Which helps *radio* how, again?  audio-only medium.

Not a fault of the EAS system, per se.  Interconnect issue - which CAP 
doesn't directly address.  In some cases, it could even be traced to 
improper installation of the equipment...  which would also be a 
possibility for any new CAP EAS equipment.  (and no GM will cut corners 
by trying to do it himself - or hire some high school kid to do it... 
believe that, and I've got some oceanfront property just outside Tucson 
you might be interested in...)

OK, I'll grant SAP as a possible benefit.

OK, but again - the existing EAS system works quite well when the 
originator(s) and stations let it; providing extra paths does nothing 
for *radio*, per se.

TV is not *radio.  *Another* does nothing feature, *as far as radio is 
concerned.

Which could still be implemented in an upgraded EAS; there are many 
features in EAS that have never been implemented.

And CAP isn't?  Anything that depends on the internet - or any other 
system, true - is vulnerable to everything from EMP to backhoe fades.  
The sole operational advantage is the "multiple routes" feature - which 
could be (and has, in some locales) done with legacy EAS.

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.

Change for the sake of change... I see.
