RT-21 GH Map   Version 2.0.2 adds embedded Java (see Release Notes)

A simple and basic graphical RT-21 control program intended for mouse or touchscreen operation by dragging the desired beam pattern to a desired heading.  This program supports up to three rotators on one graphical display.  We provide a default compass rose background but you can utilize any graphical background you wish.  Background Azimuth projection maps centered on your QTH are readily available on the web and can be simply selected for use as your background image.

RT-21 Console Firmware

RT-21 Console is a download firmware load for any RT-21 that converts that unit into a control console for another RT-21 controller.  Essentially, the RT-21 Console implements a “computer terminal” in an RT-21 unit that sends and receives RT-21 commands over an RS-232 link.  Both the rotor connected RT-21, and the RT-21 Console can control the attached rotator, and view headings.

RT-20 Last Production Versions (OLD)

Old RT-20 firmware….in RT-20, there are different loads for AC motors than for DC motors.

The 2.02 is the AC motor version  (Hy-Gain, create etc.)
The 1.05 is the DC motor version  (Orion, SPID etc)
TIC Rings, K0XG, and Prop Pitch versions are all separate and the files are included.

The ending ‘a’ denotes a PCB version of 1.8 or later.  Earlier boards used the firmware NOT ending in ‘a’

The included loader must be used….after starting the load, you must cycle power quite quickly….< 1/4 second off time.

Call us if you need help…but we would recommend that it’s better to spend the $25 for an RT-21 CPU upgrade instead.
