{"replyToPid":0,"replyTo":"","text":"The origin of 10-code and repeating the code actually stemmed from the first tube c.b.s (c.b. meaning citizen band, which was the designated band width frequency used for c.b. radios)...it took awhile for them to warm up and the transmissions weren't always very clear...so 10-1 through 99s were used to convey simple, clear messages (like the good ol 10-4 meaning \"understood\" or \"copied\") I don't remember the sheriff's name that started it all. But it is some interesting history lol\nI probably have some of that wrong, I have crs today...one of the perks of getting this old!"} |
