Ham Member Lookups: 1702


I started playing with electronics in the late 60's encouraged by my father who was a radio engineer in the RAF during the war working on R1155's & T1154's.

I spent a lot of time dismantling military surplus equipment which was easily obtained in the 60's, and experimented building all sorts of things, including the odd transmitter. Dad bought me a B40 receiver as a birthday present and I started listening to Radio Amateurs, and was hooked!  Unfortunately due to various circumstances I never did anything about getting licenced until 2012, a gap of about 43 years.

I restore vintage valve radios, see www.valveradios.co.uk for details, and below is an example of a restoration I did on an old Sound Sales radio.  I have also designed with microprocessors and other semiconductor devices so I'm not completely stuck in the past!

Operating Conditions:

HF bands 160m - 10m

VHF / UHF 6m, 2m & 70cm

For HF I use a Kenwood TS570DG into a homebrew 60 metre horizontal loop antenna fed with ladder line. The loop is in the form of a rectangle (22m x 8m) and is about 7m high, the long sides run NE/SW. The antenna has gain and some very interesting radiation patterns on the higher bands!

For VHF/UHF I use a Yaesu FT8900 into a Comet GP-3 multiband colliner on the apex of the house.

Home Made Active Rx Loop - Electronics & Control Box


I also have a home made vertical which acts as one of the supports for my wire loop.  There is a scaffold pole driven into the ground with a machined nylon insert that seperates it from  another scaffold pole acting as the vertical antenna.  It is fed with a 9:1 Un-Un and is a perfect match on 17m.  There is an extensive ground radial system for the vertical, and for when the wire loop has the feeders joined together and fed against ground for 160m operation!

Vertical Antenna

9:1 Un-Un in the process of being contructed. 

The box is an IP65 enclosure with all external fittings being stainless steel. The toroid is encapsulated in potting resin before deployment outside.

To this - like the day it came from the factory!
