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 'active' 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. After a 40 year gap KW has started up again, although the single web page gives no clue to any future products - click here. 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' 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 older Heathkit and Yaesu 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, music synthesisers, run my own music studio and play the guitar (a lot!)

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 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  October 2017 I have given this talk at 5 clubs in the Kent / London area with 3 booked in 2018 at Canvey (Essex) Crawley (Sussex) and Bedford

Latest - April 2018



 KW77 receivers from 1962 - 1965. Both working well after a few simple faults and key component changes. My friend Mr Ham Radio Bodger has been fiddling in both of them. When the dual concentric RF/AF gain control failed in one he drilled extra holes in the front panel for the RF gain and mains switch - and changed all the knobs. For some reason I will never know he also painted all the white push buttons in garish colours. The Mark 2 model had passive smoked for decades and seen some heavy usage. Although it came to me very dirty and unloved, it was back working after extensive cleaning and 3 days work
