125.65 (a/c on UHF side?) - ANGEL 31 Direct Patuxant contact Center on 281.4
126.30 - NIGHTHAWK 10 - Self ID as single H-3
132.775 (a/c on UHF side?) - VAMPER XX (VAMPIRE?) [I missed the numbers] and
ZAPPER 11 both "switch to Norfolk on 126.05 or 370.925" [first VAMPER XX,
then shortly after ZAPPER 11] and of course it was UHF which I can't recieve
=(

Also I picked up a ?new? "Ground metering channel" for Dulles which was ID'd
as 124.075.
A/C would switch from that to Clearance Delivery on 135.7 then back to
124.075.
Anyone know what that's about?

Dulles Airport:

129.55 - Dulles Ramp
132.45 - Dulles Ground (WEST)
121.90 - Dulles Ground (EAST)

132.45 (GROUND) from this freq. a/c switch to tower on 128.425
121.90 (GROUND) from this freq a/c switch to tower on 120.1


I've also been trying to figure out the pattern of how the
frequencies/sectors are layed out. This is what I have so far..

125.65 goes into:
   124.55 - Potomac
   133.9 - Wash Center
   134.5 - Wash Center
   128.7 - Potomac

118.95 (Potomac) goes into:
   120.65 - Potomac

126.65 goes into:
   118.95 - Potomac
   123.825 - Potomac
   132.85 -

125.05 goes into:
   123.825 - Potomac
   125.65
   128.7 - Potomac

124.55 goes into:
   134.5 - Wash Center
   132.05 - Wash Center
   125.65

128.7 goes into:
   121.05 - Potomac
   124.2 -
   123.825 - Potomac
   124.55 - Potomac

120.45 goes into
   128.425 - Dulles tower

126.875 (Wash Center) goes into:
   121.025 - Wash Center

134.5 (Wash Center) goes into:
   132.05 - Wash Center
   125.45 - Wash Center

119.85 (Potomac) goes into:
   119.1 - DCA Tower

132.05 (Wash Center) goes into:
   124.55 - Potomac
   121.025 - (Wash Center)

133.975 (Wash Center) goes into:
   120.65 - Potomac
   134.625 - Wash Center

132.775 (Wash Center) goes into:
   126.05/370.925 - Norfolk

134.7 (Potomac) goes into:
   124.65 - Potomac

I know there's a lot a missed.. these are just the ones I grabbed over the
past 2 days. 134.7 ID'd as Potomac Approach is a new one for me. There are
dupes in the list I know but once I compile a huge list of which frequency
hands of to another I want to make some sort of 3D flow chart so it's easier
for myself and others to understand location of aircraft when it gets handed
off etc..
Any comments?? Anything to add? Please post or email me.

Thanks!
