Hi UHF-LOW,
Here's what I answered in private to another member (Would it be you on another alias ?!?) who asked me a very similar question yesterday. Here's the resume : "If I wanted to program Longueuil fire dept what site would I use.?"
Main dispatch being permanently tie to RSP site # 1, you'll get 80 % of the air traffic. Other to consider, are sites # 5, 8, 26 and 30 especially 8 and 30.
RSP # 1 and 8 should bring you 98 % of the traffic. If you missed too much, then add 30 and 26.
Good luck
RSP # 1 being a simul-cast (3) sites and having one site very close to the south shore on the Montreal side (Surete du Quebec headquarters building) is the main site to listen too.
I listen to it after programming it with Win500 thru RR download and everything is fine. Might need to look at some fine tuning ... Make sure you download all the frequencies and not only a CC (altough it's a Moto option) and FD TG's and check the appropriate option for the wildcard to begin with ... Then, not sure if it has an incidence or not but have you check the "allow 5KHz option" ? I know that for me in some system it did ...
