I would have to agree with fineshot1 in regards to the available channels and channels that are rarely used. Not only do the departments have access to the 5 Zone Talk Groups, but also 5 conventional fire repeaters, 2 simplex fire ground channels, and 3 Tac Talk Groups. That's 15 available channels. Although County can't monitor the simplex FG channels, they can be used to free up a TG or conventional channel should it be necessary, which is done now from time to time. Also thrown into the mix is the fact that the Zone 3 Talk Group is always available as there are no FDs on the trunk system that are assigned to it.
One thing I have noticed, and it came to my attention last night during a major structure fire in Lavallette. It appears that there is no single channel on which all departments, both County and self dispatched, can communicate on during a major incident, such as the one last night. Stations 27 (Ocean Beach), 28 (East Dover), 35 (Mantoloking), 44 (Seaside Heights), and 69 (Lavallette) were all operating at the scene. 27 and 28 were using Dover Twp. Fire 1 and 2, 35 was using the Lakewood Conventional Repeater, 44 was using the Dover Twp. frequency as well as their Zone 2 low band fire ground frequency, 69 was on the Fire Zone 1 TG, and the Fire Coordinator was using his TG. Low Band Zone 4 was also used. Being that Lavallette was command and on the trunk system, coordination was difficult for their chief, the actual Fire Coordinator, and county dispatch.
After the fire was extinguished, I heard the county dispatcher and the Fire Coordinator discussing this, and the dispatcher was reeling off all of the channels that were used and said that communications and coordination would have been a lot easier if there had been one channel on which everyone could commuicate. That might be something for the powers that be at county to consider. Just my nickles worth.
