Citizen's Band "10 Codes"

Not quite Hamming It Up

Though I've been a licensed "Ham" Operator for some time, I got my start, like many, playing with CB Radios in the 70s and 80s.

Citizen's Band is still very much a thing, especially Four Wheeling and some prefer hand held CBs to Walkie Talkies (because of range and frequencies), this list remains quite useful.
