True! CB should have always been on VHF FM from day one.
The same 4 watt carrier as it is now is my guess. There has been NO mention of any other power level changes only mode.
I guess we have to expect them to continue the farce.
It seems most are...
Some are 4 watts AM/ 4 Watts FM and have a high power mode 8Watts AM/8 Watts FM.. (Anytone Smart CB for example)..
But in the Couple Anytone Smarts I've tested, it doesn't have enough Audio Drive (in a stock configuration) to fully modulate the 8 Watt AM carrier..
But that Anytone Smart CB is not a legal CB radio. No different than any of the exports that run much higher power.
And are required by law to have a switchable 10dB attenuator to reduce output to 0.4 watts for use when that is all that is required to maintain contact. Probably the least used of any function.
I've been running export radios in my mobiles for like forever. I seldom used the FM mode, and never used CW. But when I was in Socal and the skip was in, I used to talk to my friends in NE Arkansas every day on 26.955. One day a contact asked me if I had FM on my rig. I said yes, and he said let's try it. Amazingly we were able to communicate just like on AM. This was weird because I always thought FM was line-of sight only. Can anyone explain to me how this happened ??
. . . And BTW, what is this discussion about the legality of PL on 11 meters ?? It's just a lo-freq tone running under the voice audio. No subcarriers or anything like that. Trouble is ... it requires a repeater to work, and right now there aren't any (many) repeaters on 11M. If the repeaters were out there I'm certain they would be legal, but they would be limited to 4 watts output and would probably require some sort of licensing. With only 4W out, probably not worth the trouble.

People often mistake mode versus frequency because of the common terms AM and FM tend to be related to AM and FM broadcasting. In this case, FM is VHF and indeed tends to be basically line of site. It has nothing to do with FM mode used on other frequencies. My ham gear will run FM mode on 160m and it most definately is NOT line of sight.
PL tones do NOT require repeaters although they are most often associated with them. PL tones may be used with any receiver with tone decode capability.
Capt is correct, we used ht's at one place I worked at and had the squelch set for a PL tone.
There was no repeater only simplex.
It is just another way to open the squelch.
You can have a s9+20db signal, but it will not open the squelch without that tone.
The Johnson call select feature used on old CB radios used a tone to open the squelch.
If it was approved way back then and never prohibited since I don't see it being a problem.
But,
I know of no current manufacture that has this feature included in it's 11 meter products.
Only ham gear. ( or export 10/12 rigs ) modified for running on these frequencys has this capability that I am aware of.

Thanks, Cap. I did not know that.
