         Well maybe not identical.  Bandwidth is
identical but SSB audio response is not flat
according to Spectrogram.  Also the audio
response for Main RX is slightly different
than for Sub RX.  Main seems to slope up
slightly and Sub slopes down slightly.  With
0 dB RX EQ, both should be perfectly flat.
You can also hear this in the character of
the noise when you switch between the two.
The same is true in CW mode also.  Maybe
EQ needs a little more tweaking.  I'm not
sure if this is a problem in V1 or not since
I've never really checked it before.
