i dont monitor federal due to the fact that i am just in the process of ordering my first digital radio, and from what i hear im not sure how interesting it is due to the fact that much of it(atleast a good portion) is encrypted. But, for those of u who are avid listeners to it, what are some of ur fav. organizations to listen in on, and since im in the philly metro area of PA, what is pretty neat to listen to around here?...maybe i can get into it. what gets discussed on FBI freqs. and US marshall channels?....as well as others.
