Leesburg was chosen as a location to test a new remote tower system.http://www.leesburgva.gov/government/de ... ower-faq-shttp://baltimore.cbslocal.com/2015/10/2 ... ort-tower/
It's been used for watching only, until now it seems.
Today is the first time I've noticed the CTAF/unicom frequency being used by a tower controller.
Nice find! This airport is covered by LiveATC as well, so this should provide some interesting listening.
