[Kenwood] TS930 SSB Umph

[Dr. Gerald N. Johnson, electrical engineer]

You can drive the p out of the finals, but the extra output will only be
distortion products, mostly splatter. You might increase the signal 1 o3
2 dB, much less than an S-unit, of no consequence at the other end of
any path not absolutely at the noise threshold.

50 to 60 watts is too much on an averaging wattmeter, you are already
driving the p out of the finals and splattering.

Remember that the PA and driver transistors for the 930 are expensive
and hard to find. Overdriving them can be shortening their life (and
that of the internal power supply and when the power supply fails and
feeds extra voltage to the PA stages their lives get really short).

If you want a bigger signal, you need a bigger antenna or an external
amplifier. TINFL.
