Agree and disagree

For example, let's start with a 100-Watt exciter then add an afterburner

of
800 Watts. Doubling power is 3 dB and an S-unit is 6dB. So from 100W to

200W
is 3dB, 200W to 400W is 3 more dB, and 400W to 800W is 3 more dB for a

total
of 9 dB or only 1-1/2 S-Units possible increase on the receiving end. One
can achieve almost the same result with a 3-element beam.


Not many can put up a 3 element beam for 80 meters, 40 meters either. Even
a rotatable dipole is not an option for most on 80. The amplifier will sit
on the same desk as the rig in most cases.
Granted it will not do anything for my receive.

I don't use my amp very much. It did come in handy as I was talking to a
portable station last Sunday morning on 80 meters. He had a bunch of static
and qrm (Shelby hamfest was where he was at) and by me running an amp I
could get over the local noise he had.
