Hamradio / Tech

I have recently bought the new Softrock Esemble II Receiver. This is a Sofware Defined Radio, it’s based on Si570 a local programmable oscillator and an Atmel ATTiny85 micro-controller unit, which works as a USB device. The Quadrature Sampling Detector (QSD) acts as an output mixer, so then you need a stereo soundcard with a good bandwidth. Today I have conducted the first test.
