A computer aided transceiver CAT is a device used by radio amateurs for controlling a transceiver radio receiver using a computer. Conventional transmitters are manually controlled and used to transmit voice using buttons, dials, etc. However, advances in electronics have come to market devices that can be controlled by a computer and allowing digital modes such as packet radio and also the use of satellite tracking, because it can continuously change the device's frequency according to the Doppler effect. A CAT interface is a piece of hardware that connects between the PC and a radio that provides a connection to allows the radio and the PC to communicate with each other. The CAT interface provides the signals to and fro via correct voltage levels and in the case of a Universal Serial Bus USB CAT interface it requires a "protocol" for communication but communication itself is down to the radio and the software on the PC.

Forgot Password? Software Defined Radio attempts to place much or most of the complex signal handling involved in communications receivers and transmitters into the digital DSP style. In its purest form, and SDR receiver might consist simply of an analog-to-digital convert chip connected to an antenna. All the filtering and signal detection can take place in the digital domain, perhaps in an ordinary personal computer.

Read Full Statement. While the previous post still holds some extremely valuable information, a lot has changed in 3 years So we thought it was time for an update. Like last time, we tried to include as much diversity in terms of prices, applications, frequencies, and ease of use.
Computers have revolutionized the ham radio hobby. Before home computers became commonplace, amateur radio was largely analog. Users manually tuned up and down the radio spectrum to search for signals, and used paper and pencils to copy messages and take notes. Today, nearly every aspect of the hobby can be done on a computer.
