Poplar Bluff PD/FD New System

[wb0wao]

Site 3 was solid copy all day here- running around 400 consistently. I was hearing both sides of the conversation. I logged 44 different UID's today. I don't think that the system is fully configured yet - I was getting some "oddities" with the UID's. I would get the organic UID's 1xxx and 2xxx numbers sometimes and then sometimes I would also get the display of Unit xxx - but on one instance it displayed the actual DSN number of the officer - 2304 - and their last name! The only UID's that I have programmed into the scanner is the UID for the PBPD and EMS dispatch.

As for the EMS units, I am getting nothing from the EMS units as to UID. I am hearing both sides there too, and I didn't hear anything on the VHF frequency today. Going up to Bluff in the morning and will listen on the VHF EMS channel to see if they are still operating there.

Since each of the three sites are using different frequencies, even monitoring one site should provide everything on the network. Since none of the frequencies are reused, it isn't a simulcast system. And you would want the units all over the city to be able to hear what everyone else is saying regardless of where they are at. I could be wrong about this, but I think it is 3 discrete trunk systems that are linked via IP and or microwave as there are a couple of dishes on the tower at the PBPD - one pointing towards the VA and the other towards Briggs & Stratton where the other site is on that one water tower.

As for EMS and Fire Department, I believe that they are being simulcast to the PD's system... I can hear both agencies on their own systems all the time. Also, I'm beginning to think that Sites 2 and 3 are acting as extender's (for lack of a better description) for Site 1... From where if listen from, just north of the city limits, I hear about 90% of their traffic, all from Site 1... There seems to be a drop off every now and then, but no more that I get monitoring MOSWIN channels.

I agree - I hear EMS on the legacy VHF channel and about 1 second later hear it on the city system. The big indicator for that is that the only UID being transmitted is i2997 and that is for both the dispatch as well as any and all of the EMS units. So TG 110 is just a feed from 152.405. That may also explain why the audio is sub-par.

I haven't heard any FD traffic yet other than a few logged hits.

From the home QTH all I can get is Site 3 but this morning I took my neighbor up for a Dr. appointment and was up there for about an hour and a half. I waited in the car and was able to copy all three sites with 4+ bars on each. I spent a good deal of time flipping back from site to site as I programmed in three separate systems - one for each of the sites. In the 90 minutes I did this, the same traffic was on each system. IMHO, what they have set up is a linked network of three distinct separate sites into a single system. Any traffic that comes in on one site is sent to the other two sites as well. Bottom line is that if you can copy a single site, you will hear everything that is on the system.

Gonna spend the next couple of days doing system analysis of it and see if I can get a good read on what is what.

Then, with that in mind, it would seem that all one would have to do is load the nearest site and not bother scanning the other two. Correct?
