[ICOM] IC-7000 AM Modulation Problem

[David J. Ring, Jr.]

Hi Larry,

I was reading your posts - and I have a couple of questions.  Forgive me if 
you've already answered them.

You mention that you modulated your AM signal with a tone, and it modulated 
100%.

But with voice only 30%.

That is really puzzling!

Have you tried feeding an audio amplifier (at microphone level plus 15 dB) 
into the microphone connection?  Or perhaps going into the rear AUX "din" 
connector (I don't have that model, but other recent ICOM's have this.).

I'd make a tape recording with my voice hitting 0 VU and then with a tone 
hitting 0 VU and feed it into the microphone connector - then the AUX 
connector.  Of course the modulation "should" peak the same - unless the 
TONE control is set differently to favor one or the other.

This is too strange!
