This is good to know, we had no clue that some of the bands and services had assigned freqs for preps. I understand that most of the freqs on the list can not be just for one stations use but it is nice to know where to go to call for help or listen to be of help. In my opinion cb is useless and full of illegal operators, the same goes for marine with radios in all the trucks. The ham repeaters for seem to be the best for localized 20 mile or so use. I am interested in some of those freqs and especially operating FM mode down in what looks like 8 or 9 meters? Good stuff.
