The license from the original post is part of the "Bergen County Alert" radio system. You can tell the original T-Band licenses because they were three letter, three digit callsigns starting with "WI" that were pulled out of the regular sequence (they were issuing four letter three digit callsigns starting with KNA). It was the former "Channel 3" in the County's system circa the very early 80's (I'm thinking 1981) and replaced KEA334, the Plectron system on 37.38. When I got my first non-crystal scanner (a Bearcat 210 around 1977), 37.38 was one of the most active frequencies in it.
The original T-Band County Alert system was built out by Henry Bros. when they were the Motorola shop in Bergen County. The system consisted of Stag Hill as the primary site, with other sites in Palisades Interstate Park and Hackensack. The system set up Mocom-70 consolettes at each police department in the county with UHF yagi antennas, and Motorola monitor radios (they looked like Plectrons) with 2-tone decoders in police supervisor vehicles. Certain agencies got Maxar radios for vehicles. The antenna supplied was called an "oil derrick" because that's what it looked like. Those banged around and broke pretty frequently, and had coax cable with Teflon insulation which would get cut pretty easily with all the usually junk in the trunk.
Even though it was pretty ambitious, the system never really took off. In the beginning, it was mostly coverage related (the transmit sites had to be 40 miles away from Nassau County, hence the Stag Hill transmitter with corner reflectors pointing back into the county), but SPEN started up about the same time and did a better job. By 1987 many of the mobile radios stopped being remounted in new cars (or were damaged by having been mounted, dismounted, and remounted in several generations of cars) and the Mocom-70 control station consolettes were more or less left unserviced by individual agencies. I didn't see much of this past then, and by the early 90s, it seemed like there was none of the originally intended activity on these at all. Funny, I remember hearing MANY alerts on 37.38, but can't really remember one on Channel 3.
Channel 3 eventually became co-opted by the Sheriff's Department for various stuff.
Trivia question - how many Plectron tones were usually sent on 37.38 when there was a countywide broadcast? What seemed to be the most frequent broadcast?
