[TenTec] O2 output level with PSK aux

[Merle Bone]

The PSK idle signal is a two tone signal:
----------------------------------------------------------------------------------------
The PSK idle signal is a strong of zeros.
If one examines the PSK31 idle signal, it can be shown that the constant 
phase change of 180 degrees and the cosine shaped envelope of the signal 
generates two tones that are at the PSK31 center frequency +/- 15.625Hz. 
These tones can be used to measure the IMD of a transmitter."
----------------------------------------------------------------------------------------
The peak and average levels of the signal are quite different.
