Hi Bret;
That could be because the ratio of 25 watts to 100 watts is 4, an increase
of 6 dB, while the ratio of 300 to 500 is 1.7, an in
ubes plate modulated will do 700 watts

Again, It would be an S1 signal above a s9/30db level noise - a barely
perceivable difference. You would have to go from 100 to ~ 6,400 wa
I have found that a good rule of thumb for using linear
amplifiers on AM without burning up the tubes is the max. carrier
output from the linear should be no more than half the total CCS
dissipaton of the tubes. Case in point the pair of 6146's at
20-25W carrier, etc.

No matter what the spin, 100 to 400 watts is only 1 s-unit
and barely perceptible at the receiver.
A 30db/s9 signal is from a good antenna not from
100 or 400 watts.

It probably was Bill's voice and audio that drove the QRM away.

I've always found more RF power, at least in significant iterations of
~100watts, can make a big difference on the air in cutting thru noise
and band conditions. But what's more important is full modulation.
One potential benefit of running a -modified- Viking or Ranger, etc.
into an amp like
le unless you look at the meter.
Could be helpful during the winter months as a supplemental room heater.
