would they be searching for someone outside of the airport, say like a few miles away.

How about typing the Freq again

I read it as 172.9000, since 172.2900 would not be valid, but 172.2875 would be. Also a NAC would help

[ecps92]

172.2875

i think it is rounding up the frequency to 172.2900

 

[ecps92]

OK, then ignore the TSA suggestion

172.2875

i think it is rounding up the frequency to 172.2900

I have not logged it in the Philadelphia area, but all my previous encounters with 172.2875 MHz have been the FBI with a NAC of N167 in multiple areas...

unknown 172.2875

This frequency was discussed back in February, 2010:

Looks like 172.2875 $167 is related to the FBI based on a new tone observed, and a radio check heard on it based out of Newark. Maybe has multiple NAC's for different uses??

Also, I've noticed that the FBI Newark Base radio checks vary now by time, but mostly based around the :15 & :45 past the hour still.

Which is why folks are generally taught/helped with Do Not Post actival Surv info, however apparently you want to loose the entire opportunity to Grow the monitoring of Feds by asking for the thread to be deleted ? Not.

36 posts ?

Maybe a band openning from the Newark area

re:unknown 172.29

its a strong signal 10 miles north of trenton, nj, can pick it up with a 1 inch antenna. alot of talkaround usage, mostly referred to as charlie 1, sometimes F1. its been used from north philadelphia.

What you will find on Wide-Area Federal Systems is that they have multiple Repeater sites with a common input frequency. This allows them to cover larger Areas, as such from a scanner perspective, you might be listening to a NNJ Operations, but hearing it on the Central NJ Rptr (since they are linked)
