In addition to CB radios, the Madhatters have made a big push in recent years to get members licensed for using Ham Radio. Ham Radio is a vastly superior means of communication on trips, given the longer range (due to higher power and use of repeaters), and vastly better audio quality. Many members are Technician Class, with several members holding General or Extra licensing (which allow extending band usage, more power, etc – mostly useful for fixed station operation).
CB: Channel 4
Ham Radio: Simplex 147.555MHz
