Radio signal maps

Instapundit linked to a Doc Searls entry about the new liberal talk radio network. The article includes an interesting digression about AM radio propagation and has links to radio-locator.com, a database of information about broadcast stations in the USA. Each entry includes the station's website and the URL of any streaming broadcast, transmitting power, number and location of towers, ownership information, and -- this is the cool part -- links to daytime and nighttime coverage maps. Here's the entry for 1170 KFAQ. Advanced search will allow you to find all the stations with a certain frequency, and will do a fuzzy search around a frequency. There's even a mobile edition for downloading info to your PDA.

The coverage maps only show propagation of the ground wave, so if you remember Billy Parker's ads for the 50th anniversary of KVOO (now KFAQ) and the reference to "38 states, Mexico, and Canada", you'll be disappointed.

AM radio. Maps. These are a few of my favorite things.
