If you have any diodes in a switch box or the like, be sure to add a
bypass cap across the diode - 0.01 uF will do. Diodes are great
harmonic generators (and mixers) and equipment connected to control
cables or feed lines often is pretty hot with RF current. That includes
rotator controllers, too.

If the radio is keying both the detuning relay and an amp, you want to use
some series diodes to prevent sneak paths between amp key voltage and your
detuning relay voltage. These isolation diodes do not add any delays.
