Anyone Around N.sioux city,sd *Digital*

[JLM7424]

Ok i travel Up and Down I-29 alot between sioux city,IA and Sioux falls,sd
a week or so ago i put my 396T on close call Search Approaching a stopped sheriff
with a mini van I got a Close Call 161.8900 p25 heard the info on the van Knew it was that sheriff
I though they were on the Statewide SD trs cannot find this as a frequncie in the states system
but i hear Pub safety Traffic alot on it

161.8400 p25
also
161.8900 p25

Anyone any Idea?

its Union co. SD Bordering Clay co.SD area.
Specificaly Elk point,SD.

Lincoln and Union county's are both on the State TRS DG TGRP.

I will enter that into my search bank. See what I can see. Thanks for the find.

ok you can give it a try the Sheriff was @ I 29 n/b mm.18 works in that area i pick it up from the
coffee cup truck stop pretty good with 5db nmo antenna


Coffee cup truckstop I 29 / hwy 50 vermillion.

Anything you get on close call, as you described it, would be the input channel for the repeater. Now, SD got permission to use a lot of odd frequencies on the statewide system, including paging and marine channels. I guess it is not beyond the realm of possibility that they also got permission to use those 160 MHz freqs.

the only problem is i hear 2 way traffic on it .

Hmm, pretty odd. Remember close-call only works over a very limited distance. Basically (in the open) you would have to be within sight of the transmitter. What you describe (hearing both sides) sounds like a mobile repeater. The purpose...you guys are gonna have to figure it out.

ok from what i understand on the gre psr-600 it shows the nac code of trunked voice channels.

So i watched the scanner while trunking went to one of the voice channels it showed ,went to it manualy
it showed a Nac of 0A0 then i been watching the found freq 161.8900 it also had a nac of 0A0
I have heard similar radio traffic on it as the normal trunk system but have never seen it come up as
a Voice Channel .

Would an input channel have the nac to ?

what part of the FCC site could this be searched for ?

Can a state like SD use This Freq without registering and licensing it with FCC ?


BTW my close call is fed from a maxrad NMO VHF cut 155.000 5 dbi

Okay first, in reference to the NAC, I don't remember but there is a default, that may be it. The FCC doesn't store NAC, tones, or indeed a lot of things we scanner folks would like to know...that is why this site exists. The FCC also will not store anything dealing with the Federal Government assigned freqs, which I am guessing this is. As for the use of the frequency, since it doesn't fall within the purview of the FCC then they have little to say on the matter. I am guessing there is something else afoot here...BLM, BIA, or some other alphabet agency at work.

BTW, as far as close call is concerned, the more you feed in the worse it is going to work, remember it works on the difference between a noise floor and spike in the entire spectrum. The higher the gain, the higher the noise floor.

Somewhere in the dusty recesses of my memory I seem to recall that either South Dakota or Wyoming had swung a deal with the Feds to get enough VHF frequencies to make the system layout fly. Part of the deal was the Feds would have a presence on the system. "IF" that's the case, I suspect those specific frequencies would still not show up on FCC licenses.

'course I've been known to be mistaken before. . .

 

[guitarbrian30]

yes feds on tgrps

I have heard the US marshalls/ FBI in sioux falls on one of the newer talk groups. This was a few weeks back. Not sure even what TGRP number they were using.

If I might add something here - 161.860 and 161.890 are still within the range of frequencies that are primarily licensed by the FCC. The federal, NTIA allocated frequencies don't start until 162.0125 MHz, so there shouldn't be any reason to suspect these are being used by federal agencies.

There have been some state operated trunked systems that have used some federal allocations (Alaska and Wisconsin come to mind) but I think South Dakota simply received permission to utilize frequencies that normally fell outside of public safety allocations, nothing federal.

Thanks this is the best yett makes sense i will try them and see if thats what i,m hearing . I,m gonna guess its this one: "308 161.8870 VERMILLION"
