Is there a forum for "Nerds", that's where it would likely go. At least that's what my wife says...........

Well I just purchased the SDS-100 ....
MWJ, What I hear from some of the fire guys is that all Volunteer departments have 2 talk groups each and the Paid guys have 4 to 6 talkgroups each. So for Anna, Melissa, Princeton and Celina you might watch for more TG's as the system comes more alive.

So with Collin County on the PAWM system, I have a question. The PAWM site and the new PAWMCo site are linked and part of the same system. I am in NE Collin county and could never pick up the PAWM site unless I was in Fairview or further south. Shouldn’t I be able to hear Allen, Plano etc. on the PAWMCo site now? But I don’t. I obviously don’t understand how multiple simulcast sites work. Any inputs? Still learning...
If your experience is like mine, you will not regret the choice. I've had mine since late last spring, and it (and the SDS200 I bought about the same time) has far exceeded my expectations.
Your intel aligns with my intel. I'm working on an update submission that will add a few more of the talkgroups to various fire agencies (along with quite a few Police talkgroups). Still lots more to get though. May not submit the update until this weekend though, I'm going back through some of the recordings of the last few days to re-listen and verify what I am submitting (along with what I submitted last week - and no, I was not the one that submitted the site 2 name change, I was perfectly happy with it as "Collin County Simulcast", and will be leaving it as such in all my devices) is lining up with what is being heard over the air. By my current count, I have 7 PD talkgoups to submit, 6 New FD talkgroups, and a few updates to previously reported ones)
Sometimes, when I'm riding solo, I'll bring one the Unication G5's with some Aftershokz AeroPex(that way I can still hear what's going on around me).
It depends on how they have it set up. The Fort Worth and Denton systems are similar. Typically, you won't hear traffic across multiple sites on the same system. One of the many reasons for a trunked system is to share frequencies efficiently, so there are more talk groups available more often. If the county site was constantly simulcasting the Plano traffic, there would be less open channels for the county site users and visa versa. I'm sure there are some talk groups, like the IO(interop) channels that would likely be heard across all or most sites. Depending on how radios and the system is programmed, there may be roaming, where a user might switch to roaming(automatically) if the radio has a better connection to one of the other sites. In that case, you would hear talk groups being simulcast on one or more sites. There are others here who can explain more accurately and with better authority, but hopefully that makes sense and provides some explanation.
A few of the PAWMCO dispatch channels are patched to the PAWM system, but nothing is patched from PAWM to the PAWMCO. Like stated above there is no reason the tie up the channels with traffic outside of the needed areas.
Actually, Wylie FD Ops 3 (talkgroup 828) is frequently patched over to Lavon FD (talkgroup 1266) on PAWMCO, since it appears that Wylie EMS frequently responds to calls with Lavon First Responders. I've also heard the Wylie Dispatcher on there when the patches are up.
As far as talkgroups roaming from PAWM to PAWMCO, I haven't seen any other than the aforementioned patch since the system went live (while they were still in testing, I would occasionally see radios trying to connect and affiliate with the Plano PD dispatch channels, but were denied, and I haven't searched the logs since they went live).
The subscriber radios are more than likely set up with preferred sites. So the original PAWM users will have 1-1 as preferred site. The new Collin County users will have 1-2 as the preferred site. However when the PAWM users go up north or away from the original system they can roam onto the county side of 1-2. You will probably see some of the county sheriff or constable radios drift over to PAWM 1-1
Im running trunker on both and have seen So dispatch 1, Inquiry and i believe County Fire Dispatch 1 affiliate on the PAWM 1-1 site briefly.
Not sure i have seen any traffic from PAWM users on the CC side 1-2.
But hey they just went live almost a week ago so im sure there will be some more fine tuning and stuff to be worked out.

You will probably hear Plano talk groups roaming to the county once more of the original users radios are updates. Many of the original users are still using old code plugs that don’t contain the new sites yet. Updates are supposed to happen soon. Plano city users that have to work out of city and drive to the north part of the county are still not able to enjoy portable coverage yet.
Fairview PD was trying to use their (Encrypted) Ops channel (1337) tonight, and even dispatch was having issues hearing them (according to the dispatcher when they were moving over to Ops 1). They had to resort to using Ops 1 (1172). I've noticed that only some of the local PD's have encrypted their ops channels (Celina and Melissa being the others so far), so it was likely per department request instead of a blanket implementation, and if they continue to have issues, I wonder if they'll back off of that decision.

Hey uhhh, so I heard from a fire fighter from Lavon the PAWM system had an upgrade and the next day I turn on my scanner... dead silent. How do I reconnect to the new system?
Make sure you have the current control channels and you should be good to go.
PAWM = 853.3 and PAWMCo = 774.70625 (Collin County Site)

That's why. The frequency list on the database says 853.275 is the primary. 853.3 works. Tysm
Its best to put all of the primary and alternate control channels in your scanner for a site. That way the scanner will find whichever one is currently active. The only time I remove an alternate is if there's another system that's bleeding over and causing the scanner to not lock onto the intended system.
Some (non-Motorola) P25 systems will rotate the Control Channel on a regular basis, so you may have a day or week that you wouldn't receive any transmissions, until such a point that the Control Channel rotated back to the frequency you have in your scanner.

Aha. Maybe that's why I can't get the county's P25. I only entered the primary.
For Collin County S.O., Lavon, and the other small towns and cities previously using the county's old system, you need to program the sew PAWMCO site in the PAWM system.
The old 800 MHz frequencies from the old Motorola Type II analog system are not being used at all.

Gotcha! Thanks everyoneFor Collin County S.O., Lavon, and the other small towns and cities previously using the county's old system, you need to program the sew PAWMCO site in the PAWM system.

Also, to clarify, PAWMCo is the official name of the Collin County portion of this system.

This document has many interesting details including antenna patterns pointing into the coverage area (the county). A worthwhile read.

Okay .... So I got my SDS-100 in the mail yesterday and got it programmed and went on a drive. Also mounted to the roof is my new 150/450/758 Larsen antenna (Yes I drilled the hole and used PCTel NMO not a TRAM). WOW - Collin sounds good!!! But, it still DOES NOT carry to the outskirts like the legacy 800 system did. I started receiving it south of Ladonia but I don't get it well until about Bailey in Fannin Co. Then it's in and out down Hwy-78 to Leonard and then it really begins to come in solid south of Leonard going towards Desert/Pike/Frognot areas. It's also kind of sporadic down FM-1827 through Altoga and New Hope but again picks up once your close to McKinney. From Van Alstyne to Howe is a solid 5 bars, drops when your in the TI Valley south of Sherman but picks up in Sherman especially on the west side (Probably the Celina tower). I bet a good gain 700 MHz yagi up about 40 feet would suck it into Pecan Gap better, I'll be trying that soon. Also noted, the SDS did an amazing job on Simulcast VHF repeaters here in the sticks. I have a lot of VHF programmed as single channel trunking systems and this scanner is a Serious upgrade to monitor that stuff.
