All sorts of interesting stuff about Ham Radio and old gear from Steve G3ZPS, near London in the UK

 Welcome to G3ZPS Ham Radio.

July 2021. After 17 months of covid a few of us are still running an 80m vintage radio SSB net on some weekdays at 11.00 UK clock time on 3.777 +/-. That means well over 200 weekday nets. Never thought it would last this long...and its not over yet!

First licensed in 1970 at age 16, I am one of the youngest 'active' UK hams to hold an original 'G3' call sign. In 2021 I have held my callsign for 51 years. These pages include information on my lifetime in the hobby and my retirement passion for restoring valve ham radio equipment (or tubes if you prefer). I have built up a collection of Drake (USA) and the lesser known (outside of the UK) KW Electronics equipment.. My KW pages open out to cover my extensive collection, click on the 'WELCOME'  page to get back here. As of September 2020, I can muster around 40 HF stations. I'm always willing to help anyone working on old gear..I never know when I might need their help !

Site Summary

I started collecting and restoring vintage ham radio equipment in 2002, when it became obvious that the equipment may become scarce in the future. My tube equipment collection started with a Drake R4B quickly followed by a Drake T4XB. The Drake collection slowly grew as my enthusiasm to buy waxed and waned. My next target was a UK company close to my heart 'KW Electronics' - and I have been very lucky to pick up some very good examples. Heathkit, Swan and Yaesu gear has also been through the workshop . I am a qualified electronics / communications engineer (Fellow of the IET) and just love taking stuff apart !. Click on 'Lighthouse Larry' for loads more valve / tube stuff .

Look through these pages to see more of the collection and some of the trials and tribulations of keeping this old kit on the air in the 21st century.  I also build QRP tube and solid state radios, audio amplifiers, music synthesisers, run my own music studio and play the guitar (a lot!)'. This is a scientific hobby; build something, modify something, restore something..above all else experiment and learn something.

Find me on Facebook as ' Steve Shorey' or 'G3ZPS', I have 2 separate pages . Pictures of some of my 160m ham radio chums from the 70's here

Also contact me if you would like me to talk at your Amateur Radio Club - my  '999 Emergency - Public Safety Communications Past, Present and Future' talk draws from my 35 years of experience as a professional engineer in the communications business and has been constantly updated.  Over 4 years I have given this talk at more than 30 clubs. The second is a presentation on why some of us restore and use older Ham Radio gear, titled 'Old Ham Radio Kit - Why do we bother ?'. Send me an email if you would like an online talk for your club. My QRZ listing has my talk diary for 2021 and is kept up to date.

Latest Rig Repair

Kenwood TS770E - Early 80s V/U radio that came to me through a friend who had acquired it at no cost..He grew tired of a hard to find PLL fault and was never going to hang on to it. On a whim he passed it on to me as I was getting bored stuck insde through the COVID pandemic. He warned of some serious bodges inside the radio - he was right - it had been subjected to mods and repairs that had me gasping !. After removing quite a few mods I settled down to find the PLL fault. It took quite a few days of head scratching as it could take 2 hours for the fault to appear and sometimes just disappear. Industrial freezer spray was my saviour in the end and it only took a tweak on one trimmer capacitor to restore trouble free operation..phew!

Also new in August 2020 was an ALDA 103, brilliant little SSB transceiver from the USA and rare in the UK. I also built a QCX QRP CW radio from QRP LABS - amazing performance on 40m.
