Over the years various products have been designed and manufactured for the Amateur Radio market.


Circa 1972 saw the birth of the MK Slowscan Tv Monitor.

A set of 6 PC Boards in a Mother daughter configuration.

These were the days of 8 second SSTV. On FP7 phosphor long decay CRTs.

Most were EX Gov surplus and needed Focus magnets robbed from some old tv set.

The company H.L.Smiths of Edgeware road, agreed to fabricate my aluminum cabinet

and post out to customers with all holes and fixings including mounting brackets for the tube

and the all important front panel cut out.

This combination went all over the world. I think the total cost to get this working was in the region

of £35.00. When Robot stuff was Circa £600.


Circa 1981 saw the BBC Computer hit the streets .

An interface was designed to do AMTOR-PACTOR-RTTY interfaces while

a phone call from G3WHO Peter was working on software for these modes.

We joined forces and had a very successful partnership.


Around this time my son Stephen G8UEE wrote what was the first SSTV software program

for the BBC. I designed an interface and it was a big step forward from CRT type SSTV.


Then the PC hit the world. Is there no rest I thought. So next was a series of interfaces for the PC

for PACTOR-AMTOR-PACKET.


These were produced for some years.


Then Peter G3PLX got his big lump of gray matter working on PSK31.

WOOPS another change on the horizon.

We have a lot to thank Peter G3PLX for.

Off I went again. And as you can see by my web page its still going.

More Soundboard modes more software.

Wonderful free software and great fun.


This year will see me hit 75 years old.

My wife keeps talking about retirement.

I thought I did retire 15 years ago from 35 years in Bio-Medical Electronics with the N.H.S.

But it must have been a dream.


I was licensed in 1956 as an SAC in the RAF National Service.

I went thru RAF Compton Basset to learn my CW. 18wpm

And RAF Whitall to learn my faster and foreign CW. 25 wpm.

What a great opportunity it was to learn what is my favorite mode.

All day to learn it in and paid for doing it. The equivalent of 80np a week.

So 50 years after demob I still have a morse key on my bench.

And there will always be one there.


I must thank my son Stephen who has always advised his old dad on all things in computing.

Its great to have a resident computer wizz in the family. So there you go.

Thats more or less the history at this end.
