They do that all the time. Whether it be a storm warning or a missing child report and test of the emergency broadcast system. Sometimes I get so sick of it I just have to unplug may cable and hook up my antenae and DTV converter and just watch regular tv. Atleast you won’t get those warnings then. Its irritating when it happens when your watching a show or a football game on the weekend.
yes ,,, I am know what the EAS does .... but it has never froze on CSPAN at the start of a political circus ... and then locked there for 15 minutes .... this was ABUSE of the EAS system by comcast.
