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 one of the youngest UK hams to hold an original 'G3' call sign. These pages include information on my lifetime in this 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

Site Summary

I started collecting and restoring vintage ham radio equipment in 2002, when it bacame 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' This collection grew quickly over a few months - and I have been very lucky to pick up some very good examples. A few bits of Heathkit gear have also been through the workshop !

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 and music synthesisers

Find me on Facebook as ' Steve Shorey' or 'G3ZPS', I have 2 separate pages

Also contact me if you would like me to talk at your Amateur Radio Club - my latest presentation is '999 Emergency - Public Safety Communications Past, Present and Future'. This draws from my 35 years of experience in mobile communications. As of May 2017 I have  given this talk at 3 clubs in the Kent area. NEXT 2017 TALKS - ECHELFORD CLUB (EARS) 27th JULY and BRATS RADIO CLUB RAINHAM KENT 28th SEPTEMBER 2017, 8.30M

I am a member of one of the oldest UK Radio Clubs - Cray Valley. This club has a large membership, is very well organised and caters for all aspects of the hobby - including a comprehensive training programme. Email me at

Latest - July 2017


Two very early KW2000s  came along in late May, both from the same job lot  with PSU's and close Serial Nos (299 and 313). These duck egg blue front panel models are from around 1964. Neither had been tested, one had been partly restored and one left for years. After finding numerous faults and botched repairs, both have been electrically and cosmetically restored over 5 weeks..although as any vintage equipment restorer will tell you..another little fault is never far away!
