I have been scanning through a few DOT frequencies in my county, Cowlitz County and this last snow storm we had I heard a lot of traffic on Clark County 854.3375 and South West Radio 858.2125 and a little on 856.2125. My first question is, does anyone know who dispatches for the dot detachment out of Kelso on those channels? And also those frequencies have what sounds like an open squelch on every channel. I have my squelch set properly,it doesn't sound like that on any of my other local agencies,does any one have a possible idea for why those channels/frequencies may be like that? I have been around scanners for a few years and these are the only ones that have this in my local area.
