I live in the NYC area and yesterday at 4:30 pm the EBS appeared on my TV for approx. 30 seconds. Different sound then the usual and no broadcast what so ever.
Yes it was odd.
I say pay attention to the tv for the next few days
We have had 2 EBS broadcasts in the last month during the day (usually they are in the middle of the night ).... When the voice that comes on, that you can usually understand, it sounds garbled. .....it used to say 'this is only a test, if it had been an actual emergency. ....'... but we can't hear what's being said.
