In the USA, US Military has priority over all users on the 420-450 MHz band. Amateur Operators are secondary (cannot cause harmful interference to US Military. Under the terms of Part 15 all users under Part 15 must accept harmful interferences and must no cause harmful interference to other users.
BTW: ISM refers to services that do not intentionally radiate and do not use radiation for communication purposes. A Microwave is ISM. A WiFi is not. Art, KC6UQH

On UHF the band is shared up to a point the "other side" is considering us as "interference" at least in 2005... Just check slide 9 in the power point below. Can we also found them as QRM i think not as we are on a secondary basis :(
