Right, 50 being default is midline. 49 to 01 is a higher priority as the number value decreases. So 01 is the highest. Anything from 51 to 99 is a lower priority from the default of 50, as the number value increases. So 99 is the absolute lowest priority.
I would assume Unitrunker doesn't care if its a TG or user of it. Whatever has the highest priority will broadcast.
Regardless, this is just another reason Unitrunker is quite superior for monitoring. You can't get this level of detail with any Uniden, GRE, Radio Shark, or other unit.
I love the fact that I can set my local DOT guys to 51 & only hear them talking like CB'ers when there is just no one else worth listening to!
