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...

On SSB carrier will be controlled by modulation, naturally...

However, "swing kits" and cheap amps which count on "swing" are nothing
but junk... a junk amp cannot pump our 100 Watts continuous (however,
even in amateur operation amps are usually rated at 50% duty
cycle--basically means 1 min key down, one minute off--on the avg--or
50% on time during conversations)

"Backwards modulation" can be caused by over 100% modulation which
causes signal to be "stolen" from rf amplification and given to more
audio, or a linear NOT peaked correctly...

There are a LOT of junk amps out there and those purchasing/using them
just are not aware of what a real amp is...

And of course, if you buy a 500 watt amp and cut down drive from the
transmitter so that the linear is only putting out 250 watts it will run
much cooler--possibly even able to run a 100% duty cycle... and a
"swing kit" that is bouncing the signal up and down with am audio is
just a junk toy... I guess the "good ole buddies" just like to see a
meter swing on am... hey, whatever keeps a child entertained...

Warmest regards,

It just amazes me how amp users push the limits out of a amp. If the
outputs can do 200 watts at RF out compression, they will drive it to
do 200 watts dead key and modulate it with AM the P-P watt out is 200
watts with downward modulation.. They don't seem to realize that if
they drove it to 35-50 watts out and then apply modulation their
signal would be just as strong, hitting 200 watts P-P Out and the
current draw would be less, also much less heat and sound better. Oh
**** I said sound better, that is not the way in CB, the more they can
F
* up a radio, cutting limiters, adding a mic that overdrives the radio
into distortion, and using class C amps the more they like it.

Actually the difference from 35 watts to 100 watts is far less than
that from 5 to 35 watts. In fact the difference from 35 watts to 100
watts is really just discernable. To make a real noticable
difference
the power level has to go up by four times. Five to 35 is seven
times.

A 2x455 amp will work great. They are called 225's now, because
that's
how watts of DC input they use. It's a marketing ploy. Each MRF455 is
good for 60 watts max times a push/pull pair is 120 watts max RMS.
Expect OK audio on AM at 30 to 35 watts of dead key with a properly
biased box. Stay away from Class C (competition box or modulator)
units.
