I can't commit on the exact specs, but the winrado cards we used in the Coast Guard were awesome. A few years back we compared the Icom PCR 1000, the Ten Tec Rx320, and the Winradios. We were listening to shortwave stations interfering with our signal, and doing some signal anaylasis work on our own people. The Winradio was the best experience, the filters, and audio quality, and software in general beat the other two hands down. I still own the RX-320, and it is not as clear as the Winradio.
