no. The hat trick is tuning up. One must tune up the linear amp. at 4x
the carrier P.- or 140w in this instance. With most ssb amps, it is best
to tune up with pulses (50wpm dits or a tuning pulser) to avoid
overloading the hv supply. // Setting the mic. gain is not as
straightforward as with ssb since the anode/plate meter is steady and
does not indicate modulation level. A pep wattmeter is more useful.
More mic. gain is not mo' betta. .

For maintaining a reasonable S/N ratio at the receiving end, AM consumes
more electricity and generates more heat than does SSB.
- Another disadvantage of AM is that operators tend to make moderately
boring, ten minute lock-to-talk soliloquies instead of engaging in
ordinary conversation. When I operate AM, I operate high speed VOX --
which drives AMers up the wall.
