Hi,
Here's a forward from the linux-hams mailing, and I hope Jonathan
will let me transcript his very interresting mail here.

Has anyone of you heard about this SDR? It looks quite promising,
and I happen to currently look for real hardware (I have a laptop,
firewire, and USB 1.1).

Hi Folks
I came across the SDR-14 software defined receiver whilst trawling the
web. It looks very interesting for a number of uses. The supported
software is Windows based but if they release the specs then everything
should be alright. I am happy to see that they are using USB as the PC
to radio connection mechanism.
According to the blurb:
===========================================================
The SDR-14 is a 14Bit Software defined radio receiver. It offers a broad
range of demodulation and spectrum analyzer functions. The hardware
directly samples the whole 0-30 MHz band using a sampling rate of
66.666 MHz. This sampling rate allows the SDR-14 to capture the whole
0-30 MHz band or any nyquist band up to 250 MHz with little degradation
in performance. The digital data is processed into I and Q format using
a direct digital converter (DDC) . The I and Q data is then sent to the
PC for processing using a high speed USB interface. The SDR-14 also
supports high resolution spectral captures using it's 512Kx16 deep
memory.
All of the demod and spectral functions are done on the PC side.
Supported formats at this time include USB, LSB, AM, FM and CW.
Some of the possible uses of the SDR-14 hardware include:
Digital demodulation of signals in the 0-250 MHz bands.
High quality spectral captures as wide as 30 MHz and resolution
bandwidths as low as 0.02 Hz
Ionospheric and band condition monitoring.
Power, noise figure and antenna noise measurements.
Radio astronomy observations and coherent signal detection in noise.
Recording a 100KHz segment of any band (0-250 MHz) to hard drive in real
time.
Panoramic adapter for use with communication receivers like the AOR5000
and IC-R8500.
=============================================================

I have no connection to the company, I just thought it interesting.
