[Central-Electronics] 100V AM troubles

[Bill]

Bob, have gotten in to mine yet (stacked up with Rx's)
As I recall it uses I,Q modulator.
 Voice is phase shifted by 90 degrees between paths and 
 one modulator would use a sine wave and the other a cosine wave.
 adding/subtracting the two modulated waveforms results in usb or lsb.

 - For AM how much carrier leakage is on both halves.
 - I am guessing here, but what does each half look like in AM prior
    to them being combined.

I'll pull the docs later tonight.

I have a 100V that is working perfectly except for AM where there is
only 
very little modulation. I know AM is generated by 'unbalancing' the 
balanced modulator but I'll be darned if I can find the problem. Has
anyone 
had this AM problem? Any troubleshooting suggestions?

73, Bob
