Turn your PC into a transceiver by launching the Java-based application communicating over a simulated Ionosphere environment called the HamSphere covering frequencies of 6m to 160m Ham band. Double-sideband modulation is included, all settings are configurable.
I recently started using Ham Radio Deluxe and I'm really impressed with the features and capabilities it offers. I'm able to easily connect my external radio frequency hardware to my computer and control the settings. The integrated DX cluster, satellite tracking interface, logbook, and other tools make it easy to keep track of my progress and stay organized. The software also supports a wide range of radios, including Yaesu, ICOM, Elecraft, Ten-Tec FlexRadio, Kenwood, and others.
