[Scan-DC] Re: 341.75

[Jeff]

Larry,
Any thoughts on why Langley switched?. Last night I searched the entire IFR
for any references to 341.75. Came up empty handed. I know used to be if I
did that for that freq several MIL bases around would pop up. Langley was
one of them that had this freq listed as to HQ TIMING freq. Now it doesn't
nor does anybody else. Struck me as odd hat everybody dropped it from the
IFR. LFI now lists another freq as HQ timing.
