aussie cb is fm 5 watts, repeatears allowed, and located near 477 mhz area last i heard. its what our cb here should have been. usa cb should have never been put near 27mhz in am mode totally defeats the purpose of the service, now vhf murs has come real close to what usa cb should have been. but it should have been 5 watts with bases, mobiles, and ht's no limitation on antennas, digital should be allowed although i think it may be on murs, and use of part 90 radios that are capable of meeting the technical requirements should be allowed as well.
but the usa telecom authority the fcc has been screwed up for so long that we are beyond the point of correcting any of this stuff.
