I just ran a test on my O2 with a spectrum analyzer, and although I didn't
have the perfect test conditions, I noted that the CW trace at 100% and 50%
power level setting was the same as the SSB peak trace at both of those
levels within the nearest resolution, which was .2 dB. I used speech, not a
tone in the test. The tests were don with the speech processor on and off,
and I could see that with it on, the peaks were reached more consistently.
