I put EXTRA FREEKENSIES on my galaxy 2547 today, just because i have that kind of time and my cobra had it and i found the mod and was like oh what the hell why not. and now it goes all over the place i believe 26.6950 to 27.9650 or something like that anyways if you have a galaxy 2547 and know how to decently solder its easy as heck. just do the mod from CBworldinformer. get yourself one of those 6 posistion switches from radioshack for like 2.99 wire it up and its a piece of cake. but i must ask DOES ANYONE TALK ON THOSE EXTRA CHANNELS????? i dont really care my radio is usually parked on 27.3750 all day. anyways see ya
