155.475

[radioboy75]

The Sioux Falls SD TRS system has 155.475 listed as one of the digital voice channels.

Surely this cannot be. If they ever did key up there, they'd wreak havoc across SW MN and NW IA -- as they use that as an analog mutual aid frequency. In Minnesota it's called MINSEF -- the statewide emergency frequency. In Iowa it's used between agencies to coordinate emergency response.

Could it be that this is ACTUALLY a channel installed for analog mutual aid with out-of-state departments?

Although, I haven't heard any SD traffic on that fq since the days when METRO would send "any unit in position" alerts on it before the digital system . . .

With Sioux Falls edging ever closer to the IA and MN borders, it would sure make sense to have a liaison frequency . . .

For that matter, MN is moving toward the 800 MHz Digital Trunked ARMER system and Iowa is looking at a future 700 MHz system. But no one seems to be talking out-of-state interoperability . . . a big thing in my area . . .

When MN gets up and running they will make a patch of some type to patch a talk group together with MN.
unless all departments go to the apx radio that will do all bands?
I know SF Fire has some Apx Radios. but they are used only for the digital system in SD.
Not sure what will happen with IA and SD. as for now we have there 154.160 programmed in our FD Radios so we can still talk to them. and Luverne still have vhf that we can talk to with the Fire Depts.
as for law enforcement to my knowlage they can't talk to each other on either side.

We have a local Task Force who is using Mutual Aid as a digital channel. I thought Mutual Aid should hands off except for Mutual Aid!

Scott, it gets better.

At one point early on with the system, 155.475 was that site's alternate control channel. It sucked down here when the band was up.

My bad, I was thinking of 155.700 which is still listed as an alt cc. That's an ISP LEA freq. in many parts of Iowa.

What do you mean nobody seems to be talking out of state interop? I know lots of high level people in NE SD and Central Mn and SW Mn that are discussing and planning for interop.

Sorry for resurrecting an old thread, but I don't get to the forums much.

I mean in the SD IA MN tri-state area. The best way for our dispatch in Lyon County Iowa to reach Sioux Falls Metro is on the PHONE. That should not be. Public safety comms should be independent of the phone system.

Our county used to use point-to-point -- 155.370, but I don't think that's in use anymore in Sioux Falls.
