[EAS] This weeks IPAWS RWT

[KALX Engineering]

Hmmm, 100%?  My EASyCAP B3030 is set to check for a valid digital signature and I did receive and log this week's RWT.  Is my unit not compliant?

>Um, well that should mean that 100% of *compliant EAS devices will not log the receipt.  Section 11.56 of the FCC's rules requires EAS Participants to "configure their systems to reject all CAP-formatted EAS messages that include an invalid digital signature."  In other words, 11.56(c) basically **requires EAS devices to check digital signatures.
