If I remember MS law correctly, Constables in MS cannot receive fees for any actions that take place on a US highway. I think that law was probalby written back in the days when the US Highways were the prinipal highways for interstate travel. I could imagine some Constables setting up speed traps on interstate travel to make a living. I could be offbase on that law being enacted, but that is the only reason I could think of why they cannot receive fees. Or could it be to keep the Constables off the highways and into the remote areas to supplant the sheriff?

Nope constables are not allowed to do highway patrol type functions.. never siad they were. They do the majority of process serving, and getting notices out for the local courts. They do assist in other law enforcement issues and respond to assist other officers. At one time as I stated years ago, they were basically the county supervisors private police forces, but that got killed real fast once all the scandals came out. Anyway back to the discussion on me's. To have a semblance of a reason for discussing constables: Many constables vehicles have the same PS radio systems as all the rest of the LEO's, therefore some have the me's in thier vehicles. Question: Do the Texas Rangers qualify as the Texas Beaureau of Investigations, and do they have me's in thier vehicles, or do they have actual marked vehicles at all?

Mississippi Constables are allowed to enforce the motor vehicle code, they just cannot receive fees for doing so on the US Highway system.

In Houston, Pct. 4 and the Sherrif's office don't get along at all. They are tired of Pct. 4 taking all of their calls becuase of the contracts.

Also, there may be other states, but nobody had them listed in a web page known to google.

I am ultra-new at this, and only know about the BCT8 (2 months) therefore any flame-worthy statements and/or misuse of terminology is due to ignorance...

but I did my own google search (keywords: "Oklahoma Highway Patrol"; extender) and found a page (can we post links?) with a few frequencies for OHP extenders: "154.905 extender; 154.920 extender backup; 159.210 extender input and alt."

I suppose the intended meaning of 'backup' is the obvious one, but i dont have any idea what 'input' or 'alt.' mean in this context. Also, the page (last modified march, 2004) gave some other frequencies it thought were for future extender use. The catch is, it said all of these frequencies were only for troops B and L (I-44 East of OKC, aka Turner turnpike (B) and Will Rogers turnpike (L) ).

I wondered about the page's credibility, as it was kind of weird looking to me-- entire sets of "frequencies" the page had listed were the same as talkgroup id's, but with decimals. For example, it has "42.128 Turner and Kilpatrick Turnpike Units" which is quite similar to the talk group ID 42128 for Turner and Kilpatrick Turnpikes (my favorite ID!!). Can someone tell me if it is normal to have id's and frequencies so similar?

Finally, there were lots of frequencies for "repeaters" -- Am i correct in assuming that these are _not_ the same as extenders, and that they somehow receive signals from a distant source and pass them on to cars further from the source? If so, is there any way to tell which station sent the original transmission?

Thanks for your patience...

Mobile extenders and repeaters are conceptually similar. In fact, I have heard mobile extenders referred to as vehicular repeaters. The main difference is the vehicular part. A mobile extender relays from a car to a walkie talkie. A repeater is on a tower and relays between low-power units of all kiinds.

By all means, post the link. This page you mention sounds familiar, I think I've seen it before.

The freqs you mention (154.905, 154.920, 159.210) are more properly termed mobile "relays", they pick up the low band mobile transmissions in outlying areas and retransmit them to the district HQs on VHF-high and UHF. The OHP also has base relays and full-blown repeaters in various areas. As most of these are also moving transmissions from VHF-low to VHF-high, UHF, and above, they could also be termed "crossband" links.

I've been scanning Oklahoma since 1970, and apart from the units in the OKC/Tulsa metro areas on the 800 MHz, I haven't seen any troopers with mobile extenders in their units. Of course, they have handhelds for use in searches and the like, and I have seen troopers with HTs on city or county freqs, but not the mobile extender-type operation. Not saying they don't have them, but if they do, they are not common.

A "vehicular repeater" and a "Mobile Extender" are the same thing.

What I meant was that a "traditional" repeater, what is implied when someone just says "repeater", is typically on a fixed tower. A mobile extender AKA vehicular repeater is in a car.

It would have been clearer if I had said that mobile extenders are a specialized type of repeater rather than being similar to repeaters.

:wink: No Extenders in use in MA anymore. State Police is 800mhz trunked with 800mhz portables. Not in use for ten years here because of the proliferation of 800mhz portables when they started the long migration from lowband. Lowband is for back up and car to car comm's.

There used to be 350 "rat pack" portables using 154.92 and 155.475 but were only used byspecial units and sgt.

That's "Pack Rat"... as in Motorola PAC-RT (the most common model of MRE/Mobile Repeater/vehicular repeater/whatever you want to call them)
