Monitoring BART P25 System

[footage]

BART monitors: I'm setting up a scanner for an esteemed BART retiree who worked at OCC. My BCD436HP received very well in the stations and trains, but I hear nothing aboveground, even close by surface stations. I've installed the system through Sentinel. Are we dealing with (1) a very short-range system; (2) an "aboveground simulcast" subsystem that's not in service; (3) the usual simulcast rx problem; (4) erroneous RR data for the aboveground simulcast subsystem; or (4) something else? I know the 436 is not the best for simulcast, but I have found it to function decently on other simulcast systems.

Thanks for any thoughts.

Hi, @footage. Can you post the frequencies also? Since it's P25 simulcast, the BCD436HP mite has problems with Simulcast Distortion - The RadioReference Wiki

(3) the usual simulcast rx problem

Current control channel is 851.0375, it's strong in Marin County but my BCD325P2 can't decode it.

If you plan on using the BCD436HP at your Home, you can use a Yagi Base Antenna like this 824-960, 13dBi, Terrawave Yagi Base Antenna will resolve the Simulcast Distortion you just have to point it at one of the sites
