I have a knob position set up with about 20 commercial business DMR freqs.....just local stuff. Suppose I just want to monitor ONE of those freqs? Is there some way to manually step thru the freqs till I get to the one I want to listen to? For example we had a BIG storm last night.....high winds, trees down, roads closed etc.....I wanted to listen to the local utility company, RI Energy. So when I turned G5 on, set knob to right position, radio scans but no way to lock on or HOLD until theres activity. The freqs in this knob position are just simple UHF non trunked freqs.
