[ct-user] FT990 CW problem w/rig control

[AA4NC@aol.com (AA4NC@aol.com)]

Setup: Using Yaesu FT990 with CT and COM port rig control thru FIF232, CW sent 
from LPT port, Pentium 133

I'm having a problem with "distorted" CW characters (usually a dit becomes too 
long and sounds like a dash) if the character coincides with the CAT poll on 
the radio. It seems as though the computer can't poll the radio and send code 
at the same time. I don't remember having a problem like this before, and I 
have no problem with the same setup using an FT1000MP. I've eliminated RF as 
the problem, as it occurs at QRP level as well as QRO.

Any ideas much appreciated...
