FCC allows CB radios to use FM mode, too

Did you guys hear about this? It's old news but I didn't hear a single thing.

So that means you've got 40 more channels, can buy international CB radios and have more means for communication while larping

    what makes you think you get 40 more channels?
    it's still the same 40 channels, regardless of being AM or FM

      Dude, imagine 40 people are using all the 40 AM channels so you cannot use a singe one to talk to your granny.
      Now you can switch to FM and use its frequency range. Although both use the same frequencies its like having 40 additional channels.

        what?
        you'd be lucky to hear anything when you turn a radio on in 2022 lol
        only time i hear any traffic is channel 6 (superbowl) or channel 19 during skip conditions

        that is not the case, you cannot have simultaneous transmissions on the same channel with different modes

          Yeah... that's complete bullshit bro.
          You can TX on FM 23 to your mom and your buddy right next to you on AM 23 to his girl and there won't be any interferences

            not the FCC documentation, not the CB manufacturers, not the online stores selling radios
            not a single person is saying that this opens up more channels or gives the possibility of multiple transmissions on one channel
            what it does it give better rejection of noise and distant signals

          Perhaps you should get some expericence with an FM/AM CB radio before you start talking about stuff you don't understand.
          I get it, you americans have more than 40 years of AM-only experience. Perhaps that's where such weird ideas come from.

            i also own multiple CBs that have FM mode options

              Don't get mad at me dumbo. Just use two of your FM/AM radios, set one on 23 AM and the other one on 23 FM and try it out if you hear the AM transmission on the FM one and vice versa.

                that's entirely wrong, fm will reject noise and weak signals better than AM, but if the AM transmission is strong, it will interfere, and people using AM will get btfo by the FM signal and not be able to hold a conversation at the same time as the FM transmission

                it gives better noise rejection, it's better for local communication in places like cities where there is a high noise floor

                think he's fucking with you or has bad info because there are edge cases that make it possible but you're correct, you can't just take two radios, put them both on the same freq but AM/FM respectively and key without the signal becoming too large to demodulate by the receiver.
                happy to be proved wrong, learning is fun.

        He's correct. The AM and FM modulation shouldn't technically interfere with each other, even given same frequency.
        Practically, AM should be abandoned as vastly inferior, much like SSB for CB.

    First off, better for HAM general in
    Second, no one's on CB anymore. I use it for long road trips but traffic's almost zero.
    This really should have been done 20-30 years ago. God knows an update was needed.

        The fuck are you talking about?
        AM gets a better range with a given TX power. And SSB (at least in Yurop where we're allowed to TX on 12 Watts SSB instead of 4 FM/AM) means range, range, range.
        Most of the CB stuff here works via SSB these days.
        Does the US have a different power level when it comes to SSB?

          12 watts PEP. You are effectively taking the same power but putting it into a narrower bandwidth and not transmitting the carrier. The sidebands are mirror images so you only need one.

    Using the same frequencies but with different modulation doesn't give you more channels (unless it's something like SSB that allows you to choose the upper or lower side of the channel), just like having people yell across a room in different languages doesn't allow you to have more people yelling across a room simultaneously while still being understood.

      To be fair: interference that really disturbs only becomes a thing at closer distances. So when two radios are on channel 20 and am fm respectively, they probably won't disturb each other, might not even hear each other.
      So both anons here are right and wrong.
      Still its nice to have FM too but I wish we had 80 FM channels like the Germans. Funny thing: guess they'd love to have 80 AM ones too (only got 40). And being able to use 12 watts everywhere, not only in ssb mode, would be nice too.

    Disregarding anything else, I am curious about what range a run-of-the-mill base station in the 30 to 40 watt area might have.
