[RTTY] Running multiple versions of MMTTY & 2Tone questions

[RLVZ at aol.com]

Hi Guys,
 
Until now, I have only decoded RTTY with either one version of  MMTTY or 
2Tone running at the same time.  I'm getting ready to run  MMTTY and 2Tone at 
the same time and have some questions:
 
1) Using N1MM Logger and MMTTY, I have a great deal of  problems getting 
any computer to decode RTTY quickly and not slowing  down during a contest.  
I'm not sure, but I believe the slow decode problem  is a result of updates 
done to N1MM Logger or MMTTY, or both.  I say  that because 2-3 years ago I 
didn't have as great a problem with delayed  decoding.  So my first question 
is: since I already have problems with  my computers slowing down during a 
contest with only one version of MMTTY  running, won't this problem increase 
if I run multiple copies of MMTTY or 2Tone  at the same time?  (note: I've 
tried 3 different Windows 7 computers and  only one of them will decode 
quickly most of the time without slowing down  as the contest goes on, and that's 
my office computer which I have to  borrow before a contest)
 
2) I'm using a K3 and the decode audio comes from the  Line Out on the rear 
of the K3.  If I want to split this audio and run it  to two different 
CPU's can I use a simple Y adapter with excellent results, or  would I get 
likely reduce noise or distortion if I used  a Distribution Amp instead of a Y 
adapter?
 
Thanks & 73,
