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

 Welcome to G3ZPS Ham Radio.

First licensed in 1970 at age 16, I am one of the youngest 'active' UK hams to hold an original 'G3' call sign. In 2023 I have held my callsign for 53 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 - I have 3 prepared talks ; '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 ?'. The third is a potted history of the UK Company KW Electronics. The KW works was near to where I live and I have an extensive collection. Over the last few years I have spoken both in person and online to over 40 clubs including in 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 and is kept up to date.

Spring 2023 latest.

Donated KW202 and a couple of KW tuners. The 202 receiver is in pretty good condition and after the mandatory change of resistors which had more than doubled in value it works quite well. KW put the wider 3kHz mechanical  filter in their 'G Line' receivers - its a bit too wide for SSB on 21st century crowded bands and too narrow for decent AM reception..

There are other compromises in the design as KW grappled with the limitations of the KW2000 series architecture they had stuck with through the 60s. It looks like they could not afford the R&D to innovate and move forward. After being sold to Decca in the early 70s the low profit margin on ham radio equipment (coupled with declining sales) was effectively the death nell for  KW 'G line' SSB equipment.
