Project DescriptionSDR-Widget is an interface based on the Atmel AT32UC3A3 microcontroller that provides the following functionality to SDR circuits such as the SoftRock.
High quality audio using the USB Audio Class standard PTT control Si570 control SWR metering PWR metering PA Heatsink Temperature metering PA bias adjustment LCD display Rotary Encoder Input Filter bank switching control CW paddle The interface also aims to be used as a general platform for future experimentation with SDR peripherals.
There is a pdf file at the Download page with photos of the hardware.
