To Whom It May Concern:
Kansas City, MO currently operates on an eight site, 24 channel EDACS Analog Simulcast 800 MHZ trunked system that has been in operation since 1993. This system, operating under call signs WPMJ627 and WPMP439 has reached its end of life.
The age of the system make parts either no longer available or hard to come by, which increasingly puts the system at risk of a disruption to Public Safety communications.
The City has contracted with Motorola to replace this system with a Project 25 compliant digital simulcast system that will be expanded to nine radio sites and 30 radio frequencies. Replacing the existing legacy system with the new APCO Project 25 compliant simulcast radio system, will allow a new consolidated frequency plan that will
improve communications through its digital operation, as well as allow enhanced ground communications for fire and police using digital vehicular repeaters.
Likewise, this expansion will accommodate the 6151 units operating for Kansas City, MO, plus the additional 375 units being supported on the system for the Cities of Riverside, Gladstone, and North Kansas City, MO. The system is to be used for police, fire, KC metropolitan ambulance system, hospitals, and other local government and
public safety personnel for the greater Kansas City area and surrounding cities, as noted. It will improve overall communications capability for all public safety agencies, which in turn will greatly support the protection and safety of lives and property of this
large metroplex.
Kansas City has completed its rebanding plan and has received Sprint/Nextel notification that they have cleared the “replacement frequencies” that the City is to
receive through their permanent application filing that is being filed
with APCO under
separate applications. Sprint/Nextel’s letter is attached.
Before the Public Safety users can be transitioned to the new system it must be tested and its functionality verified. In order to facilitate an orderly cutover to the new system in the time frame required by the rebanding agreement this testing had to be constructed. In order to do so, the City of Kansas City, MO
was granted two STAs under FCC Rule Section 1.931.
The City continues to operate under the STAs (Call Signs WQOC757 and WQOC760) that they will continue to renew until grant of their permanent license

I thought we were already on the a Apco 25 ?....Why are they changing the control channels already?..So we will be re-programing KCMO soon? in our scanners?....I know I'm asking a lot of questions sorry...
They are applying for a permanent license for 10 years...before the FCC gave them a temporary license for only a few years once they started the system.
I was studying the site locations earlier, and got it in layman's terms figured out, I think. The sites are all connected via microwave. When someone transmits in the area of a tower they're "affiliated" with it gets broadcasted on each of the other sites on that frequency. With each site using the same frequencies, it's quite easy to simulcast it. They are just thinking it's best for their coverage around the city, that's why eastern Jackson County has their own, but can roam onto KC's, and JOCO, and soon to be Cass County. Cass County will be simulcasted throughout many sites throughout the county.
The lower the frequency, the longer distance it travels; therefore, 800mhz travels not as far as VHF so they need more tower sites. They're using 800 since it's a metropolitan area, but other areas use mainly VHF to get the distance they need which is why the state went to MOSWIN being VHF and not 800mhz (cost efficent too).
Is this all making sense? If it doesn't PM me and I can try to explain it better.
I took the 436HP up I-35 from Franklin County to about 93rd and Metcalf today. I used both the RadioShack 800 antenna and an external non optimized for 800 antenna. I noticed no simulcast errors and everything was rock solid and clear. Most of the KCMO monitoring was from about 135th and Metcalf to 93rd and Metcalf and back South when the KCMO sites were out of range somewhere in the Olathe area. It reminded me of EDACS again coverage wise. The PRO-197 would often fluctuate and drop in and out with pockets of clean decode and broken voice. I did not experience that with the 436. It was rock solid reception the entire way.
Thought you guys might be interested.
436HP for KCMO MARRS site works great downtown, near the Stadiums, 63rd and I435. Also, down at 135th and Holmes. Those last two locations I've previously had the most problems with simulcast on HP1, 396T and PSR-800. After about 10 hours of mobile use with a RS800 antenna, I did not hear any of the usual issues with simulcast.
Does Parkville PD have their own talkgroup? I know they are dispatched by Platte County but if itty-bitty Randolph has their own talkgroup I thought surely Parkville has their own, too. But I don't see it in the database. Anyone know if Parkville has a tg and what it might be? Thanks

Oh man. They have Motorola looking like the bad guy. I thought they were a little tought on them, however they didn't even mention too many competitors. The usual KC Star one-sided story.
