I have had a Uniden SDS 100 since October 2020. Since I am fairly new to the scanning with talk groups and systems, I entered my postal code and Simcoe County was loaded from the RR database. When I was reviewing a couple of frequencies, I noticed not only did it not load all frequencies, mostly DMR. So I went through all the channels and had to add or edit channels. Some frequencies I have no idea where they got them from. Just saying check channels and frequencies
