TN State Troopers & Mutual Aid

[Julian1]

I seem to recall 460.400 being a statewide mutual aid channel.

Is that correct? If not, what's the latest on that?

Thanks!!!

460.4000Mhz is law enforcement mutual aid in areas where UHF is active. It is used in East Tennessee where several counties use this band. In Chattanooga-Hamilton County, the 460.4000 repeater is still active and available for use, even though local agencies switched from 460Mhz to 800Mhz in recent years. In areas where VHF-hi band is used, mutual aid is 154.755.

As a kid, I remember when 37.26 MHz. was very active. Has this been completely phased out or is it still used for Mutual Aid purposes?

If I remember correctly there are 4 non trunked statewide M/A's

37.2600 Low Band Law Mututal Aid
154.2800 Fire Mutual Aid
154.7550 Law Mutual Aid
460.4000 High Band Law Mutual Aid

Just for the heck of it I checked out how many licenses are issued to each in Tennssee:

37.2600-98
154.2800-19
154.7550-46
460.4000-85

Here in SE TN 154.7550 is the one in use the most.

37.260 is only used in small pockets of the state.

Don't forget:

155.370 Innercity
37.900 Medical Common (called Rescue Squad Net?)
155.205 Medical Common

As for 37.260, my TN travels (mostly west TN) reveal this as for local government and/or fire operations on a local level. There's not any mutual aid ops that I can hear taking place.

Incorrect, their are some law enforcement operations that still take place on this frequency. I hear Lincoln, Lawernce and Wayne Counties when I am in the area transmit BOLO's to each other from time-to-time.

37.900 Medical Common (called Rescue Squad Net?)

This is the State Rescue Squad Net.

Shows you how much I travel in TN doesn't it? :lol: I'll listen out on 37.26 for Wayne & Lawrence Counties from my home about fifteen miles into Alabama. I hear innercity (155.370) more than anything though.

When I was an Explorer with Sevierville, back in the 70's, there was a 155.370 base station that sat mainly turned on, but seldom used . I recall it was a statewide grant to link PD's , station to station and was supposedly monitored by the THP in Knoxville. It had a rotary dial on it in which a list of encode #'s was nearby to tone up the correct agency, much like the HEAR system. 460.4 was on the 4 channel radios but it seemed to sound garbled and not sure if if was repeated back then. 37.26 was a very active freq with 4 or 5 base stations in the county. Station 1 was Sevier Co., station 2 was Sevierville, station 3 was Gatlinburg and 4 was the Ambulance service. It was definately interoperation before it became a buzz word, heck even the tow trucks had it too

Interoperbility was the thing and it was easily done. Now Motorola and MA/Com whoever they want to be today, wants to sell a bill of goods that is even less interoperable. I was an Explorer in South Florida, I moved to TN in 1991 at the age of 16. At that time I can remember that Miramar, FL would always be able to communicate directly to Metro-Dade (now Miami-Dade) on 155.370. The portables all had it as most vehicles were equipped with converta-coms. FHP, Metro-Dade, BSO all had 155.370 and it worked. Now they all have seperate trunked systems that are lot linked. When I moved here in 1991 and became an Explorer outside of Nashville I remember I was told that the Chief of Metro-Nashville at that time made this PD take South Dispatch out and they were no longer welcome on it.

Today Metro is on an 800 MHz digital system with no patches or links to the system. This PD borders Nashville and has no means of direct communications with the wonderful Interoperable 800 MHz Astro system. This PD does not have any portable units and they do not have any digital scanners. Just goes to show you how the simple low band 37.260 did more wonders than a multi-million dollar system.

There is some traffic on 37.260 in some areas of Tennessee. During the summer of 2004, while in the Grundy County (Tracy City-Monteagle) I heard 37.260 being used by Grundy County SO, Marion County SO and Sewanee PD. Sometimes Sewanee PD is heard on 37.260 especially late night and early morning when the students are in college at the University of the South at Sewanee. Sewanee PD sometimes identifies itself as Metro Sewanee when using Low Band.

Seems like Nashville is shorting themselves some by not allowing patches to the system. Here in western Washington, LERN Law Enforcement Radio Network (speaking of 155.37) is patched through on the King County system and in Portland there are similar patches or at least an offer to purchase a radio and get a talk group. (BNSF police and others have tag #s)

Ronal Serpas, your chief was the Chief of the Washington State Patrol before he went back south(previously New Orleans)

Our city, Huntsville, Alabama had a base radio on 155.370 to talk to Fayetteville/Lincoln Co. It was taken off the air several years ago and is now sitting unplugged in a storage room. It is an old GE MASTER EXEC (?)Base with a rotary dial on front.

The city still renews the license - KIB937, probably because they don't realize what it is (was).

Alabama only has 1 widely used interoperable freq. for law enforcement 155.010 simplex, no PL

Of course, some of the scattered around trunked systems have the 800 Mhz. mutual aid channels too, but that is only in a handful of areas.

When I was a dispatcher in the early 1990's we would use 155.010 to raise Ardmore PD (a town located half in Alabama and half in Tennessee) and advise them of the pursuit, BOLO, etc. and they would in turn call Fayetteville on 155.010 and repeat what I had just said. Ardmore had an old VHF Low monitor-only radio on the shelf that they listened to Fayteville talk back to them on 37.26 :lol: Talk about interoperable communications! :wink:

TN Mutual Aid Channels

I recall back from 1973-1977, listening to Lafayette (TN) PD and Macon County Sheriff's Dept on 37.26 MHz. I was a teenager in high school in SC and looked forward to spending holidays and summers in Lafayette with my grandparents. As others have already noted, with a very simple and minimalist system, as good or better mutual aid was achieved with that simplex frequency as you will find on the most expensive 800 MHz system, now. I recall 37.26 seemed to be a common local and mutual aid channel for many smaller, rural, counties and towns back then. I would routinely hear Macon county contact Hartsville PD, Smith County, and Trousdale County on that channel. Nearby Scottsville, KY would monitor 37.26 on a scanner and communicate semi-duplex with Macon County, who monitored Scottsville's frequency on a scanner, also.

Now, Macon County and Lafayette have their own VHF systems. I haven't been back up there since 92, but even then, it was disappointing that monitoring the rural counties was not as easy as it once was.

That is not entirely correct. Metro has (or had if things have changed) interoperability with a few other Davidson County agencies. I do recall that Metro shares access to its system with Vanderbilt and the Airport Authority (both have own PD's) and possibly a few others. I also recall that Metro is/was very picky about who has access. Anyways, you are correct that conventional systems make things a lot easier.

Interoperability

Metro Nashville and surrounding areas just concluded a net on 155.37 at the time of this post.
