Freeband 11 Meter Frequencies and Bands

Most freeband operators use AM mode below CB channel 1 - the lower bands and SSB above CB channel 40 - the higher bands. There are several exceptions to this "gentleman's rule" however.

While some export radios - sold as 10 meter radios - often cover frequencies above and below the 25.615-28.305 MHz range, that is the de facto "standard" export band alphanumeric plan. Generally the CB band is band "D" or the "mid band". On 120-channel radios, coverage is generally limited to 26.515-27.855 MHz or 26.065-27.405 MHz, depending on the model. Modern Chinese export radios cover 25.615-30.105 MHz to include all of the 10 meter band and frequencies above it.

25.615-26.055 MHz - Band A - often used by taxi cabs and trucking companies (AM mode in the Americas, AM or FM elsewhere)

26.915 MHz AM - Big radios USA "915" channel 36 down one band, AM DX channel

26.965-27.405 MHz - Band D - legal CB band - "mid band", "FCC band" or "CEPT" band

27.415-27.855 MHz - Band E - "high band" or "uppers", mixture of SSB, AM and FM (FM rarely used in North or South America)

27.410 MHz LSB - Often used for SSB in the USA, can suffer from interference or QRM from AM stations on 27.405 MHz (CB channel 40)

27.415 MHz LSB - US calling/working frequencies (channels +5 kHz, 27.420 MHz, 27.425 MHz, 27.430 MHz, and so on, usually in LSB mode)

27.455 MHz USB - Latin American calling frequency (see also 26.555 MHz LSB) - Spanish language

27.775 MHz AM - sometimes AM signals are heard on this frequency and higher during band openings, often taxi dispatchers, etc

27.855 MHz AM - High band channel 40 - popular with trucking companies and taxi cabs

27.855-28.305 MHz - Band F - up to 27.995 MHz (channel 11A) popular with taxicabs and truckers, although truckers are often heard above 28.000 MHz it is strongly advised that freebanders stay below 28 MHz
