The most important single accessory item to have
in your AM shack is a
way to monitor modulation - a cheap o'scope is a
good choice. Keep an
eye on it to ensure you have reasonably strong
average modulation
levels, and negative peaks that don't go all the
way to 100% and pinch
off the carrier.
You current quest for a good mic is already
underway. The next item I
would want is a compressor-limiter. This device
allows you to wander a
bit from the microphone, or get excited speaking
loudly, without under
or overmodulating. You can get a "microphone
processor" which combines
a mic preamp with equalizer, compressor, limiter,
de-esser, and such.
I'm fond of the Berhinger ULTRAVOICE VX2000 for
that job. They go for
maybe $70 on eBay.
I sometimes run more elaborate AM broadcast
processors on my rigs,
too... but that's because I'm a nut. The Berhinger
ULTRAVOICE VX2000
alone does a great job for ham AM work.
On the other hand, on my Apache I use a plain D104
driving the musical
instrument (High-Z) input of a DBX 163X
compressor-limiter - sounds
great and very simple. They usually go for $80 on
eBay
