My Personal Interests


Some examples of my home constructed equipment:

A re-engineered SB-310 covering all HF bands

A multi-voltage power supply

An SB-101 that has 160m

Dual Z-Match 1.8 - 146MHz

Station Console

It all started with a crystal set when I was 12 years old and subsequent reading of many electronics books.

Following completion of my engineering qualifications in 1962/3 I have been a design engineer for most of my working life and a Chartered Engineer since the early 1970s. I started working with RF communications equipment covering LF to 500MHz in 1962 including a stint developing high reliability equipment for the Merchant Marine market and switched over to software and database engineering in the mid 1980s. Now retired, I have returned to designing, constructing and operating RF communications equipment in my amateur radio station. I am married with grown up twin sons. My current activities include:

A stabilised version of an HP-23 for use with an HW/SB-101

A stabilised 13.5V 25A PSU

Aerial switch Box

A stabilised power supply for use with 1.4v filament valves
