That's a fact. The only TGs on the Sky Harbor IR are the ones used at Sky Harbor. I also believe that the Sky Harbor IR is low power. I can only get hits off the site when I'm east of 75th Ave.To the best of my knowledge, the K-deck fire talkgroups are not carried on the North Mtn or Sky Harbor IR's. (Sky Harbor does have it's own Emergency Dispatch and IMS talkgroups, but they're seperate from the K-deck talkgroups.).
