I just purchased a w9xt card and am going to use a com port for cw
keying, keeping the contest card on ltp one. In the ltp interface pin
18 is labeled key return, and is the "-" connection to the phono plug.
On the com port circuit, there is nothing labeled key return. What do
you use as the"-" for the phono plug.
