[Scan-DC] ARINC updates

[Mike Agner]

   I've been scanning the ARINC freqs listed on the Maryland Airports page, 
in the hopes of finding new stuff; and sure, enough the list for BWI has 
changed quite a bit in the 6 or 7 years since myself, Tony Orr, Flo Baines 
and others tracked in this band.

   I'm wondering if we still have some aero experts out there who can scan 
thru that list and tell me what callsigns are dead and buried.  I suspect 
TWA/Waterski is gone (filed chapter 11, I believe), as is Lockheed Martin, 
but what else?

   Also who is it that's on 130.475 that uses 131.325 as their maitenance freq?
