While others have pointed out that the FCC was going after these twits because they didn't even have the proper power output level set for their license... The question for Amateurs is a good one though -- lots of people run lots of power and don't ever do even a cursory bit of math on their particular station (let alone their repeaters) to see if they're in any danger. These links may or may not be useful -- the information on them is dated 1997 and 1998 and they haven't apparently been updated since then. (Odd. It says the ARRL put in requests to make changes and expected to hear back in 1998. Ha!) http://n5xu.ece.utexas.edu/rfsafety/exemptions.shtml http://www.arrl.org/news/rfsafety/ The Handbook does have this all in a convenient to read format that covers the theory and "new" standards back in 1996/97(?), and it's also published online as a web page: http://www.arrl.org/news/rfsafety/hbkrf.html Nate WY0X
