<DIV><FONT face=Arial>We sample at 122.88MHz since that divides evenly to
standard sound card frequencies. This does need updating since we will be
able to achieve 2MHz of displayed bandwidth using the current USB2 interface to
the PC.</FONT></DIV>

The Mercury page at <A
href="http://hpsdr.org/mercury.html">http://hpsdr.org/mercury.html</A> says:<BR><BR>"the
board will contain it's own FPGA to undertake Digital Down Conversion (DDC) to
250 kSPS or less for transfer over the Atlas bus to the USB interface on the
OZY board."<BR> <BR> <BR>Earlier, I thought that the sampling rate
goal was going to be much higher to allow the host PC to archive wider chucks
of bandwidth like an entire ham, SW or AM
(broadcast) band.<BR> <BR>Is this just an old piece of information
that needs correction? If so, what is the real
target?<BR><BR> <BR>Chuck<BR>
