well, it takes a while to replace trunked radio systems....I think everything west of Kenner on the La. State system is gone.
Putting up temp cell towers is a lot quicker....that is what I heard on the SATERN net this afternoon...(Salvation Army)
There is also supposed to be 270 hams on the air soon.....mostly shadowing the Red Cross shelters/locations (240 of them) so you are going to have more information flow....
There was ONE ham in New Orleans today on the air....on battery power....
