The East Farmingdale channels are constant carrier up and down links from their low band transmitter on top of the water tank next to Adventure Land. Directional antenns and low power. They operate on their 482 mhz channels. The 453 mhz BCFA channels were set up to handle low band dead spots in the Deer Park district [1-4-0].
What is of the essence here is that for sixty or more years the FDs in Babylon have used 46.34 as there primary comm freq. and that is now changing. I think BCFA should be proud of how they managed all but 2 of the towns' departments radio traffic since I can remember.
