I've been mostly successful monitoring this P25 system from my home office in Hicksville with a PRO-668 and a Shure UA820 elevated feed antenna (774MHz - 865MHz). This antenna really pulls in trunked systems. However, today I'm having a really tough time keeping the "T" on, it keeps going to "S" and when it does that it just doesn't pick up. I checked to see if there were any changes to the system on RR and don't see anything. My programming seems spot on. Dumb question but could it be the weather???
Saw there was some activity on site 3 on tg 6301. The rid's with hits had conversations and the ones without hit only registered with the tg and did not talk yet. I do not have any info logged on any of these rid's. Does anyone have any of these rid's logged and identified?

It could be the simulcast.
What happens if you don't use the external antenna?
The P25 system is TDMA capable, which means those 8 frequencies become 1 control + 14 traffic channels. That is actually more capacity than the current analog SmartZone primary simulcast cell (1 control + 13 traffic channels), and of course doesn't take into account the other sites/simulcast cells in the P25 system, which increases the capacity even more. 700 and 800 MHz are considered a single band on these systems and the subscriber radios, which means they will have no trouble at all roaming between any of the P25 sites when permitted to do so.
So its 330 am and my kid is sick. But I noticed more freqs on site 4. I do not see a license yet for 853.9. But I am half asleep..

Sorry for the late response. The Shure antenna I have is actually a duck antenna. I’ve been told it’s an elevated feed.
853.900 is not licensed, not pending, and there's nothing in CAPRAD for it either. Possibly just a bad decode since it looks like it never popped up in the Channel Activity window, even though it was written to the DSDPlus.P25data file. I've learned to take stuff like that with a grain of salt, as I've seen DSD+ and Unitrunker both do some strange stuff from time to time.
