Troubleshooting
My experience as a Radio Frequency engineer means I can help you with any RF designs you are having problems with.
I'm passionate about radio technology.
My name is Keith Alexander and I have been an electronic design engineer for more than 40 years.
I built my first crystal radio from a kit when I was seven and my first short wave radio at eleven.
More than fifty years later I love helping high tech small businesses and start-ups who need the expertise I can offer but don’t want to employ a full-time member of staff.
