And if that is the case there are a lot of amps being sold that either
don't make sense, or are using false advertising.
Do 4 811As running 800 watts make sense? How about 8877s with anemic
power supplies that will hit 1500 pep in casual conversation, but won't
last through a contest? How about a pair of 3-500s running 1500 watts
from an amp you can carry under one arm? It'll run the legal limit, but
not for long on digital or contesting. The 8877 and 3-500 examples are
legal limit amps, but they won't do it all modes key down or even SSB in
contesting.
So I stick with the above statement. If you want it to hold up
contesting, or any other mode using a high duty cycle then it needs to
be able to do almost twice that ICAS.
