Fwiw, out here in the Sandhills they wasted their money meeting narrow band by buying crappy analog kenwood portables. Mobiles, I don't know, but the control heads in the police, fire, ambulances are old. No digital in sight. Welcome to 2014. Lol

The State Radio System is late to the game. Many agencies got 9-11 grant money and probably some narrow banding money to update their existing radio systems. Region 26 as an example in central Nebraska added 10-15 transmitter sites improving coverage in the existing service area and expanded their dispatch service to several other counties. They probably had to replace some existing transmitters and mobile/portable radios for narrow banding too. 90% of this was all done before any SRS site was online. I’m guessing a couple hundred digital VHF radios would have been a lot cheaper than their infrastructure upgrades.

Except it wouldn't have been just a couple hundred radios. It would becloser to 1000 I'd guess. I know we have about 25 fire rigs. Then two portables for each. That plus EMT portables, close to 100 for my very unpopulated county in the Ref 26 area. Take that times all the other county/ towns, it's a lot of radios. I guess now that I write this out I understand why they bought cheap analog radios. I do have to say you can usually hit a repeater with a portable from anywhere up here. Of course everyone kept the low band too.

Digital isn't always what its cracked up to be either. I use to be a very big proponet of P25 communications, but lately, not so much.
In a properly built out system - be it trunked or conventional, P25 will reach a little farther than analog due to the error correction.
However, I think public safety got caught up from the manufactures back when cellphones were going from analog to digital and some people thought it was a good idea for radios as well. Digital, in general, has done nothing to enhance the day to day operations. Same with P25 Phase 1 trunking. Phase 2 is a different animal as with TDMA you can actually increase capacity.
There is no reason to purchase a $5000 radio when a $500 one will essentially do the same thing.

I've got no idea about the whole state. I know large portions of north central NE still have 39.9 radios. Generally never used, but it's still the fire depts interop channel. They should go to vtac, but volunteers aren't always up on radios. Another reason why the state win system wont be statewide usage, except for maybe large counties, state etc. rural areas won't ever migrate. Really no need.
Nsp, around here, have no low band anymore. Actually they don't use the radio for much voice traffic, out here. It's mostly message/text.

not to budge in... but most of the tri-cities nsp units have completely abandoned the low band... no more 10 ft tall whips... except for maybe a unit here and there. have u heard any of the c roc calling interop roll call?? interesting stuff when aurora, central city, gi, kearney, hastings all get on one place haha

Has anyone found new NSP's mobile extender frequency yet? You know, like 465.525 of old low band days. They are apparently using 700mhz frequencies for the new in vehicle repeaters.

Yeah, I've already looked at that. NE has a statewide mobile license for all 700mhz public safety frequencies (769-775mhz and 799-805mhz).
ULS License - Public Safety 700 MHZ Band-State License License - WPTZ786 - STATE OF NEBRASKA.
There are no licenses to the state for individual 700mhz frequencies.

Check the 700 MHz low power/itinerant frequencies at the bottom of this page

where are these VTAC channels ive been reading about listed?? i looked in the database under "nebraska" and cant find them anywhere. im not looking for someone to list them, or give me a link to them. Im wanting someone to tell me where (and how) i can find them myself...

For VTAC & other interop channels, go to the main database page with the US map, click on the Nationwide Frequencies tab then click on Interoperability.
Interoperability Scanner Frequencies and Radio Frequency Reference
The 700 MHz low power & itinerant channels, which are often used for vehicular repeaters, are listed under Public Safety on the Nationwide Frequencies tab on the main database page.
For more detailed information see the wiki article http://wiki.radioreference.com/index.php/Common_Public_Safety and http://cio.ne.gov/network-serv/publicsafety/index.html

Most states have a blanket license to operate in the 700 band without having to license each freq with the usual FCC call signs. My guess other than someone reading a radio is to scan the band or use a close call feature near (and not interfering with) a nsp car.

does anyone with a uniden bcd996xt know what p25 tuning threshold decoding settings to use? I read up on how to fine tune the p25 settings but was curious. my settings like anywhere from 8-12, and the voltage settings vary from 1.40-1.44/1.65-66/1.86-88. with error rates from 3-50ish lol. thanks in advance.

I never touch mine and it's always under 10. I'm also about 3 miles from the site

hmmm well being 15ish miles from giltner site, here in grand island... the voltage and error numbers and all that sure do jump around a bit lol eventually they do settle a bit but as soon as traffic spikes, so do the numbers. im too shy to start messing with the manual tuning aspect of it. anywho... thanks for your input

anybody have an idea on what talkgroup "3080" is?? dnt see it listed in the RR database. secondly, ive been hearing a lot of radio traffic re-direct when liscense/records checks happen. no more hearing your neighbors records checks on main talkgroups. bummer. thanks!!
