Hi Ron;
The computer we were running RTTY on (the one we were experiencing the trouble
on; same computer) was a laptop...no keyboard cord....but there was a mouse
cord, power cord, ethernet cable etc.. It is a P166MMX with 32 meg ram...
Thanks for the info tho....
After making sure the bandpass filter was clear of all cables and making sure
the RTTY transmitter was on the beam antenna (that was NOT directly over the
building) the trouble seemed to go away.
