Question on Gmrs radios.. They had one I was looking at at wal-mart that was gmrs.. But it was only rated at two miles also.. So if the power out is under 500mW you wouldn't necceserialy need a liscense, right??\
No. You need a license for any radio that has the letters "GMRS" anywhere on them - regardless of power output or if the letters "FRS" are on them too. See my reply to this same question in your other thread Trying to decide which frs radio to get. I go in to more detail as to why there.
