Hi, im reading the book GoogleMaps app with Rails and ajax, in the
chapter 5, i need to download the FCC ASR Database
(http://wireless.fcc.gov/uls/data/complete/r_tower.zip) but the link is
broken.

Do you know where im donwload this file?

Google don't give me any valid location.-

PD. sorry my english.
Thanks

http://wireless.fcc.gov/uls/data/complete/r_tower.zip seems to work for me. Maybe blocked from your location?

I can access with a proxy, thanks.
