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

 Welcome to G3ZPS Ham Radio.

Autumn 2021. After 18 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.  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 ?'. Over the last few years I have spoken both in person and online to over 40 clubs including the US.  Send me an email if you would like an online or in person talk for your club. My QRZ listing has my talk diary for 2021 and is kept up to date.

Autumn 2021 latest.

National NC101X from a local SK estate - I saved it before it was dumped. Dates from 1937/8, ham bands only and not a clue how it ended up in the UK, I cant remember seeing one in all my years of hamming. One of the 'moving coil pack' receivers and looks like an early HRO - after cleaning it looks pretty good. Decades ago someone did a poor job of recapping the built in PSU so they could add an HT voltage stabiliser valve for the VFO. I changed all the electrolytic caps for modern ones. After a thorough check I ran the heaters up (using a 115v step down from 240v), waited a few hours and then added the HT. Aside from a dirty wirewound RF gain pot it came to life straight away. Works very well indeed and sounds great with 7W of audio through its original speaker. As always, more to do !
