[Peter Voelpel]

Peak envelope power is the average power supplied to the antenna
transmission line by a transmitter during one radio frequency cycle at the
crest of the modulation envelope, under normal operating conditions.

The crest of the envelope in that example is 400V.
Since 400V peak equal 282V effective, PEP power is 1600W not 3200W.

Lou  --  A question.  I measured 400v-pk into 49.9-ohms @ 7MHz with a  
SB-220.  How many PEP W is this?



The way I figure it, that is 3200 watts at that point in time
