Sorry for the bombardment and I didn't want to highjack the other guys thread about race radios so I started a new thread. Do most moto guys wear a headset in their helmet while racing and have it on listening the entire time and why? What frequencies ranges are used during Baja events? Most of these radios that I see like on Bajaracing gear.com only transmit on 144-148mhz. Is that all we need? These are considered amateur radio frequencies and I'm being told by hammies that we're supposed to have a license to transmit on VHF frequencies even in Mexico. Or are we just running rouge down there like doing 100 mph down the highway and stuff. I'm not saying We do 100mph down the highway, but I know most do. Does Weatherman, Baja Pits, BFgoodrich etc etc operate on the same frequency every year? I'm trying to learn all this radio stuff, researching it, and my head is about to spin off. Just picked up a Baofeng UV-82hp for the rider radio and will be purchasing mobile chase vehicle equipment in the near future. Does anyone know if a 7w hand held 136 to 174 VHF hand held can communicate with Wetherman at 25,000 feet? Wasn't really preparing for the rider to have it on the entire time listening through a headset.
