Hi all,
We have implemented a client-server software defined radio program based on
John Melton's work.
Among many additions and features, we have used Codec2 as the codec for the
Microphone input to the client. The encoded mic audio is transported VoIP
fashion to the server. decoded and then processed to IQ signals for
transmitting through hardware such as the Softrocks.
