163.1000?

[CDS-INC]

Does anyone know what this frequency is used for?

163.1000mhz

I hear it from time to time here in White plains and it just sounds like something that would be MURS Chatter,

163.100 is one of the federal "common" frequencies that all of the agencies have access to, think of it as mutual aid for the feds. At least, that is what I have always been told.

What's it used for? Just about anything.

Over the years, I've heard:
-US Marshals setting up a raid
-US Fish and Wildlife doing a capture/kill on a herd of wild Canadian geese
-NPS Snowplows chatting in the Olympic National Park
-REALLY bored FBI agents on a stakeout
-Forest Service fire handcrew members chatting
-DOE special materials convoys chatting
-USGS surveyors...surveying
-GSA building engineers using it when their repeater went kaput
...etc

Think of it as CB channel 19 of the US Gov't.

Its use is not just limited to the feds. Our state police use it as a general operations/tactical channel along with 168.350. I understand even some local municipalities have both freqs in their radios now.

Manytimes the CTCSS or DCS tone might help ID who it is.

It's pretty much a variety of Federal Agencies for Interface.

The NTIA Redbook released earlier this year indicates that 163.100 is supposed to be a repeater output with 168.350 being the input. I will take a few years for all the agencies to program their radios to comply with this direction and/or get the word about the change. Two narrow band frequencies have been designated as replacements and they are 168.6125 and 163.7125. These new frequencies are limited to mobile simplex use only. I'm keeping 163.100 and 168.350 in my scanners for a few years as I would imagine not every federal agency will get up to speed on the change or will ignore the direction for awhile because they just don't want to reprogram their radios.

Where can I get a copy of that NTIA redbook and what exactly does it contain ?

Google "NTIA redbook " and it will come up as a PDF Adobe file, and save it.
It contains the operations standards for goverment agency use and frequencies

Ayup, thassa big ten fer good buddy... YEE-HAAAAaaaaaa! How 'bout it skipland, gotta copy onna Marshall Dillon comin' atcha inna Federal Express motor carriage? (beep boop buzz blurp woop woop anna rama lama ding dong)

Well since AM is limited to 4 watts for us mere mortals, I have to assume they will be working SSB? :lol:
