Things are disappearing fast from this website, so get what you can before it is *all* gone.
[url='http://www.faa.gov/about/office_org/headquarters_offices/ato/atow/atc/library/view/documents/Web_AAM_2_2007.zip]6050_32B.pdf[/url] is extremely informative. I have seen some threads today about how far an ATC signal can be heard, there are charts in this .pdf showing listening distances based on how high the antenna is, etc. Of course, these distances are for something airborne .. but you get the picture.
Someone needs to download, and parse the Download Airspace Analysis Model Data Files zip file for us and then repost it. It contains a file named gmfall.dat that is a flat text file linking lat/longs to frequencies. This way we can plot them in a mapping software like Delorme or even the database here at radioreference.com. I would do it, but I just do not have the time.
I somewhat reget posting this information, since more than likely it will disappear faster, but it is currently in public domain and it seem better to share it now than for it to disappear altogether.
enjoy.
