Thailand only...known as "78 VHF" "78 CB" CB 78 MHz" "78 MHz CB" or other similar names. Used by truckers and bus services in Thailand. 245 MHz CB is considerably more popular. However, the propagation characteristics offered by mid band VHF (66-88 MHz - although this band is sometimes called "low band" by some radio manufacturers) are ideal for trucking, bus services and other mobile to mobile communications in rural areas. The 66-88 MHz band tends to share propagation characteristics of the VHF high band (136 MHz - 174 MHz, i.e. 2 meters) and VHF low band (25-50 MHz, 10 meter local FM and 6 meter local FM). The 4 meter band 70 MHz band has the same characteristics, but is not available in ITU Region 2.

245 MHz CB has more favorable suburban and urban propagation characteristics and the higher frequency allows for use of handheld radios with reasonable size antennas.

78 MHz CB radios must have yellow cases per Thai law.

Thailand apparently has regular 40 channel 26-27 MHz CB, 78 MHz CB and the most popular 245 MHz CB band.

80 channels 78.0000 to 78.9875 MHz 12.5 kHz steps. FM mode only, narrowband FM deviation required. 10 watt power limit.
