Hi there I'm puting together a repeater package for our local ham group and run into a bit of a snag the IC-F121 radios external COS signal is active low but only floats around 0.9 volts the controller I've got to work with is a Crayfield CD-3P controller and it doesn't reconize the signal since the swing is so small. The easy solution is to use a relay to invert the signal, but I'm not sure what voltage/ Amperage the horn line on the radio will handle. Is there any one who can help?
