[TenTec] New software

[Rsoifer at aol.com]

I see that T-T has posted a comment about the NR.  My own experience,  that 
using a high setting of NR (9) and an AGC slope of 1:10 reduces the popping 
 and distortion, is in line with their comment.  However, it still seems to 
 me that the new NR needs some more "fine tuning."  
 
I've set the sidetone level to 30 and it sounds pretty good with my 400 Hz  
tone.

There are a number of things I like about 2.043B -- one seems  to be
that the CAT interface seems a tab more robust.  I might just  be
dreaming it, but I've written a number of programs for my Orion  II
that use the CAT interface and one problem has always been that
if  one is sending a long sequence of commands that don't generate
responses to  the Orion, some of the commands are not executed
by the Orion.   Increasing the delay between commands helps, the
the delays required seem  to vary in not so predictable ways.
That problem SEEMS to be better than  with 2.039d.

BUT -- I really really dislike to new NR algorithm --  particularly
as it affects the side-tone, even with the NR off.  After  a couple
days of operating with 2.043B, I finally had enough and  went
back to 2.039d.  It seems to me the new NR algorithm is doing  things
even when NR is off...  I hope the next release either reverts  to
the old NR algorithm or gives the user a choice of which one he  wants.
In any case, the side-tone is atrocious unless kept at very low  levels
and/or NR is invoked at fairly high levels.  For those of us  in
very quiet locations, that drives me nuts.
