[FedCom] Seattle Area Fed Mystery

[~Bill]

Have you narrowed down your search by attempting to listen to the input ??
410 would use 419 (+9 mhz) for the inputs, if following the NTIA standard

I've only encountered this freq a few times, but the agencies were/are
FAA in PA
US Army Fort Caron in CO
VA in TN
FBoP in CA
But all were either Analog or P25, none DMR

Happy Hunting

Could use some help tracking down a mystery DMR site in the Seattle area.
It's a DMR repeater on 410.9 and the users are using BP encryption with RAS.
I'm pretty sure it's from the downtown Seattle area but it's not from the VA
Hospital.

They were using the 8xxx RIDs below but it appears like they have moved to
5xxx RIDs for some strange reason.  They have NEVER dropped encryption so
it's a well-secured channel.  The transmissions are brief and rarely go
beyond 10 secs.  It smells of building security.  Maintenance or other
services are pretty yakky.  The activity is pretty light but they seem to
start around 5AM and generally stop by 6PM with very few radio checks
in-between those hours.

Here's my monitoring data from it:
