A new development in this radio story, It looks like that this house is semi known among the Urban Exploration circles, Today i found another youtube channel called Abandoned NorthJersey who has made over 6 videos over this house divided over the last 3 years. Here is a video where he shows another piece of that set up hidden in a corner. it is a audio amp that feeds the transmitter, you can see it a 6:27 in the video from jan 2020

Decojoe67 you were right about it looking like it is on display! the reason everything looks so set up is because of the number of Urb exp filming the same house over and over. 2 years earlier A.N.J. sets three of those pieces together for filming. you can see in a video from 2017.
