I wonder if you have a grounding problem. I run sstv using my omni6+
connected to my pc and no problems even with the amplifier on running 500
watts. I use home a home brew keying device connected to a serial port on
the pc with 1 transistor and 2 resistors to the key jack. Never had any
problems. I have used a cw keyboard and psk32 using the same stuff with no
problems even with the centurion driven near max output. You must have rf
floating in the shack somehow. i do not have any kind of rf blocking
devices on my cables either.
