RID Late to Display

[ki4hyf]

I noticed an unusual (to me) action on one of the systems I monitor; the UID/RID is delayed almost a second before displaying when a transmission starts. I've looked at several other systems, and it's the only one that displays that behavior. The system I'm talking about is my city's public service system. The RR URL is : Jackson Public Safety (P25) Trunking System, Jackson, Tennessee

Despite what it says it isn't a Phase 2 system...yet. I've never noticed this before, and it doesn't appear to affect the transmissions. I just wondered if this is a misconfiguration or is it expected behavior? I only have one other simulcast system in my area, and it's a single-frequency P25 Phase 1 system. It's really no big deal, I was just curious.

Late to display on portable radio, mobile, scanner?

I've seen it on a portable (ATX4000), scanner (SDS200) and SDR + DSD. DSD+ Fastlane displays the RID immediately, but others don't. I get a decent signal, so I don't think it's that. Thanks.

Is your digital modulator set to CQPSK?

Is your digital modulator set to CQPSK?

Yes. The audio is horrible when it isn't. This behavior also occurs on my friend's city-issued police APX4000. I don't know about his patrol car, I'll look the next time he comes by. My other friend works for the city's park dept., but I haven't had a chance to look at his radio. I've found a "late entry" option in the CPS when I did a search, but from reading about it, I don't think it's relevant.
