    FWIW:

    Here's the Class License
    "Operation of a CB station must only employ FM or PM with a transmitter power not exceeding 5 watts pZ with a necessary bandwidth not exceeding
    16 kHz."

    Also the radio itself must comply with the the approved standard which most commercial units don't. (Even though it could be argued that they are of a higher quality.)

    More stuff here too:

I like to monitor emergency services and find the 450 -520 (UW Band) is the most versatile in this regard).

    They're a great radio and these days dont cost any more than a basic 5w GME (often a lot less) yet the construction and features are so much better than the 'CB' radios even though they were built about 15 years ago. They are still in use by many companies and councils, although emergency services have phased them out with perhaps the exception of rural fire brigades who keep everything for much longer than everyone else.

    I'm an advocate of the extra power when needed, primarily when using repeaters. Often it makes the difference between being able to access a repeater or not. I agree its not necessary for convoy type use.

    Hi from NZ!
    These radios show up here from time to time, is there a specific model you can tell will cover the bands you use yours for?
    Thanks

    This link: PRM80 mods & information: PRM 80, PRM8030, PRM8010, PRM8020, PRM8025, PRM8040, PRM8041, PRP80, 8010, 8020, 8025, 8030, 8040, 8041 Philips Simoco Radio mod should help.


    I prefer the UW band versions (450 - 520 Mhz) as it works for UHF CB and emergency services frequencies (programmed for recieve only)

    Thanks Mark. That website seems to be permanently down though.

    I have a PRM8030. What antenna do you use?

    EDIT - OK - found a copy of the web page you posted
    http://tas.wicen.org.au/Resources/PR..._esentials.htm
    very helpful

    I have a W4 However when I bought it I was told it had been modified to work as a CB. Guess I will have to test it...
