I setup a GM300 for my truck that is wideband according to the model number.M33GMC29C2AA. It accepted all local repeater frequencies in RSS and seems to be working as I can trip them and they sound clear coming in with tones and such. Some of them are like 146.835- and 147.285+. My question is does wide band mean these frequencies won't work? Just got Tech last week and wide/narrow has me confused with spacing vs steps I think..
