Highway Advisory Radio Moving to 1680AM

The Virginia Department of Transportation is in the process of moving its Highway Advisory Radio signal in Hampton Roads from 610 AM to 1680, at the high end of the AM band.  Highway Advisory Radio is a network of low power (10 watt) stations with a synthesized voice that broadcasts highway traffic information.  I've come to rely on these stations when driving in some of the more congested parts of Hampton Roads.  The information comes directly from VDOT and is usually up to date.

I'm familiar with low power radio, having started my broadcast career at Longwood College's 10 watt (we preferred 10,000 milliwatt) WLCX.  Low power stations have limited range.  VDOT's signal is sometimes difficult to hear, especially at night, when the stations are often drowned out by other, stronger stations.  Jennifer Gwaltney, a public information officer for VDOT, tells me the move to 1680 AM should create a clearer signal. 

The move to 1680 AM should be completed by the end of April.
