I might add Rick that what ever the voltage that you are running on the DC
of the RF circuit the modulator must be capable of more than twice that
amount peak to peak on the scope for 100 percent modulation.

If you can come close with an audio output transformer just put that and a
speaker on it.  You'll be able to hear your audio and see it on the scope as
well.

How does one test a modulator. I will soon have a modulator capable of 
around 100 watts of audio....
