>the Navigator provides high-quality soundcard

"USB Audio Codec
         Standard Microsoft Audio Device
            2 channel Output DAC 16 bit
            2 channel Input ADC 16 bit
            Codec operates at sampling rates up to 48,000 Hz*
            *Most Amateur software applications set the sampling rate to
11,025 Hz."

        Sounds like a nice product overall but the soundcard
will not be enough for decent SDR/DSP processing on the
K3's IF output.  You really want 24 bits at 96 kHz minimum
and preferably 192 kHz.

                                    73,  Bill  W4ZV

For my SDR software I have the Edirol FA-66, but please don't ask me about
the SDR console I'll be writing in 2008 / 2009!
