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 I was hooked. Unfortunately due to various circumstances I never did anything about getting licenced until 2012, a gap of about 43 years.
I run a small business providing I.T support www.itsouth.co.uk to companies in and around Southampton and the New Forest, typically for those who do not have I.T skills in-house.
I also 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!
All HF bands 160m - 10m
Kenwood TS570DG into a homebrew 60 metre horizontal loop antenna fed with ladder line. The loop is bent into 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!

Home Made Active 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 one support for the loop. This pole is fed with a 9:1 Un-Un and is a perfect match on 17m, it also loads nicely with the rig's built in auto-tuner on 20, 15, 12 & 10m. There is also 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!

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!
