Miami County EMS Ops

The FCC link ULS License - Public Safety Pool, Conventional License - WNWE911 - MIAMI COUNTY EMERGENCY MEDICAL SERVICE shows that it expires 10/2012. This is for the VHF system and listed under many scanner sites as EMS Ops. They may not have transitioned all the talkgroups and users yet.... or they might be using the VHF for an on site local talk-around capability. Just a thought.

OK... before posting I came across this.

MOKANSCAN | Frequencies for Miami and Linn County, KS

It shows a couple TGs on sics.

Yesterday heard JOCO P25 traffic on 31190 Medic #14 was dispatched to the Miami Co SO HQ. Anyone have a fleet assignment for Engines or Medic units? It would be easier to pin down the TGIDs for each fire station.

Could it possibly part of the KSICS system? I see in the database Miami County has a couple of talkgroups there...

I had not thought of that... I assumed that since Johnson County was doing the dispatching that it would be on the JoCo P25 system. Maybe I assumed wrong?

The 154.3100 freq has not been used in a few months. I have heard LifeFlight Eagle attempt to contact MiCo EMS on there and they went unanswered until MiCo SO came on and told them that EMS was on the Johnson County Digital System. All of the incidents involving medical helicopters in MiCo, that I have heard, they seem to use tac 8 or 9 for scene to aircraft comms. TG 30108 and/or 30109. That and special events are the only times I have heard the tacs 8 & 9 used.

I actually have tg 31190 on a list of discovered tgids with "Miami County EMS admin?" written next to it... Never have heard anything that sounds like on scene comms. When I have heard it, the traffic seemed to be strictly move-up assignments and a little talk around between units. Much like an admin talkgroup.

Miami County EMS

To the best of my knowledge, Miami County EMS "Main" and "Ops" are on the KSICS system.

As most here already know, JoCo ECC Dispatchers are handling the dispatching and the dispatch side of the JoCo system's "ECC Main" is relayed on the KSICS system. Johnson County field units are not heard on the KSICS TGs, only Miami County EMS units and JoCo ECC Dispatchers.

The TGs are currently in the KSICS database under "Johnson County Talkgroups" with a note stating "These are links to the Johnson County 700 MHz System", which as far as I can tell is not the case, and the TGs should be under Miami County.

Miami County EMS Dispatch is TG 675, EMS Ops is TG 676.

Edit: Also submitted this info to the KSICS database for clarification.

I recently bought a Pro 18 and I'm having a hard time hearing any JOCO FD transmissions. I'm located about 435 and K32 in Edwardsville. I'm using the 800 mhz antenna. I also bought a pro 106 to see if it was my scanner and no luck. Any help would be appreciated. Are they adding more towers/repeaters?

Have you tried the stock antenna or have you always tried with the 800?

Interstate 435 and Kansas 32 are about 1.5 nautical miles from the nearest tower, northeast corner of Interstate 35 and Johnson Drive. The 800 antenna may be overloading the scanner.

Also might be helpful to try "Analyze Mode". How to: Easier to Read Pro-106/197/PSR500/600 Digital Scanner Manual.

I was up in the area of the Legends shopping center about two weeks ago and while there seemed to be a few dead spots, I could hear most of the traffic from this system. That was with the Pro-106, stock antenna and inside my car, driving down the road.

I will try your suggestions. So you were able to hear most JOCO FD traffic? Thanks

Just to make sure.....

1) You have just selected the Johnson County radio site (disable KCMO site)

2) You are only scanning the JoCo talk groups

Since they've "consolidated" the JoCo and KCMO systems, what gets imported makes for poor scanning of either system unless you massage the setups. You need to treat them as seperate systems. As a rule, you need the JoCo stuff and the JoCO "site" in one system and the KCMO stuff and the KCMO "site" in another. They are not a large shared system.

My PSR800 (brother of Pro-18) scanns JoCo w/ no problems pretty much anywhere in the metro.

This is one of those systems where RR might not provide enough information to program your scanner correctly. They are two totally different systems. They do however share several talk groups. This allows users to roam successfully between the two systems without having to change systems on their radios. This is because the two systems are very close together and share some coverage area.

For anyone who's interested, I sat down with some rare free time and created a Kansas-side trunking profile for the PSR500/600s that I'd be willing to share around with anyone. It has the entire JoCo 700 system, KSICS for Troop A and parts of B, KCK 800, Lawrence, and parts of the Topeka area on the KSICS. Scan Lists are broken down by locality and/or agency (e.g. MARCER has it's own list, ECC has it's own list, Overland Park/Olathe/Lenexa/Shawnee all have their own lists, etc.).

I'm in the process of developing one for the Missouri side as well, but that's a ways off. Shoot me an email if you're interested (brandon dot worf at gmail dot com).

Sadly my reception of my local PD (Shawnee) has only gotten WORSE! I've had to endure watching cops in action on their radios literally a few feet from me and gotten partial, or completely distorted reception. Even have situations where I copy a transmission but not the reply. I assume its all about simulcast and the fact that I'm right here in downtown Shawnee. If I'm over in Westwood I might hear Shawnee crystal clear. I've tried the paper clip, but it really didn't help. It seems that it used to be a bit better.
FYI: Its an old Uniden 396. If anybody thinks a scanner change will help, I'm open, although I really love the size and layout of the Uniden. My hope is that the manufacturers will see a demand and find some tech solutions to help with simulcast.
Yes, I'm frustrated! :-(

I'm not familiar with Uniden but, is your scanner up to date with the latest firmware? If it is, my best guess would be your location is playing a big part in your issue.

Basic Google Earth distance search shows from Downtown Shawnee, I used Johnson Drive and Nieman Road as the location, to the tower behind Shawnee Police Headquarters (Johnson Drive & Renner Road) is 3.20 nautical miles. From the same location in Downtown Shawnee is 3.20 nautical miles from the tower site at the Mission water treatment plant (approximately I-35 & Lamar). And a third site, Lenexa Police Headquarters (W 87th Street & Long) is 3.10 nautical miles from the same location.

With you saying that your reception improves in Westwood, I would assume that is because you are closer to the Mission tower, so the scanner is able to focus its attention on the one site instead of being overwhelmed with multiple signals of the same thing.

Downtown Shawnee just seems to be smack dab between two towers, and within at .10 of a mile from being the center of three towers.

I will have to drive over that way and see how my Radio Shack 106 does near Shawnee City Hall.

Edit: Forgot to include this before... Here is a Radio Reference map of the tower locations for this system. Only thing to note is these locations are approximate, the red markers are not exactly on the tower site. http://www.radioreference.com/apps/db/?action=siteMap&sid=6916&type=fcc

Thanks MadSpleen! I would really welcome your research. The site tower info was unknown to me, although I figured the Renner Road. So they abandoned the old 65th Quivira tower?

I was sitting in the QT lot at 67th Nieman and watched the cops on their radios and only was able to discern maybe 40% of what was being said. Bits and pieces of conversations sure doesn't make for enjoyable monitoring. Maybe next time you're getting gas there? :)
I have the latest firmware, but Uniden hasn't had an update since like 2007.
I'd love side by side comparison of the Uniden vs. the RS units.

Thanks for the interest. I'm open to any and all suggestions. I've been monitoring police since my first RS kit back in 1972. It actually used a plastic board with coil springs that you attached the leads. LOL

Are you using a RS800 antenna? There is a night and day difference between the RS800 antenna and the stock ones that come with a handheld unit.

The other end of that same idea is that too much signal may be part of the problem. With a digital signal, multi-path reception can cause all sorts of problems. If you're not familiar with multi-path, it is basically when your radio is picking up the same signal either from a simul-cast system or from reflections off solid objects and all these signals arrive at the receiver at slightly different times and all out of phase (timing is critical in a digital signal) with each other. Frequently when a new system is set up, the technicians will spend literally weeks "tweaking" the parameters back and forth to get the best compromise between sensitivity and decode. Too sensitive and the radios pick up too many iterations of the digital signal all just slightly out of phase with each other, not sensitive enough and reception slopes off in "difficult" places and transmissions “go digital” too often. If you have one, try a little "stubby" antenna as well as a good 800 MHz antenna and your stock antenna. Try each one for a few days and in different places. Try turning the attenuator on and off on the radio with each antenna. You can get a feel for which antenna works best and where.

If you look at FCC license WQKX487 and WQKX488 you can see exactly where the P25 sites are located. There are only 9 P25 Johnson County system sites. The map referenced above includes sites that are not P25.

Yes, I am and have been using the RS 800 antenna. Not sure about the "stubby" antenna. I'm willing to try one if someone points me to one?

Hey Jack I have not had much luck with my 396t either, but my 396xt works ok in the truck but I have a NMO Mounted antenna. If I am outside then the 396xt works ok with the rs800 rubber duck. The pro 106 works good for me too.

Are you indoors, walking around outside or driving?

Inside some, but mostly driving. Just seems that my reception has gotten somewhat worse lately.
Maybe my scanner is getting old? Needs tweaking?
