I was involved in CB radio repair in the UK back in the eighties. I wrote "The Midnight Express" newsletters, various articles for the UK CB Radio magazine, and "The CB Eprom Data Book" which was ostensibly telling you how to convert a rig to 10 metres but, if you had half a brain you could use the methods to add lower bands instead!
I'm also a lifelong friend of USA CB Guru Lou Franklin, who has published many books and still sells books and mod kits from his base in Tucson, Az.
