K4JRG's Rotor Control DXA
This is K4JRG's
Rotor Control DXA.
A computer interface for the Yaesu DXA rotators

Rotor Control is our project to interface the Yaesu DXA series rotors to a PC serial port. The device employs a subset of the standard Yaesu GS-232 protocol so it can be used with off-the-shelf logging and rotor control software.

There's also a menu driven interface that can control the rotor by using a simple terminal emulator like Hyperterminal, included with Windows versions.

This product is proudly made in USA.


The philosophy behind a yet-another-rotor-control is to make an affordable and easy to use package.

The price was set based on material and assembly time costs, shipping/handling plus a very small profit as an incentive to produce it. The R&D investment and the many hours of software development is our donation to the Amateur Radio community.

The entire package, including worldwide shipping and handling is $75.
