    Of course. Amps only care about frequency, not modulation type. You won't need any new equipment. Old CB antennas, cables, SWR meters, everything, will work fine with the new FM CB's.

    But amps won't help you much. FM signals don't "Bend" around the curvature of the earth like AM can. Think about it. Those FM radio stations you listen to are good for maybe 40-50 miles from the transmitter and their transmitter has a 1000 or 2000ft antenna pushing 100,000 watts.

    FM radio stations don't transmit as far as AM because their frequency is much higher than AM stations. Megahertz vs. Kilohertz. Higher frequencies don't travel as far. FM CB will be the same frequency as AM CB, so distance will be roughly the same, with the exception that weak AM signals are usually easier to receive and understand than weak FM.

    Yes but the modulation type will be different so it will not carry like AM. FM doesn't skip. Or at least not NEARLY like AM does.

    FCC approves FM mode for CB radios

    "This is going to bring a lot of good things for professional users of the CB radio band like truckers because a lot times when the skip’s really rolling and the [solar] cycle is at its peak, sometimes it can interfere with truckers communicating up and down the highways. FM is really going to cut that down,” amateur radio expert Matt Kaskavitch explained in a video that went viral on a YouTube channel named for his ham radio call sign K0LWC"

    “[FM] is going to provide for better clarity of signal and better short-range communication without having to worry about people from all over the country and really all over the world when the cycle is at its peak interfering as you’re trying to talk a few miles up and down the interstate,” Kaskavitch said.

    And when 2M opens up during ducting, that can be a blast!
