OK. Time to add my 2 cents...
Back when I was in the two-way radio business, I used to go up to Bald Mtn. a lot - we have a system there as well as another customer. On the drive up Bald Mountain, close to the summit, there are 2 houses. One is a very nice elderly couple that I have stopped and spoken to from time to time; he is an amateur radio operator. Across the access road is another house. This house has a lot of VHF or UHF stationmaster antennas on the roof. In the driveway from time to time was a pickup truck with a security service name on the door (I don't remember the name). But what I do remember is that the phone number on the truck started with a 973 area code, and the truck had New Jersey plates. In passing conversations with another technician, I was told the owner of that house owns a security service company in New Jersey. Also, on the access road up the mountain, there are a bunch of sensors and cameras, which that person had installed (due to problems with unauthorized persons going up the private road towards the summit).
If I get the chance to go back up Bald Mountain to work on anything, I will make sure to pay attention to the pickup truck in that driveway. I'm starting to think that 158.400 transmitter is at that location on Bald Mountain - the signal is very strong from my location in Latham, and the summit of Bald Mountain (along with those houses) are in plain sight from my location.
