Brazil allows higher power levels than the US and most of Europe. New Zealand has two 40-channel HF CB bands available, the NZ-specific "NZ CB Band" 26.330–26.770 MHz (40 channels, AM and SSB allowed) and the standardized "mid band" 26.965–27.405 MHz (40 channels, AM and SSB allowed) for a total of 80 HF CB channels.
South Africa has a 23 channel AM / SSB 29 MHz CB allocation (called "29 Megs" or "29 MHz CB") from 29.710 to 29.985 MHz in 12.5 kHz steps. South Africa also permits use of standard CB channels 19–27 (27.185–27.275 MHz) with AM / SSB permitted. Many radios sold in South Africa feature both the 27 MHz and 29 MHz bands.
As originally constituted, what is now CB radio was Class D of the Citizens' Radio Service. Classes A and B were in the UHF radio band and served a similar purpose as Class D while Class C was interspersed among the current CB channels and used for remote control of devices, usually model craft (aircraft, watercraft, or road vehicles).
525–1705 kHz in N. America, Australia and the Philippines. amplitude modulation (AM) medium frequency (MF) Usually speech and news, where a lower bandwidth will suffice; long range at night due to the ionosphere increasing in altitude Shortwave: Multiple; see Shortwave bands: Mostly AM and single-sideband (SSB) modes high frequency (HF)
Also, it is only by using these exact frequencies that there will be enough room for four simultaneous SSB conversations without mutual interference, assuming the 2.8 kHz de facto standard bandwidth of typical SSB transceivers. WRC-15 frequencies, like all others, can only be used when they have been licensed for amateur use by a country's ...
Motorola TA288 PMR446 licence-free radio Motorola TLKR T40 radio tuned to PMR channel 1. PMR446 (Private Mobile Radio, 446 MHz) is a licence-exempt service or UHF CB in the UHF radio frequency band, as personal radio service or citizens band radio, and is available for business and personal use in most countries throughout the European Union, [1] Malaysia, [2] and Singapore.
The carrier frequency is 1.25 MHz above the lower edge of the 6 MHz wide channel. This effectively makes the system AM at low modulation frequencies and SSB at high modulation frequencies. The absence of the lower sideband components at high frequencies must be compensated for, and this is done in the IF amplifier.
