I have posted this question on this forum before, but really havent got anywhere with it. So here goes. My family rides atvs in the national forest, we have 3 atvs and we need to keep in touch with the riders from a base station in case of an emergency or break down. I need a radio that will cover a 20 mile radius in very dense mountainous( deep valleys and high hills) terrain. We currently have motorola maxtracs programed for the murrs frequency that run 45 watts( i know that is a little high ) But those radios just arnt cutting it. I dont know if the old radios are junk or what. Anyway i need help with this. I think i might have to resort to getting cbs with amps. Like i said, these are only used for emergencies. I am only looking to talk to the base station, not the next county. And i need it as cheap as possible because there is a good chance the radio will get wet. And ham radio is out of the question when there is 15 riders. Thanks for the help!
