The OTT places the 817 in packet mode and keys it. It plugs into the
accessory socket and comes with a momentary switch that you use to place
it into tune mode. Out of the box you would have to hold the OTT switch
closed while the Z-11 tunes.

With the Z-11 compatibility kit you replace the firmware with version 1.4
and install a jack on the back of the Z11 and connect the attached wire to
the tune LED. This way when you hit the tune button on the Z-11 it keys
the OTT until the antenna is tuned.

I heartily recommend it. It really is sweet, and W4RT Electronics is very
much a pleasure to do business with.
