I live in western Loudoun County. A few days ago, my scanners stopped receiving Loudoun County. I have since been informed by Loudoun County that they have turned off the 800mhz transmitter sites in the western part of the county in anticipation to switching over operations to 700mhz frequencies. Currently the FCC site is down so I can't check for recent frequencies licensed to the County. I am posting this in case anyone else in western Loudon is having trouble or is no longer hearing Loudoun County trunked system.
