Repeaters transmit between channels 1 and 8 and receive between channels 31 and 38. Avoid these channels for non-repeater (simplex) communications. If you are near the station you are talking to, you should move from the repeater to a simplex channel to leave the repeater free for others who cannot communicate direct.

CB radio frequencies or Citizen Band radios frequencies are sometimes referred to as PRS, Public Radio Service frequencies, or free to air frequencies. As the CB frequencies are free to use, there are a number of conditions to adhere to when using these radio frequencies. An example is that radio output is not to exceed 4 watts on AM CB radio frequencies and not to exceed 5 watts on UHF CB radio frequencies.
