The definition used by OFCOM, the UK licensing authority, contains the
same words: "The average power ... in one RF cycle at the crest of the
modulation envelope" - but it also contains two useful loopholes.

The full wording is: "The average power supplied to the antenna by a
transmitter during one RF cycle at the crest of the modulation envelope
taken under normal operating conditions."

That means UK amateurs are explicitly permitted to allow for feedline
loss (very handy at UHF and higher) and abnormal transients aren't
counted. Given our 400W PEP output limit, we need all the concessions we
can get.

Okay, gentlemen, I can see where you're coming from now.
Incidentally, the (UK) definition above could be construed to allow
for some really serious QRO if one takes "normal operating conditions"
to refer to *atmospheric* conditions rather than those of the station
set-up. When's the next sunspot minima? :-}
