I have modifed two rigs (IC-735 and IC-737A) to overcome the problem and I
would hope that all manufacturers would adapt this proceedure.
I added a phono connecter to the rear panel that was wired to the
output of the internal keyer. The computer (or a straight key) is
connected to the phono connector and the quarter-inch connector is used
only for the paddle.
I think that this circuit would be less expensive to manufacture.
The added phono connector would be less expensive in material AND labor
than the eliminated change-over switch.
