Postal Inspectors 409.9375

[upndn]

Hi all,While scanning the fed bands yesterday i came across what appears to be postal inspectors in Boston on 409.9375 It seemed like the base was encripted but the mobils were in the clear p25.The transmissions sounded like this:72 to Boston bravo 5.This must be a wide area system as i am in central suffolk county NY using the back of set antenna on a 996XT the signal was full scale.Any thoughts? Max.

Hi twobeermax,

I live about 10 miles from Boston, I'll spin the dial over that way when I get home from work. I also have some contacts in the postal dept. I'll see if I can turn up any info.

Thanks Bill, i figured that the answer to my question would come from you.One other question,is that a nationwide frequency?

 

[Wilrobnson]

Yes, all of New England USPS is $482

Just checking. That's the "black" channel. I'm guessing different regions utilize different color-named channels.

 

[ecps92]

$482 is a good guide that it's USPS.

As for Nationwide - Could be, altho I only have notes for this in
New England, NY/NJ/PA and WI

[ecps92]

I've never heard them refer to it back Color and/or Channel name, since they moved to P25

I thought there was a USPS Wiki , but it seems Not.

Maybe someone might create one this week

Monitoring Times had a list of color named channels a year or two ago.

Yes, but I have never heard them use these Colors on the radio.

Me neither, but 95% of the Postal Inspectors traffic I run into is encrypted...

No, that is not a nationwide frequency. They use different frequency pairs in different places. I would program all of them. A frequency that is used as a repeater in one city may be simplex/tac in another.

The 414.3625/CSQ frequency is programmed into the Morgan (Manhattan, NYC) operations and maintenance HTs as I/O (interop). 406.3375 (RED) is active in NYC. Sometimes 407.1375 (GREEN) pops up around Staten Island as well.
