Hey, that's my site! Actually it is about 10 months behind (maybe more). I downloaded the FCC db files and was messing around one night and came up with that simple page. I plan on updating the database soon and hopefully doing a little more as far as search abilities go.
I also created this page for ham radio licenses:
http://www.arresthistory.com/haml.asp
That page allows a basic callsign look up BUT you can also enter just a city and state, a street name, a last name, a first name or any combination and find ham licensees. This database too is dated, maybe a year old.
I originally created them for myself just to toy around with and posted the link once before.
