Ah, thanks. However, over here we do have "legal" intrusions into some of
the amateur bands, most are in the microwave region, notably 10GHz, where
we lost a sizeable chunk a while back.

The main one though is 431-432 MHz which is not available for use within
100km of Charing Cross (central London) and also for some distance around
the military radar installation at Fylingdales in Yorkshire. In the London
area I believe it's allocated to taxis of all things..! There isn't a lot
of amateur activity in that segment, I think some wide-split repeaters may
have inputs or outputs there but generally it's a low-occupancy segment of
the band, so all in all it's not a major hassle.

It's the principle of the thing that annoys me, though. Even where we are
primary users, such as 2m, we can claim *no* protection from interference,
even if the cause of said interference shouldn't be there.
