[EAS] Alerting options

[Mike McCarthy]

Illinois is there now on VHF-L 44 Mhz and has been since the start of 
EAS in 1997.  See my previous comment on this.  VHF-L still has 
challenges and would require a rather cumbersome telco network lest they 
go to satellite for distribution to those regional TX's. Never the less, 
these types of regionalized transmitters can be used for  region 
specific alerts if they can be accessed individually or in small clusters.

The only substantive change I would make is to require all stations 
monitor that IEMA channel directly for the RMT's and other state 
messages and get rid of the regional one step daisy chain for those 
messages leaving the PEP and one other station for OTA relaying.
