The question and answer below was posted in another forum. Is the answer
correct? Did the 23 channel radios effectively lose type acceptance circa
1987 and are not supposed to be used on CB after that time?

Question:
I've heard about that from time to time but never understood - why are
23-channel CBs illegal to sell?
Answer:
Because they are no longer type accepted. Anything after 1987 that is a 23
Ch rig is no longer type accepted and can no longer be sold, traded, given
away, or of course used on the air.. But try to tell that to all the guys
that collect the old Trams and Brownings!


40 channels radios became legal on January 1, 1977, 10 years before 1987.


I believe you can no longer sell, trade or give away 23 channel radios,
but you _can_ sell the microphone and leave the radio attached!

They didn't lose their type acceptance. They are grandfathered. All the
other rules apply. If you modify them to get the other 17 (or more)
channels from them you lose your authority to operate it. Same as any
other transmitter adjustment that results in more then 4 watts carrier
or greater then 90/95% modulation.

If the radio you're running is clean and clear and not bothering anybody,
just go ahead and use it. If you start getting complaints, don't ignore them.
Chances are real good, you'll lose.

Happy radioing!
