Is anyone *controlling* his Icom R10 with an Icom OP-478 cable or RT
Systems CT29A cable -- as opposed to programming the memory, which I
know can be done?

It has been suggested that by putting a stereo to mono adapter on the
stereo phone plug of the cable and plugging into the CI-V side jack of
the radio that CAT control is possible without the $100 Icom CT-17
level converter. I am looking for confirmation before shelling out
for this receiver.
