Yeah, that needed to be addressed. I guess they have thier own police dispatch although there is not much traffic. Not much goes on there but I think they do share a Fairfax and Arlington County PD channel since they borders on the FFPD Mason and Mclean districts and Arlington Police to the east . Fire dispatch is on the Arlington Co System. Funny but not thought of this until you bought it up but I do not monitor Arlington very much. Really not much goes on in Falls Chruch or Arlington.Falls Church is actually on Arlington County's system. The police department has their own talkgroups and the fire department is dispatched by Arlington County and has been for at 25 years. The fire department can be heard on the Arlington County fire talkgroups. They are station 106 in the Arlington County system. I think the police department abandoned the UHF frequencies when they joined Arlington County's system.
