If you have a GRE/RS/Whistler scannner there is a calculator for that.

I'm hearing a control channel on 172.1375 in Kingman, AZ. According to Unitrunker it is an APCO P25 control channel, System ID A52, Site 002-112. Under the sites tab there are 4 sites, 001-006, 002-069, 002-112 and 002-122. I found this blog post that says it is coming from the Hoover Dam area, and there were no reported users as of July of 2017.

Sorry don't have one so can't help but...
that radio does have Intermediate Frequency Exchange - changes the IF used for a selected frequency to help avoid image and other mixer-product interference on a frequency.

Actual frequency is 167.2125 which is a common FBI frequency.
Thank you. It sounds like a repeater or base. So I guess they haven’t transitioned yet to the new NTIA band plan?

No and they may not have to.
Oh ok. I thought they all had too.

New systems do. Existing systems not necessarily.

BP
Part of a Wide-Area Vote-Scan system [VS13] from Kingman
All the VS13 Repeaters use $710 - there are approx 8 of them from 168-174 Mhz

Ah thanks. That's the first time I've heard the BP in this area. To bad they're encrypted but it is to be expected considering it's the BP.

CBP will be found on VS12 using $670
408.075 Long Island NY Been seeing this pop up and from the radios file, its the same rid's that FPS uses on 408.2000. Then ran to sdr#'s and see that the both transmit at the exact same time. I am close to the fed courthouse in Islip and 408.2000 comes in very strong. 408.075 still comes in with the rf turned all the way down so I don't think its an image. Anyone else see anything on 408.075? Nac is 270...

I'm getting something similar here with my Airspy Mini. I can receive 410.800 on 411.025 without fail... even my TRX-1 picks it up flawlessly. From what I can tell it may have something to do with my proximity to the transmitting tower -- because it only happens on transmission that come from it.

Just an FYI don't presume there's only one NAC code per frequency... :wink:
