1983.

Some parts of the circuit look to be the same and there's some useful info in the PW pages. I think it appeared in several issues of PW that year.

I'd be interested to see what display you choose for the front panel. There is a pilot hole in the front panel on mine but I never got around to buying a suitable meter.

Annoyingly, I did have a beautiful pair of Sifam meters and a shunt that got thrown out in a clear out years ago, when I decided I was too busy to play radio any more. I've gone down the cheap Chinesium route, will report back on whether they are any good.

I've used those, they are 'OK' as long as you don't mind a little inaccuracy on the readings.

I used similar meters on my valve AM TX and found them adequate but somewhat underdamped.
