This simple Ham Radio control (CAT) program is a highly generic presenting the user to the same graphical user interface regardless of which radio is being controlled.
Software supports the most commonly used CAT commands and integrates well with other ham radio programs. Works with practically all known (and unknown) amateur radios.
Features
GRig offers you a simple, fast and easy to use graphical interface to your radio. And it offers you the same user interface regardless of what kind of radio you are using. GRig will not try to mimic the look and feel of a particular radio front panel, instead it tries to offer you an ergonomical graphical user interface.
Don't let the simple user interface fool you. Beneath it there is robust and scalable architecture that has been designed for smooth, near-real-time user experience.
Below you can find a description of the most significant features of Grig.
Quick-Tune
Most applications will give you a tuning-knob on the screen as primary frequency control device. While a tuning knob is a great thing on the front panel of a radio, it is really useless in a software application. Just try to imagine sweeping the 15 meter band using a software tuning knob and a mouse as a primary control device.

Tuning with Grig is much easier! You simply click on the frequency digit you whish to change. Clicking with the left mouse button will increase the value by one, while clicking with the right button will decrease the value by one. The middle button will reset the digit to 0. Of course you can also use the mouse wheel to take many repetitive steps. The size of the tuning steps is no longer an issue since you can click on any digit, be that 10Hz or 1MHz.
Screenshots
Below you can see some sample screenshots of GRig in in action. They illustrate the main features.
The Main Window
The main window gives you access to the most common functions including frequency, mode, filter and AGC controls. Besides being the most common, these CAT commands are available on most radios with CAT capability.
Radio Info Dialog
The info dialog gives you a quick overview of the CAT capabilities of your radio. The info dialog is accessible from the menu bar via the Radio menu.
Receiver Level Controls
GRig supports most of the available level settings for both RX and TX. This screenshot shows the receiver level controls. The transmitter level controls look very similar to this one.

|
GPredict is a real-time satellite tracking and orbit prediction software application. It can track an unlimited number of satellites in Earth orbit and display their real-time positions and other data in lists, tables, maps, and radar views. GPredict can also predict the time of future passes for the satellite, and provide you with detailed information about each past and future pass.
GPredict is different from other satellite tracking programs in that it allows you to group the satellites into several visualization modules. Each of these visualization modules can be configured independently from the others giving you unlimited flexibility concerning the look and feel of each module. GPredict will also allow you to track satellites relative to different observer locations at the same time.
