Jim:

I have never seen an amp rated both 100 watts am and 100 watts ssb. By
nature a ssb signal is only half the bandwidth (roughly) of an am
signal.

I have an old CMI linear I have ran since 1975--100 watts am but 165
watts ssb p-p. I have found most amps to fall relatively close to
ratings, if a 100 watt amp.

I have looked at the new amps and they components are truly pushed to
the max. I would think they must run HOT!!!

On an am signal, the power out should remain relatively the same with
and without audio. "Swing kits" cause the rf out to vary--but why,
unless you are driving components above their ratings and need to avg
the power out. A true 100 watt amp should hold a fairly steady 100 watt
output on AM from key down to key up.

Some freaks out there just like to see a meter "swing" like ssb
causes--so they either go a swing kit or a variable power xmitter which
allow rf increases on peak audio--in some ways it reminds me of a childs
toy.

There is no reason for a 100 Watt linear to NOT DO 100 watts dead key
am
with 100% modulation... same goes with all other amps or
greater/lesser
ratings.
.
Explain to me how you can do 100 watts

deadkey out of a 100 watt amp and get 400

watt peak-to-peak swing out of it?

Huh? He said 100 watts, not 400 and he didn't mention swing at all.


Jay is right about the power end of it. If an amp is not rated
anything
other than "100 watts", it would be smart to assume it is 100 watts
output
*maximum*. That means 100 watts on FM or CW or any digital mode, but
ssb
would be 100 watts pep as would AM. In the case of AM, that means a
25 watt
carrier (to end up with 100 watts pep).
