You can make one yourself with a bridge motor controller and some sort of Arduino. You can then program it using the KX3 Programmers Reference.
Or, you can check out the TuneMatic products from JT Communications. He's already done the work and it works with the KX3 standing along or with the KX3/KXPA100 combo for mobile applications. Tarheel Antennas also resells this controller. I'm sure there are others but I see Jim Trapani (JT Communications) in a booth at the hamfests.
