Welcome to my site, it contains mostly technical topics and some rather eclectic subjects such as (historical) British Naval Slang and the words to British National Airs!

Educated in Electronic Engineering, I am a Chartered Engineer and specialise in the design and use of microcontrollers and have a wide ranging knowledge of these and radio communications. For those who know of him or have read his books, I was lucky to be tutored in my subjects by Professor Douglas Lewin !

My personal aim is to transfer as much of my knowledge to others in the most easily understood way I can and particularly avoiding the so-called obfuscation techniques used by many! Most of my current projects use the Arduino, ESP8266 and ESP32 micro-controllers and are documented in these pages for your reference and use. Code for all projects can be found at ‘GitHub G6EJD’.

As a UK Radio Amateur my callsign is ‘G6EJD’, which I’ve held since 1981 and currently operate on the following bands from HF on 80M (80 Metres wavelength or 3.5Mhz), 40M (7.0Mhz), 20M (14Mhz), 17M (18.1MHz), 15M (21MHz), 12M (24.9MHz) and occasionally 10M (28Mhz)  together with VHF on 2M (144Mhz) and UHF (440MHz). I operate (QSO) using most transmission modes of SSB, FM, AM, CW, PSK, QPSK, HELL, FSK, MFSK, SSTV and Olivia, plus a whole lot more… I’m working towards a worldwide award known as eDX100 that requires me to make radio contact with 100 countries and so-far my country count is 85, so just 15 more to go.
