I'm 74 with mild heart condition. We frequently travel on jeep trails to remote lakes in the Sierras. I'm trying to insure emergency communications. We have a locator beacon, and I'm studying for the Ham tests but I would like to be able to monitor and, in emergencies, transmit to the Forest Service. I know this is legal, but can I do this with Ham gear? The frequencies are around 168mhz. This seems to be within the range of the dual bands I'm looking at, e.g. Yaesu FT-7900R. I can't find anything about this except that it is legal. The Yaesu specs says it can receive government bands.
