Using a SignaLink USB
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

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

they can display whatever they want, but as to actual, significant data

My experience is the same as Tim's. I have an M-Audio Audiophile 2496 PCI
which is 96Khz card and I get a total bandwidth of 96Khz. With my 192Khz
Infrasonic Quartet PCI I get a total of 192 Khz. I use the LP-PAN with NaP3.

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.

Jeff,
In addition to the cable, you will also need to be sure that your
laptop's sound card accepts stereo input. Panadapter software requires
stereo input (I and Q channels). Some laptop input jacks will only
accept mono signals, even though the laptop's sound card itself is
stereo. My newest

Hi Lance and Jeff, I am also waiting with baited breathe for my KX3. And I just
happen to have a NOMIC laying around that I am not using so I am going to do
your mods. What a cool conversion and such great docs and pics. Thanks a
