Defect Detector Locations?

Hi;
When monitoring NJT Main Line channel 161.400Mhz from my home in Teaneck NJ, I hear several detectors:
MP 12.6 (signal is weaker than the others)
MP 12.9
MP 15.4
MP 14.6

I assume that these detectors are on the Bergen County line and/or the Pascack Valley line, since these are the closest to my location.

Thanks for your help

What you are hearing is Montclair, Main, Pascack Valley, and Bergen County lines

Is MP 12.9 the Montclair detector? That is the one with the weakest signal. I am surprised that I am hearing one from so far away - but my VX-150 does have an excellent receiver and it is connected to a gain antenna up at 30ft.

12.9 is the Main Line. PVRX1 listed them in order.

OK. Thanks. I'm really surprised to be able to hear the detectors from so far away. Do you know how much power they transmit?
