Hi Gary
Even easier - I use a regular RCA patch cable (came with my keyer
anyway) and a Radio Shack RCA to 1/8" stereo adapter (don't have RS #)
with my CMOS-4. The adapter takes RCA center conductor to both tip and
ring. Works with my KX1 and FT-897. Handy, and, with no cutting and
soldering to one of those nasty 1/8" stereo plugs which always seem to
be chrome-plated and tough to solder, probably more reliable too!
