Mount Vernon Licenses Additional Frequency

Mount Vernon has added another frequency onto their recent license. They are now licensed on 452.3875, 461.4625, and 462.1375. In my limited monitoring, I haven't heard anything on these new frequencies. I did hear security yesterday on their usual frequency of 464.5250 [ d073]. I expect that they will begin to migrate to these three new frequencies from their current frequencies of 464.4750, 464.5250, and 464.6750.
