Posting a query to one of the scanner newsgroups might also bring some answers. Those who use these pages will often send me updates for their local areas, and I try to add that information to the pages as soon as possible. I leave it up to the local monitors from the areas covered here to help keep the pages for their own localities current. As far as complete updates go, this site covers too large an area for annual updates. I will update each state with the latest data available to me as I have the time.
Updates are always welcome.
Updates which don't include a county and state will usually be discarded since my site covers hundreds of counties in about ten states and I don't have the time to search for the correct page when making updates. Because of the scope of this site, I get many updates from those who visit it. I make the changes to the pages as I have the time. Depending upon how busy I am, it may take from a couple of weeks to a couple of months for me to get to changes that have been sent to me. Frequency usage in the U.S. is a matter of public record.
