Not specific to WL, but I would guess this is not an uncommon configuration
here.
I have my keyer with paddles, a straight key and the computer serial port
hooked up to my TS-830. The computer interface and the keyer are set up for
grid block. All three connect through a 3-way audio cable (with adapters) to
the rig.
I have noticed at times when I'm sending cw, all of a sudden I get a
constant key down that stays there until I pull the key plug from the back
of the radio disconnecting all three keying sources. This seems to have
started ever since bringing the serial port online for CW. I don't think
it's RF related as I'm not seeing problems at any other time.
Question is - should I be providing some sort of isolation between the three
key inputs? Holding down the straight key effectively places a short on the
keyer and computer interface outputs. I didn't think this would be a problem
- but now my best guess is I need to look more closely at it.
