10-4 Good Buddy - one example of many: Voice Lock was known in CB land as a "slider"; on an amateur rig it is known as "RIT". On some CB's it also worked while transmitting (XIT).
I used 148GTLs and my still owned base 142 GTL since those times. All kinds of SSB traffic on 36-45... Still today I can tell 10 meters opens when I hear folks on 38 LSB 27.385 ... then I can call CQ on 10 and someone might come back to me while the CBers are running a pile up over pile up as they do....
I could be dead wrong because as old as I am I was pretty young when 11 meter CB first started. I was already a licensed ham radio operator (Novice class) so I didn't pay much attention to CB. A neighbor was heavy into CB though and as I recall originally it was AM only with channels crystalized and selected by a rotary switch. As I said I might be mistaken. I think SSB followed a short time later and at the same time the # of "channels" was expanded as well.
^I think you're 100% right. I was never on CB, but did install many CB antennas for people back in the mid-to-late 60s, when it was really thriving and seemed every second car or truck on the road had a CB whip antenna. In '66-67 or so, the rigs mostly used tubes and were crystal controlled, but some were really high quality (like the Johnson Messengers and similar). No "frills," but they were reliable and worked well. Although it may have been legal per Part 95, I never saw an SSB CB rig back then.
