EAS now works, but has some big limits, things we could not do much about back in the 80's when the current system was set up. Now we can overcome those limitation. CAP added to EAS gives us the capability, among other things to;
1. More directly target areas
2. Include much more information in text form as well as audio than the current system can.
3. Provide cleaner feeds. ( who here hasn't gotten an alert that was almost unintelligible?)
4. Provide additional audio and text selectable by the end user for translation i.e. Spanish for those station in that format.
5. Permit additional paths for the information to get to the end user.
6. Provide Photos for TV for things like Amber alerts.
7. several other things that may not help everyone but may still help save lives in many cases.
Without CAP we have the 20+ years old system that is still, in many areas, a bucket brigade carrying short messages with the resultant loss in quality and accuracy that occurs with multiple relays. That chain is very vulnerable.
The same naysayers who bitched when we went to EAS from EBS can't see the advantages, largely because they don't understand all the system is capable of doing. Personally I'll be glad to replace the old stuff with equipment with the new improved capability. Carts worked, Turntables worked, wire recorders worked, reel to reel worked but we have evolved and the Emergency alerting systems need to evolve and grow with them.
