The loss of audio between 200hz and 100hz when in cw mode is problematic for 
me,  even though I have seen some posts that indicate it is not big deal for 

I commonly narrow down the cw filters to 100hz which eliminates a lot of noise, 
 especially Qrn type noise.  I am further disappointed that Ten Tec has come to 
the conclusion that this behaviour is an acceptable trait of the DSP filter as 
explained in their faq notes.  This indicates to me that they have tried to fix 
this problem,  but have been unable to and need to offer a plausable 
explanation as to why it is happening. 

I don't buy that!   This loss of audio was never an issue in the 1.xxx 
versions.  You can turn down the BW to 100hz and have the same audio strength 
that you had at 200Hz.  IF the loss of audio is inherent then why does it not 
happen in 1.xxx versions.   

I believe this needs looking into further and not just glossed over with a 
sentence or two explaining it away.  If anyone has additional information which 
could shed some light on this subject I would like to see it.
