Radio Related Ramblings

Hi,  Welcome to my website which I hope you will find useful and entertaining.

I'm an electronics engineer and licenced radio amateur, however I do wash, I am married, and can be sociable when required !

These pages mainly reflect my interests in Radio communication, but a few other subjects and interests are likely to sneak in, probably whilst I'm being distracted.

Background

Even when very young I was interested in all things electrical

                                     

As I got older this interest became more focused

                                                   

In 1974 I obtained my Amateur Radio Licence which I have now held for 30+ years
Some of the highlights include:-

Manchester

First operation was with a Pye Ranger on 2m AM - tuning High to Low for contacts
Pause of five years

2m NBFM using a Trio 2200G portable tranceiver
2m using modified Trio TS700  - mainly FM DX, SSB  and Satellite operation


Home built items included:-

      4CX250B Amplifier
      10 ele IP quad for 2m
      Copy of MM 2m to 70cm Transverter
      23 cm transvertor using nasty high level 23cm mixer (10w of 384MHz  injection)
      Much modified IC22A for 2m and 70cm mobile operation      
      In-car UHF talkthrough and control system using PF1 modules and CMOS logic
      Car to home UHF link, remote control of TS-700, RX AGC varying TX power
      UHF talkthrough systems in and around Manchester
      Other stuff for student events !
