[Scan-DC] More Encrypted P25 -462.3, 467.3, 452.5875

[Travis]

Yesterday while in Chantilly I found 462.3 with 467.3 as an apparent input.
>From the same location I heard 452.875 encrypted and later in the area of
Rt28 and Rt 606 I heard voice on it, but I think that was likely Budget
Rent-a-Car at Dulles.

The other P25 encrypted freqs from before are:  452.425, 452.525, and
452.625.

Today from Leesburg I'm hearing 452.425 and 462.3, both very active.
