Johnson County P25 System

[CWR]

I was in Bonner Springs today with my Pro-106 , and I noticed that I wasn't getting any reception on the Johnson County 700MHz system.
I looked at the Radio , and I was getting a signal , BUT , no T was showing , indicating no trunked reception.
Have they added or subtracted a controll channel lately ?
I program my Pro-106 by hand , and ALL these changes everytime you turn around is getting OLD , and taking all the fun out of it for me.
I imagine even IF you're using software to program , having to constantly have your radio hooked up to the computer , gets a little tedious........

Johnson County no longer has a 700 MHz system. All the 700 MHz channels have been removed. The 700 MHz control channels were removed earlier. The system is back to 800 MHz.

BB, that is the plan from everything that I have heard... However, it is yet to happen. I am looking at Overland Park PD on a 700 MHz control channel right now. No one really seems to be able to say when the switch to fully 800 MHz will occur but, it hasn't yet.

I just did a Pro-96com readout and found that 700 MHz frequencies are still being used as MadSpleen85 previously indicated

Not Exactly! Having been up close and personal with the equipment the 700 MHz frequencies have been removed from the control channels on the Johnson County system. We did leave one spare transmitter with the 700 MHz control frequency at each site but it would require the failure of the prime and alternate control channel before the 700MHz control channel would come on line. Unlike the old analog trunking system the control channels do not rotate. The only time a control channel rotates is with the failure of the existing control channel.. And as I said earlier the 700 MHz voice channels are also being converted back to the 800 MHz frequencies as the FCC approves each site frequency modification.
Also, Overland park has no trunk system. Their sites and equipment have been de-commisioned. Overland Park is on the Johnson County System. The Independance system still has 700 MHz control channels and some of the Overland Park talk groups are present on their system as well as the KCMO system.

Thanks for the explanation BB. Do you know when Independence plans to convert their PD/FD over to 800 MHz? I know it's supposed to happen fairly soon.

I'm still catching trunking data coming off of the 700 frequencies on several towers. I'd say someone needs to have a chat with CommenCo about that if the 700s are supposed to be no longer in operation. Also, having had communication with an individual in EM, it sounds like it still hasn't happened yet.

But, also considering that you've said you have intimate contact with equipment and know first-hand, it could just be I'm mistaking it for something else.

On my Pro-106 , it shows the Control Channel as in the 800 MHz's , but the Voice Channel as in the 700 MHz's , off of the Shawnee Tower...........

 

[hkrharry]

Listen to BB.

He knows what the G2 Is.

If he says the 700 is gone on JoCo it is gone....

If you read my post again I said the 700 MHz CONTROL CHANNELS are gone. Eventually as we change each repeater back to 800 all the 700 Mhz channels will be gone. Currently we are about half done pending modifications to licenses and hardware. So you will still hear voice traffic on 700 Mhz frequencies. The moral of the story is to be sure you have the 800 MHz control channels added to your scanner.or you won't hear anything. Sorry for the confusion.

hey guys and gals. still new to this site and needing some help. i have a BCD996xt i have gotten it programmed but i need to know if i need a custom band plan for Johnson County? because i cannot hear anything on my scanner.

 

[Jack007]

Maybe a dumb question...?
Is there a problem if you have freqs programmed in that have been decommissioned?
I haven't removed any of the 700 ones; I just added in several 800. That may have explained why it was silent sometimes, even though I knew for a fact they were transmitting.

No, program it as a P25 system. The radio will take care of the rest. It's a gawd awful system with simulcast errors out the *** so you mileage may vary.

okay thanks. i do not know why i cannot get anything to broadcast then. every time i try to program is it gives me the error "error setting band plan on custom search" but on the scanner it will still search the frequencies but nothing comes through. any ideas ?

I'm curious, did you pay someone to program the scanner? If so, I would be looking to that person/business for assistance, since their programming didn't work. Or did you program it yourself?

If your unit was programmed correctly, all you should have to do is turn it on and be able to hear radio traffic.

no i didn't pay anyone to do it. I did it myself by following the instructions another member on here gave me. it comes on and scans the channels i programmed just i do not hear anything

 

[BigC801]

Zip up the file you have and post it.

 

[Jack007]

Okay.
A plea for help!
I posted above asking about programming in additional (extra) frequencies and what effect, if any it would have on reception.
Since no one replied, I went ahead and added the frequencies I saw missing.
Now it seems that my reception is worse; as in missing transmissions.
Can someone please answer my query, and more importantly, point me to an exact and complete list of frequencies that need to be programmed in order to properly monitor the JOCO system?
I am thoroughly confused and totally frustrated.
Thanks so much,
Jack007

Try This. Enter only the 800 MHz control channel frequencies. There is usually a prime and alternate. The control channels don't change unless there is a failure of the prime control channel. (If you are using control channel only decoding then you are finished entering frequencies--now go to scanning). You can enter all the rest of the 700 MHz and 800 MHz VOICE frequencies if you want to. It only takes up memory space.

WA0CBW can HP-1 monitor this System.. Thanks b780
