[TenTec] Would like Corsair II comments

[N1EU]

I think Carl and Steve are both correct.  The
audio-derived AGC scheme seems to have continued from
the Triton to the Omni and finally to the Corsair. 
Depending on the rig, there was an audio notch filter
and/or audio bandpass filter within the agc loop.  

IMHO, this AGC scheme should have been retired before
the introduction of the Corsair and an i.f. agc scheme
used.  It wasn't until the Omni V that this finally
occurred.
