[WT-support] erratic CW sending with internet

[Mikael Larsmark]

This is not just the case. I've tried keying using my main computer 
which is a dual core 2.2 GHz with 2GB of RAM and the CW sounded bad on 
that one while the old 1.8 GHz with 1GB ram at the contest station 
sounds great. It just stutters a bit when I ALT + TAB too much with 
heavy applications going (like firefox etc).

So I can't really define what the real problem is, if it's Windows 
hardware interfacing towards some hardware which messes things up or if 
it is just software. I've never seen this problem with Writelog or N1MM 
though...

Anyway, I think that Winkey is probably the way to go to make sure one 
gets rid of this problem but according to some the WT implementation of 
the WK chip isn't perfect.

CU lads in 9A CW this weekend!

I think it depends mainly on CPU load in compilance with network log sync traffic, system access method to LPT port (different in W98 and NT systems like W2k,WinXP), LPT BIOS settings (alowed DMA or strict IRQ) etc.
