Not all are confirmed, but most are. There are a lot of them. Some are more active than others. There may be other frequencies, higher or lower, that no one's heard.
6200 and 8050 are used in the US by FEMA and the National Guard respectively. It is not known if their presence on the list is due to listener confusion.
9025 is also a busy US Air Force ALE frequency. Dialing instructions for phone patches are passed in the AMD field. Strange though it seems, Mexican activity has also been repeatedly confirmed here.
All kHz, USB unless noted.
