Yes, I wasn't very clear. I did mean with modification. Many of the
aerial plans do allow for use at other frequencies.

At such low power I don't think there would be a problem. If the 'PA'
is going to go it'll go quickly. So much better in the valve days -
when they started to glow red you knew there was a problem and could
switch off - semiconductors go into thermal runaway and that's end of
story. I did hear of one chap who coverd a golf course with a rabbit
base station with an aerial attached.
