I’d like to see some numerical analysis that it’s possible for a legal Part 15 FM signal to travel a mile under ANY conditions.
200 meters and maybe a bit more? Possible, under the conditions I described previously. Most likely, with the typical radio, a few hundred feet.
From what I understand, that whitespace document is just a proposal, and is not yet law. Plus, it’s unclear whether Part 15 broadcasting would be considered a legal use. Just because 87.9 is clear doesn’t mean you can legally use it, at least right now.
