The top dog on the East Coast, no question, is NASWA - who publish a hard copy bulletin every month, and when you subscribe and join the NASWA mailing list, you also get access to Dan K4VOA's superb spreadsheet that lists a ton of information on broadcasts using several different sources - all in one spreadsheet.
I would be remiss if I didn't mention my old friends at the Ontario DX Association - they've gone to electronic distribution, and have many very unique programs and resources. Based in Canada, of course, but don't let that stop you. They sell a CD of very technically oriented articles on a variety of subjects. For those that like to get to the nitty gritty of a subject, this is for you. It's pretty inexpensive, by the way.
