Another CloseCall hit today from the White Tanks site is 452.1250, PL 131.8. Traffic sounded like trucks of some sort.
Again, nothing in the database or FCC files on it...
Argh! I searched with AZ as the state, I forgot that that only lists LICENSEES in Arizona, not transmitter sites. (This licensee is in CA...)
Odd though that it was acting as a conventional repeater with PL though.
