I hear the PD on 158.835 with very little on the 800. The FD/EMS gets dispatched on 154.100 by the county and they sometimes self dispatch on 154.100 with a weak signal on the mainland. Any FD comm's I've heard have been on 156.24. I've only heard the EMS on 158.835 with limited activity.
I know this an old thread..but just so everyone will know. We will acknowedge calls on the 800 mhz from Ottawa county, and that is it, when they tone us out. Otherwise we self dispatch. The dispatch frequency is 154.100. The rest of our traffic is all on the VHF frequency listed for us. We also use Marcs for Lifeflight comms.
I confirmed them this weekend... I'll submit to the database so others will know.
Possibly related question... Catawba Isl FD had a water rescue on Saturday. The CG picked up the patient and was bringing him to shore. But Catawba couldn't talk direct to them so everything went through dispatch(es) and it took a while, plus was confusing. Why wouldn't some of the FD's that deal with lake issues have a simple marine radio?
Although it may not be too simple - one of the CG units on Ch22A was either encrypted or digital (or both.) I didn't have a digital scanner with me so unsure.
