The last time I used a CB (post- conversion of a legal Midland unit to ten metres back in the mid-eighties) was about '89 when some of the lads on attachment to Penrith devised a system we called 'Drink-Link' to see who was going out for a pint that evening. Someone* came up with a basic tone-squelch mod based on an NE567 if I remember correctly. As we were rather scattered it made sense to see who'd be out 'n' about without squandering a telephone call to various landladies, digs, etc... No mobile telephones back then! Not for the likes of us anyway.
My cousin's husband used to laugh when I lodged with them at Blackpool back in the '80s when I was at Bispham Tech. I'd go out in the car for a natter on two metres, but I'd telephone one of the other chaps first to see if he'd be about!
CB was a fun part of the great radio journey for me and I made some lifelong friends through it.
