I don't know how Chen determines input overload - whether he's seeing digital overrun in the data or measuring clipping in the audio input. I suspect you are seeing the inevitable narrow range between hum/noise on the audio output or the high noise floor of the particular sound card and the limite

Using a SignaLink USB interface, I often see cocoaModem reporting input overload from strong signals on 20 meters with the noise barely visible on the waterfall. This occurs with both the K3 and the Small Wonder Labs PSK-20 driving the system. (The Icom 706 MK2G generates a lot more noise.) I r

Mr Nyquist would be happily surprised at that. With I&Q samples at 48kS/s each, you get a maximum of 48kHz, or one-half the total bandwidth. Not 48k+48k. So, with a 48k sample rate, you will get plus and minus 24k from center. Sent from tfox iPad On Aug 19, 2012, at 4:33 PM, "Joe Subich, W4TV
