That's the default requirement: cable operators *are* required to put
EAS alerts on all channels. However, this requirement applies only to
EAS alerts applicable to the geographic area in which the cable system
is located. For EAS purposes, these areas are typically defined as
1/9th of a county, resulting in a 3x3 grid.
If a station and a cable system are in the same geographic area (such as
Philadelphia, from whence this thread originated), station licensees and
cable companies can enter into private agreements under which the cable
company will omit the EAS for that station. Cable companies are not
required to enter into such agreements, although they often do so if
their equipment can provide the option.
In geographic areas outside of a station's immediate area, such
agreements obviously don't make sense. No station could possibly devote
airtime to every EAS alert in its DMA.
In your case, Blacksburg is in Montgomery County, which is in the
Danville/Roanoke/Lynchburg DMA, so I assume your cable company gets
local stations from Roanoke and Lynchburg. You're definitely not in the
same EAS area (or even the same county) as either Roanoke or Lynchburg.
But Cox in Roanoke might have agreements with the Roanoke stations.
