How is AMR dispatched in D.C.? I don't hear them on DCFD's P25 system. Thanks for any information you can provide!
D.C. AMR radio channels?

That license is only for ops at Nationals Park. AMR is almost certainly using this system:

This system has incredible range ... I'm hearing private ambulances being dispatched in DC at home here just south of BWI airport. At some point, there was activity on other talkgroups talking about the north side of Baltimore City. Between this activity and the fact that someone posted information with the RRDB listings saying they provide coverage in Baltimore, I seriously doubt that all of the site saying "DC area" in really in DC.... I did some look-ups of a couple of site frequencies and the ones I found each pointed to a transmitter site in Montgomery County - with an ERP of 1000.... other site frequencies listed on RRDB didn't appear to be listed on fcc.gov at all.... Kinda wondering where all of that information on RRDB came from......

pdv Wireless has a lot of geographic market area licenses.
These are for blocks of frequencies in a market area instead of individual frequencies at a specific site.
They have radio service code YD - SMR, 896-901/935-940 MHz, Auctioned.
You have to do a geosearch on the FCC ULS license search page to find them.
If you don't know how geosearch works, follow the instructions at Part 22 Paging Channels - The RadioReference Wiki.
Yes, "DC Area" probably means "Baltimore Area" for some of the sites. And I'm not sure where all the new info for this system is coming from. I hope someone isn't just taking it from licenses without verifying the frequencies via actual monitoring...

I was think that also -- particularly in light of the fact that I was recently told be a DBadmin that - even though I provided a list of information directly from a system owner, it was unacceptable unless and until I personally monitored it -- so it was rejected......

If you look at the database info for this system it includes LCN, color code and in some cases site neighbors. You can't get that from FCC licenses.
The site neighbors are only listed for sites I verified several weeks ago using DSD+ - neighbors aren't listed for the sites that were recently added. Color Code seems to be 0 across all sites, so that's easy. The LCNs may make sense, however. The frequencies listed don't just run from low to high, so maybe it is legitimate.

Still could be (and looks like) information provided from someone vs. "monitored" like I as told was required....

Given the signal strength, I'd say the site 051 33 is close to BWI Airport....

Has anyone had any success with monitoring AMR? At this time I am not getting any activity on any of the DC area sites
