FT-100D question: Is ALC a good indication of modulation?
 

Hello all. I haven't been using my current FT-100D for very long so I am unsure
of how good it sounds on SSB. I have selected the "ALC" display, which, from
what I understand, is supposed to indicate modulation. The books says to adjust
the mic gain so that 3 or 4 bars are indicated in ALC when talking normally. I
can't seem to get 3 or 4 bars when talking normally. On SSB I can see the RF
output bar moving and peaking at times. I have the mic gain set at 40 with a
Heil HM-10 boom mic. Can anyone offer suggestions for adjusting my audio?

Dunno, I would use the method I described in a similar post the other
day.
Use an average meter, and talk and adjust until you get to a point
you see no visible increase on the wattmeter. A stock mike should be
at about the half way point of the mike gain. If you can go all the
way up, and still see increases, you may need a preamp. Not familiar
with the yeasu mike setups...My 706 needs one using my audio technica
mike, but fairly normal for the icoms. A heil needs a preamp to have
enough drive on the 706. Might need one on the ft-100, but I'm not
sure. Compare it with the stock mike, and see if you see a large
difference in mike drive. MK
