Soooo I've live in NY, more specifically Westchester NY and i have an SDS200 uniden scanner, I'm trying to listen to the Metro-25/ MTA MRRS system, it's a trunked p25 digital simulcast system from my understanding i downloaded straight from the RadioRefrence website via Proscan. The talk group specifically under the system I'm trying to listen to is (Port Chester PD DSP) also downloaded straight from the RadioRefrence website via ProScan. The issue is I'm not receiving anything. I've tried low squelch, high squelch, stock antenna, glass mount antenna and even a roof mounted antenna on a building all with no luck. Now from what I'm being told not sure if this is correct is the department I'm trying to get (Port Chester PD DSP) that use this system radios run off cellphone signal and are LTE. I'm unfamiliar with this type of system if that is the case and curious what i need to do to get them on the scanner. I'm lost trying to program this unit.
