Will this be system wide, all police and fire in the county?

Is this going to conventional or a trunked system, will they still use P25?

This will just be for the dispatch notification system for the county fire departments only. Radio traffic and dispatches will still be on the 800 MHz P25 system, but the dispatch tones and voice will be simulcast on the new frequencies (East/West) instead of the current 33.9 MHz for the entire county. They also use the old system to release the Knox Box keys.

Thanks

The plan also is to permanently patch/simulcast the 800 dispatch talkgroups and the UHF dispatch channels. FD East/East UHF and FD West/West UHF. The tones are also being restructured.

Is the lowband frequency still in use? According to the timeline it looks like it should be decommissioned by now. It was a great indicator for the North Eastern US for low band skip.

Last I heard the implementation has fallen a bit behind schedule. They are testing the UHF channels still and 33.90 is still in use. I would expect a switchover to UHF and abandoning of 33.90 in the next couple months.

 

[kc8gjh]

They have been testing a single tone quite a bit on both 460.300 and 460.500 over the last couple weeks or so. They have also been testing some dispatch tones. I have not heard any voice yet on either frequency. I have been monitoring both with my Pro-106 and on some days there may be a PL tone (167.9 is what I saw) with testing and other days there isnt a PL tone.

Bad news for those of us who use 33.900 as a band opening indicator. They have a great signal into south Texas via E skip during band openings.

Yep, those days are finally coming to an end. Catch it while you can.

 

[scannerboy02]

I have been hearing voice testing over the past few days. They are using mutual aid 8 and 9 on the P25 system for coordination.

 

[radioscan]

August 29 is the planned on-line date, at that time low band tones out will no longer be.

once this becomes working i should be able to hear it in butler county right

You should not have any problems receiving it Matt.

The latest I have heard from Todd is that Moto Tech's are having issues with some of the sites which as caused a delay in them switching over. He's hoping they get the issue's resolved soon so they can start switching.

i have programmed several new pagers for many of the many fire departments, i was also told that do to some issues at a few towers that they have postponed the switch over till a unknown time,

 

[zerg901]

Seems to me that the paging sequence on 33.90 always followed the same pattern - 1 long tone followed by a bunch of shorter tone sets. What was the long tone for?

 

[swstow]

long tone = dept
short tone = fire,ems.recall or all county

 

[scannerboy02]

Hearing some more testing today.

 

[radioscan]

I am hearing dispatching this morning on the
new Hamilton County Fire Dispatch Repeaters.

I copied one dispatch on Hamilton County East 460.300
with a good tone of 146.2, subsequent dispatches have been CSQ for both.

Fire East 460.5000
Fire West 460.3000
