What site(s) are you monitoring for Grundy Co Fire? Correct me if wrong, but I believe that 90+% of the time, you'll only hear them on the Will/Grundy Simulcast site. Occasionally, I could hear them (and the Police 1 and Police 2 TG's) affiliate on the 'Cook South - Simulcast site'. Depending on the site(s) and the agency, you may hear them on distant sites due to roaming, testing, etc.
