I wonder why EMSA doesn't simulcast their main dispatch channel on 463.100. I know that it would not only benefit scanner enthusiast, but also law enforcement officers that monitored it in their vehicles.
As far as news media having access to the digital radios, I don't know. From talking to an EMSA crew the other night they said that one of the media organizations was given restricted access to their digital radios after filing a freedom of information lawsuit.
