[Icom] AH-3 and IC 735

[Ken - VE5KC]

ICOM made an AH-2 tuner for use with the IC-735 which came with
a separate little box with the tune switch and interfacing cables that
mounts on the side of the IC-735.

When it comes to using with AH-3 and AH-4 tuners, the IC-735 
does not have necessary circuits and connections required.
