OHP Low-Band Base Relays

[Gilligan]

I see that there is a new entry listed in the database for OHP here in OKC. It says that there is a low-band base relay on 44.70 w/ input of 155.31 (71.9 PL) for Troop A. Knowing that they use the DPS 800 Mhz system for dispatch ops and low-band for alerts and car-to-car, what exactly is the purpose of a "low-band relay"? I thought they were used to retransmit audio from handhelds through the car's radio. But they only carry 800 Mhz handhelds. So what are they for?

Backup, I suppose.

I'll take a stab at it. Notice it says, Base relay, as opposed to Mobile relay, the opposite of mobile relay if you will, wherein the mobiles i.e. 44.9 hit a R, lets use Cresent 155.445 as an example, to relay the 44.9 transmission back to Troop A.
The 155.310 output hits the Remote 44.7 base relays so the units that are kind of far out can recieve them.
Somebody might know more about this than me so don't take that to the bank.
That's just the way I THINK it works

I believe you got it right. Troop A has more than one 44.70 transmitter. I know the Pink site around Highway 9 and 102 has a remote 44.70 transmitter to reach mobiles better in the eastern reaches of troop A. Dispatch transmits to it on 155.31 and it retransmits out on 44.70. I have heard dispatchers refer to troubles with the Pink ( or Tecumseh)relay.

Think of it as an alternative to wireline control of a base transmitter. And, low-band OHP is alive and well in the metro area; many areas still exist where the 800 doesn't get out.

All OHP units and HQs are equipped with low band radios so they will have a radio that will work anywhere in the state. And right now, low band is the only truly statewide network. Troopers need to have the ability to communicate with any troop HQ or any other Trooper incase of a long pursuit, natural disaster or a man hunt.
