After the water main turned plastic, the phones became unusable in building. Smart guy figured out lack of phone ground connected to fence. Better but let's drag a few from fence to RR track.
CSX guy called me assuming I was again to blame for his woes. Before he accused our paging transmitter over modulated caused his woes (using an analog meter on a wavetek is not the way to measure rail-rail pocsag)
It seemed that the signals on either side of station would latch randomly and the track tone was modulated with Jones radio programming.
AM/FM same town same owner different towers same commercials same feed.
We owned Tower FM was on. I did service FM licensee son operated AM.
I shut down FM. Guy calls me lying SOB.
I had to go over and hear the singing track myself before dude stroked out.
I didn't even get to hear the modulated track. The 50' of 00 streched across grass. Didn't look right to me.
I suggested that he find a different ground for floating section.
After a polite letter to CSX suggesting radio tech have supervised cross-training attached to my 1500.00 invoice. (Pain and sufferage) prompt payment, idiot probably promoted. And signals worked well.
Conclusion: Not all track is grounded. And once you get a Railroad Job you are set for life, no matter how unusually intelligent you are.
