Hi, Those are either Family Radio Service (FRS) or General Mobile Radio Service (GMRS), or both as the frequencies overlap. These services are different then the Amateur (ham) radio service. FRS use does not require a license. FRS is limited in transmit power to two watts or 1/2 of a watt depending on the channel. FRS is only allowed to operate in simplex, radio to radio mode. GMRS use requires a license from the FCC. This license fee is $35 and gives one a license good for ten years. GMRS allows for more transmit power, 5 watts for handheld/mobile stations, and 50 watts for repeater stations. GMRS allows for the set up of a repeater to cover a larger area then simplex can cover. Again, this is different from amateur/ham radio, and having a ham license does not give one the right to use GMRS. Hopefully, this is helpful. William Anderson

HI, Look at the Humanure website: https://humanurehandbook.com/ . The Humanure Handbook is available as a pdf download. Likely all you ever wanted to know about composting toilets. William Anderson
