[Amps] Amplifier Vs Plate Modulated

[Paul Baldock]

I assure you that AM is alive and well.

You might also consider that most older amps (not all) when you are 
not speaking on SSB have 0% efficiency, and around 300W to 400W plate 
dissipation.

You may have noticed that on AM many operators talk and talk and 
talk. You probably thought they were just long winded. But no, they 
are just trying to keep the efficiency up.
