Subject: FCC Radio Service codes


I just purchased a county scanner frequency list through the

http://www.nat-com.com/

web site. It's definitely worth the five bucks, but it contains a column of
two-letter abbreviations (AM, PP, PL, PO, AF, etc.) that I'm not familiar
with and that I strongly suspect are the FCC's radio service codes. Does
anybody know where I can find an easily-accessible list of all of these
codes with their explanations? Thanks.
