Hello. I am doing some scanning in East Lansing, MI, and have come across a frequency: 851.475 to 851.4875 MHz. It is not always 100% duty cycle, and sounds like some sort of digital audio format, but not one that is familiar to me. It is a strong signal like a repeater output. Additionally...

This evening, I've been receiving NXDN traffic on 453.175. The only license near me using that frequency is Manchester Fire Department. I've been unable to confirm that it IS Manchester FD for sure, but I have determined it's using a RAN of 3. Anyone else in range noticing this? Will update...

Hello - I have been detecting a continuous signal at exactly 462.000 MHz. While initially I thought this was GMRS, the GMRS channel plan starts at 462.5625 MHz, and does not appear to include 462 on the nose. I am able to pull DCS codes from the signal, however, they are non-standard codes...

Monitored from the Georgetown, KY area via SDR# & DSD+. I have searched this frequency in the ULS database for the states of Kentucky, Ohio, Indiana, & Tennessee, and nothing comes back. See System Details Below Network: 1 Region: 1 Site: 3 Color Code: 0 Active Control Channel: 454.4750

I've been learning to use my RTL SDR and have come across a signal I can't identify: FREQ: 418.0250 - 418.035 MHz (the frequency jumps around from day to day MODE: DSB MY QTH: San Fernando Valley,Los Angeles, CA TIME: Different times throughout the day. My times are pdt. Link to a video...

Hi guys, So I was playing with a rtl sdr dongle lately and came across a strange signal exactly at 120 mhz. I am using gqrx for sdr side. Any idea what it is? Here is the gps info of my location if relevant: Latitude:31.70677465 N Longitude:76.52492523 E Sea level: 882 M

Hello scanners! A while ago, I stumbled on a mysterious station from my location in Middlesex county. It is a sort of ambulance or public safety station on 152.370 MHz, and uses a DCS code of 155. I have been looking for this station's information, but it is not on RadioReference, apparently...

I am picking up a Motorolla CC on 859.437500 very clearly while near the intersection of US1 and HWY64 in Cary. The SID is 2C10 (which is what the VIPER trailer system uses) and I am hearing some occasional talk (slightly informal) on tg #4656 (a tg on the viper system). They keep mentioning...

In the spirit of the http://forums.radioreference.com/illinois-radio-discussion-forum/95373-what-info-you-trying-identify-champaign-urbana.html I am making a similar page for Bloomington-Normal. Trying to identify frequencies/talkgroups can be a time consuming task, but with shared knowledge...

From 1830 (when I turned on the stream) until posting this, I have heard Berks giving security checks on P-1 to a "Unit 8-7-5-3" or "Unit A-7-5-3". Not Eighty-seven - Fifty-three, but Eight-Seven-Five-Three or A-Seven-Five-Three. Who is this? They were somewhere (not mentioned) awaiting...

I’m posting this to more than one list in order to get coverage in neighboring states. I’m in NE KS and we’ve had a band opening in the past couple of days that has produced several unknown systems between 162-174 MHz. Can anyone identify these and tell me where they’re located? I’ll be happy to...
