Shortwave listening and everything radio including reviews, broadcasting, ham radio, field operation, DXing, maker kits, travel, emergency gear, events, and more
A few weeks ago, he received a Grundig G3 from Charles (KC8VWM)–it was in need of repair. Wlod immediately cracked the case open and started diagnosing the problem!
Re: US7IGN radio repair – switching type power supplies generate noise , if possible switch to a battery supply of equal power output . Listen to output, should be less noise . Many of the SW receiver kits from China that I build come with a green toroid wound with wire for the positive and negative rails . My guess is power from the mains is mixed, that is – wind power, solar power, npp, fossil fuel, etc . Solar power use inverters to generate AC from DC . Inverters generate electrical noise .
Working on your G-3 is a worthwhile task.I still have one in great shape,in and out.Going back 8-9 years ago it was my main travel radio and I enjoyed its quality and features.As you said the “Sync” was tempermental,especially with weak stations but other than that a real good performer.I still use it as my wake-up radio.I used longer dipoles 60′ and it did not overload as far as I could tell.From Pa. in the States I could hear Australia & New Zealand with clear audio.I once heard a live horse race from “Down Under” territory.Good Luck with your G-3 and enjoy it’s a keeper
The G3 sync circuit will likely continue to drift over time, or at least mine does. I gave up trying to keep the sync tuning set, as “ECSS” via SSB works if truly needed, so largely a “whatever” IMO.
Agreed. I have enjoyed SWL and AMDXING since I was sixteen years of age due to a Christmas present back in the 1960. At the age of seventy, still a nightly endeavor .
While this gentleman is restoring radios against substantial odds so Ukrainians can hear news and events from the rest of the world, the BBC and other world news organizations continue to demolish their remaining presence on shortwave.
Our friend, Wlodek (US7IGN), who was recently featured in a BBC Radio 4 documentary, has been repairing radios throughout the Russian invasion of Ukraine.

Sigh.
