315 mHz is in a band used by the US military, where they are already
"tolerating" a fair amount of intrusion from garage door openers and similar
devices. I was privvy to some US Navy classified message traffic that
discussed the issue. (It was classified because it identified specific
frequencies and such are always classified.)

This fellow, "new to the field," as he self-indentifies, seems like a source
for interference more than learning. A bit risky.

It depends upon where he is. Outside of the US, the US military is a guest,
and has no authority to use those frequencies. Certainly no claim.

There was an international incident here in Israel a few years ago when
a foreign miltary ship with a new radar system parked off the coast of
Lebanon with a new radar system which used the downlink frequency for our
local DBS system.

Within a week, the radar system was shut off, and they ship left.

So just because a military uses a frequency in their home country does not
mean that anyone elsewhere can not use it if it is legal, nor can that
military tell them to stop.
