Radio/PC Interfaces

There are many brands of interface available to connect a PC to an amateur radio transceiver. They all do essentially the same thing. They key the radio to transmit, pass a signal based on the mode of operation from the PC to the radio, then un-key to go back into receive mode. Some automatically bypass the microphone during transmission but allow the operator to override the computer simply by keying the mike. One example is the RIGblaster but there are others. They generally work with any PC soundcard based software, digital or analogue.
