[RTTY] Help with keeping RF out of PC

[Peter Laws]

I had a little, um, "incident" a while back (T-day weekend) which caused 
me to have to replace the Athlon/Abit KT7A combo with a Duron/Soyo Dragon 
somethingorother.  Everything works, but now the MMTTY engine (under N1MM 
Logger) will stop decoding and lockup.

I sent the MMTTY error message to the MMTTY list but since it only seems 
to occur on transmit, the conclusion seems to be that RF is getting into 
the PC.

My thinking is that it's the soundcard itself, since 1) I can still 
transmit after MMTTY goes QRT (IC746PRO in FSK via RB+) and 2) when I 
re-init the digital interface window in N1MM Logger MMTTY sometimes can't 
open the soundcard (per the dialog that pops up).

It should be mentioned that I rerouted and generally tidied up cabling 
behind the desk in the radio room at the same time I was doing the 
rebuild, so it's entirely possible that this is part of my problem.

So, what I need is a primer on keeping RF out of the PC.  Pointers?  
Ideas?
