Just up out of the noise works well for me, with a SignaLink USB 
soundcard/interface box

Someone else will have to answer this one... don't have an opentracker.

Comparing an AEA PK232 to the SignaLink USB, I would say no. I have used 
both units as mobile and fixed with a Vista based laptop (Intel dual 
core processor) just to test the systems out. The SignaLink seems to 
work marginally better mobile, probably because the TNC is bothered more 
by engine noise.
