[RFI] Keying problem

[John Kjos]

Hi, I am using the printer port on my computer for CW keying during
contests. On 20 meters I am having some sort of problem. When I try and send
CW via the computer it locks the radio into transmit without sending
anything, just a carrier. As soon as I pull the cable out of the keying
jack, it stops. I am sure it is a RF problem somehow, as it only does it
with the amp in line running 1KW. 200 watts out of the radio it is fine. Any
suggestions on a remedy? Thanks- John W9RPM
