Thanks Phil,<br>
<br>
As I see I need to upgrade my hardware. I'm still Ozy user since
most<br>
of the time I'm running my HPSDR @ 48 kHz, there's no need for<br>
higher sampling rates for me.<br>
<br>
<br>
Thanks again !<br>

73's<br>

<div><font face="Arial" size="2">You may care to do some tests on
you system using KISS Konsole since I suspect you are dropping
packets between the PC and HPSDR hardware. If you are only
losing the odd packet then you are not going to hear them.</font></div>
<div> </div>
<div><font face="Arial" size="2">The Metis Ethernet code has a
packet number included in each data frame both to and from the
PC. KK will indicate if a packet is lost and what the
expected and received packet numbers are. Similarly Metis
will light a LED if it misses a packet.</font></div>
<div> </div>
<div><font face="Arial" size="2">Using KK with Metis at 192ksps I
have never seen a missed packet in either direction - in fact
I had to deliberately send incorrect packet numbers to check
the code was working!</font></div>
<div> </div>
<div><font face="Arial" size="2">I'm also currently doing some
work that involves time stamping the data from Mercury via
Metis - again no dropped packets. </font></div>
<div> </div>
<div><font face="Arial" size="2">The PC has absolutely no idea
what the sample rate is of the data it is being sent. It's not
acceptable that an SDR can't be used for DRM, SSTV etc - this
needs to be investigated and corrected.</font></div>
