Not sure it's been mentioned on the forums before, but the FCC's AM broadcast query now includes links showing a daytime groundwave contour map for each station in the database.

In such cases, only the transmitter site is shown on the nighttime map.
The program input information such as power and antenna height were obtained from the FCC database.

AM options include daytime groundwave coverage and nighttime primary and secondary skywave coverage. North Africa • The Colorado DTRS coverage maps were generated using a free program called Radio Mobile. Using an antenna with higher gain will give much better results.

County Overlay for Google Earth (KML), ASRS Queries I'm trying to get my hands on something that will do AM MW pattern plots....something cheaper than V-Soft....which is way beyond my pocket book.I'd like to be able to use the software to see if some AM stations could expand their signal, as other co-channel stations turn in their licenses.

During the daytime there is little to no skywave propagation, so skywave interference does not normally occur. At the FM Query or TV Query search form, enter your search parameters, and select the longer, detailed Query output. [CDATA[// >
