What do I need to run JVComm32?
Here, interface means a kind of modulator/ demodulator that connects your computer to your receiver/transmitter. It transforms the audio data from the receiver into digital data that the computer can read. On the other hand, the interface transforms the digital data that the computer delivers into an audio signal that can be fed to your transmitter.
Currently, JVComm32 runs with standard 16 bit sound cards, the brand new EasyDSP interface by Ulrich Bangert, DF6JB (transmit and receive), the PTC-II DSP multimode PACTOR-Controller by SCS (receive/transmit, transmit not guaranteed), and the brand new HariFax IV interface.
There are some other hardware manufacturers, who are currently working on the development of interfaces that are compatible to JVComm32.
If you want to construct you own interface, you can get technical information on how JVComm32 manages the data transfer from and to the interface.
