NYC Signals

NYC stations basically serve all of North Jersey including Sussex, Warren, & Hunterdon. Parts of PA: Pike, Monroe, & Some of Northampton Counties. NY State: West Chester, Rockland, parts of Orange. I'm shocked though, Z-100 went up into almost Monroe, NY and usually after you leave West Milford and enter Warwick after the Greenwood Lake Section it's gone. Surprisingly Vernon is covered too with NYC stations. However I don't understand why they die once you hit Sussex. Why is this?
 
Aren't they broadcasting on high buildings? Why am I able to get them in West Milford no problem even with mountains there and up into the Hewitt section & Parts of Greenwood Lake, NY but not in Hamburg, Montaque, & Franklin?
 
Physics and the curvature of the earth.

The farther away from the signal source you get, in this case an antenna at some 1,420 feet, the lower on the horizon it gets before it finally goes below the horizon.

The second part of it is that the farther away from the antenna you get, the weaker the overall signal is. The mountains in West Milford are a) closer and b) smaller than those in Sussex. There is more refraction over the mountain tops from stronger signals, reflections from the ridge behind it and the fact that you're only some 30 miles from ESB. Go out to Sussex and you're 45 miles from ESB. Signal strength is lower, the transmitting antenna is "lower" on the horizon and the mountains are bigger.

Out in the midwest, where there are class C stations running 100kW at 2,000 feet, they go and go and go until.... they fade for a few miles and are gone. Much different than in the hills and valleys of northern NJ with stations only running 6kW.
 
You are also dealing with co-channel and first adjacents. The more stations they place in an area, the more the receiver will be confused and "lower" its ability to receive other stations within the band in favor of the more local, and relatively stronger signals, nearby.

New York's FM signals are the easiest to see this because they all come from the same place - and they have low transmitter power in relationship to other "B"s.

I lived in San Diego when there was a blackout. The stations on Mt. Soledad were off. The L.A. stations came booming in Downtown where they were normally difficult to receive.

Wait until the next NYC Blackout that takes down Empire, B-101 will be there, and so will the pirates...

sometimes CBS FM can be gotten at the jersey shore, other times it's only static. even in car stereos... I notice it also seems to be seasonal as well..
 
Refraction is not consistent. Hot days refract the least; cold temperature inversions moving in or out cause a phenomenon known at tropospheric ducting which also does the same to TV stations.
