I used V-Soft's signal strength database to ID the strongest stations. This helps when not all stations are in Chicago.
For medium and low strength stations, I used the FCC database for various queries:
for all stations within 100km of me, for instance, click here.
You can get radio coverage maps from the FCC, or more refined maps from Radio Locator that show how likely it is to pick up the station.
Antenna is the orientation of the dipole; so the note "east/west" means the wire is strung east/west and sensitive to signals coming from the north or south.
Station IDs were either heard, inferred from strength, music type, from the list of Chicago stations, or best guess from distant station lists.

Since formatting is horrible, here is the Excel spreadsheet.
If a frequency is not listed, it was a channel subject to bad interference from a neighboring station.
The idea of finding the clear channels is to find one suitable for meteor scatter work: a normally too-distant station (because it is over the horizon) can suddenly boom in because the signal is reflected from a ionized meteor trail halfway between the listener and broadcaster.
Some interesting results: WXXC and WBYR, located in Marion and Fort Wayne, IN, at 150 miles away.

Nice bandscan. I could probably fill in the unsure spots for you, like 93.7 (WBCT for sure, if you're doing the scan in the city) and some others. I'm curious what your level of interest is in radio and what you know of the WTFDA. :) I like bandscans haha. I was just in Chicago last night and was checking on RDS info and if my list needed updates.
Thanks, I agree it is likely WBCT (300,000W vs. 12,000W) at nearly the same distance.
I like radio stuff but have never gotten into any of the specialized organizations.
Is RDS popular at all in Chicago? I know it's not as popular in the USA compared to Europe.
