now this is a pretty basic circuit so I don't know how I could screw
it up, but it won't keythe rig. I am using the optoisolator circuit
on ae0y's page on lpt2. I show abt 4 volts between pins 4 and 5.
during keying resistance drops to 0. But rig won't key (ic-740 with
electronic keyer (turned off)).
HELP!! I thought about pulling the diode to raise the bias a bit,
would that work?
