The situation: I live on a mountain that, as all mountains do, has quite a few obstructions in the form of trees, rocks etc. FRS bubble pack radios are just plain too weak to be much use (I do have them and have tried repeatedly, not gonna work). I'm trying to decide on a frequency for our handhelds that we carry when we need to communicate in the wooded areas. Some people tell me to use GMRS frequencies and some say MURS. I'm trying to find a freq that is public, not busy and legal. Is there a range of freqs that I can stay in and find something nobody is using or are there set freqs I need to stay on , etc etc. Fill me in
