USA Public Safety - McCurtain County

There are 22 fire departments in McCurtain County. Apparently every one of them has a VHF highband repeater system - each with their own unique channel pair.

The county also has some VHF repeaters licensed on 155.175 and 155.385. And the county firefighters association has a repeater licensed on 154.7625.

All fire calls might be dispatched from just 1 dispatch center. Does anyone know how that dispatch center accesses the 22 different repeaters? (if they have that capability)

I believe they do have that capability. I stayed up there for about a week a few weeks ago and ran my remote monitor program the whole time. Unfortunately I only heard the central dispatch tone out one department during that time. I'm guessing they can probably do it for all of them though. I'm going back for a few days next week and hope to gather more info.

hi mikeB thanks for the reply

I dug thru the info at FCC Licenses and Scanner Frequencies for McCurtain County, Oklahoma (OK) a little more trying to find any indication of linking repeaters or such - dont see anything

Here is the rest of the possible public safety channels that I see listed in McCurtain County

Choctaw Nation - repeater sites at Idabel and Battiest - 151.415 R - 156.105 R - 156.165 R - 158.73 R - 158.7525 R - 159.405 R

Idabel - 155.925 R - 155.52 BM

County - 155.175 - 1 repeater at or near Broken Bow

County - 155.355 - 2 repeater sites - Broken Bow and Idabel - RRDB shows this as EMS

County Sheriff - 155.085 R - maybe 1 or 2 repeater sites

OK DPS - 44.70 R - 154.695 R - 154.92 R

OK DOT - 151.025 R - 151.0325 R - 151.04 R - 151.10 R - 151.1075 R - 151.115 R - 151.1225 R - 151.13 R - 156.1125 R - 156.1275 R - 156.1425 R

OK DOT - TRS - 151.265 T - 154.37 T - 154.845 T

OK - 44.64 - 44.84 - 44.96 - 45.04 - 467.525 link - 770.10625 etc

-----------------

maybe the various FDs are actually dispatched via telephone - maybe the sheriff dispatcher dials into the local FD repeater via telephone and activates their pagers

or maybe the various FDs have "store and forward" repeaters listening to 155.175 (if that is the real FD alert channel) - a FD page would go out on 155.175 and then gets repeated onto the local FD repeater by the 'store and forward' device

or maybe every FD has pagers on 154.7625 (the county fire association channel)

maybe the fire pages actually go out on a talkgroup on some TRS

???????

I heard them dispatch out Eagletown FD on the Eagletown fire channel so that's why I think they can probably do it for all the other departments, at least the smaller ones. More monitoring confirmation will be required though.

via eDispatches.com call log I heard "911" page out Wright City FD to a house fire at 2146 pm (?local?) on 8/12/2021 - some feedback heard

8/13/2021 - 2339 hours - "911" paged out Haworth Fire for a tree across the road - on this call a Haworth Fire unit acknowledged the call and then "911" told him that a deputy was also enroute for traffic control - therefore I guess we can rule out the use of "store and forward" repeaters - there was no indication of that

on both of these pages - someone acknowledged by radio within 10 seconds - the signal is strong - no static over the dispatcher at all - no linking tones or klunks are heard - pager tone is heard also

bottom line - still have no idea how "911" manages to access approx 20 different repeaters around the county - I suppose the easiest way would be to give the dispatcher a 150 foot antenna tower and a selectable frequency control station (FX1) that can key up the various repeaters - in which case, anyone near the county seat might want to listen to the input channels of all the different repeaters

I'm pretty sure central dispatch is using a multi-channel VHF radio to tone out everyone. It's done differently in other jurisdictions. Where I live the County has four repeaters scattered around the county that simulcast. They page out each department on these repeaters and then the departments can switch over to their own repeaters for fireground activities. I work in Collin County where they have a large P25 system and they alert the various fire departments on their own TGRP's.

I'm guessing you are located in or around McCurtain County? Put in 771.08125 in digital mode and see if you can confirm OHP is using it. They are using a NAC of 50 in all of the other Troop E 700 mhz repeaters and I think it's the same there but I want to confirm it. I've received one hit on my monitor program but there wasn't enough radio traffic to verify. I can only hear them from my location when the conditions are right. I'm coming back up there Monday through Wednesday and will try to confirm that and the CTSS tones for more of the rural FD's.

I was finally able to confirm that the 771.08125 OHP repeater is NAC 50. Now working on the tones for the various rural FD's.

I am near Boston Mass so I cant listen in. I found a newspaper article about a new fire station in Broken Arrow, but I wrote it down as Broken Bow. And that led me to McCurtain County after a fair bit of confusion. Seeing 20 different VHF repeaters in McCurtain County caught my eye.

Just checked Call Log – eDispatches - there are no entries for McCurtain County at this time. That tells us that the eDispatches index will hide a county name if there have not been any pages within the last ?24? hours. But they will pop up when a page goes out.
