There is a channel don't know if its VHF or UHF, But I know they broadcast Federal alerts from DC on it, for instance Weather Closings/delays and the like fro federal agencies. And they do radio function checks with 98% of the federal agencies in DC...Running down a list of standby/ready so to speak...Does anybody out there ever heard this broadcast or have clue what frequency band it is on?

I will try theseMany Thanks, Agencies like PFPA, CP, PP, SCOTUS, USSS, FBI, DC Metro and countless others are called on this channel at certain times of the day as a status/readiness check, and also to broadcast severe weather warnings and closures.

173.7875 great idea, put it at the very top of the band where nobody's antennas will ever be tuned.

The States use vs the Federal use of NAWAS will vary.

NAWAS was originally the Hotline for the Big-One, however migrated [as did CD, EMA , FEMA etc] to an All-Hazards approach. What you hear [in-state] for Nawas is probably the Monthly [Checkerboard Test] Test which allows for a Fan-out via Phone, e-mail, Text and Radio notification.


Somehow I doubt that. NAWAS is for confidential communications during [nuclear] attacks and other disasters. Broadcasting it over a radio channel would defeat the purpose.

Was 173.7875 ever confirmed?

155.745 in eastern Nebraska might be a Emergency Alert System feed (EAS). IIRC, NAWAS (National Warning and Alert System) is the hardwire system that links 'alert points' - EAS is the system that reaches out to the public via National Weather Radio, TV, commercial radio, etc.

This is a Fed Govie Freq for the Feds only, No Stateys involved. I am sure it came to place AFTER 9/11.
All Federal Agencies in the DC area check in on it daily at a certain time.
If they check in daily it shouldn't be too hard to catch during one of the check-in's.

You can try one of these I have found in a federal agency radio programming. They are listed as "DC INTEROP";

DCIO1 159.15000
DCIO2 168.87500
DCIO2 N 173.75000
DCIO2 S 168.08750
DCIO2 W 166.78750

The first frequency is the DC MPD Simulcast from their trunked system.
