<DIV>I would like to echo John's comments below, but further add that in my
case, I cannot</DIV>
<DIV>really detect any latency at all (none while using the PowerSDR MON) on CW
and while </DIV>
<DIV>listening on my FT-1000, I could not detect any noticeable latency. I use
HPSDR as</DIV>
<DIV>my main rig on HF on SSB & CW and also on 70 cm & 23 cm EME as the
28 Mhz IF.</DIV>
<DIV> </DIV>
<DIV>I use the internal keyer as well as the W5SXD package, and I also have used
an external</DIV>
<DIV>Logikey Model K-3 memory keyer, all with NO issues. </DIV>
<DIV> </DIV>
<DIV>I have not tried CW with KK yet, but have tried full duplex on SSB and
it looks as if given</DIV>
<DIV>the proper isolation, one can run true QSK as in the OLD days with an
electronic T/R switch.</DIV>
<DIV> </DIV>
<DIV>BTW I am not running a "super" computer, just Athlon 2 Ghz dual core
processor and 2 Ghz</DIV>
<DIV>RAM. I think one of the contributing factors to a lot of folks issues is
the USB port performance.</DIV>
<DIV>Again, I can't back this up with statistics, just with usage.</DIV>

High Performance Software Defined Radio Discussion List *****<BR><BR>Ken and
the rest,<BR><BR>I am a 100% CW operator with three weeks of HPSDR operation
and 60 CW QSO's <BR>under my HPSDR belt. I find no, repeat "no" problems
using the native Power <BR>SDR keyer and keying monitor. From the
perspective of the radio operator, <BR>there is no apparent latency or delay
from my paddle activation to the <BR>monitor output. Of course, there is
a definite latency between the monitor <BR>output and the actual RF output as
monitored on a separate receiver. The <BR>native keyer also permits
optimization of the wave form of the keying <BR>signal. I have made some
small adjustments to suite me and have received a <BR>number of spontaneous
compliments on the keying etc.<BR><BR>In my combined experiences with the Flex
1000 and 3000 and now my HPSDR rig, <BR>the exceptional CW performance using
the native Power SDR keying functions <BR>with HPSDR contrasts with the rather
frustrating experience with Power SDR <BR>on CW with the Flex rigs.
These two different systems should not be <BR>confused.<BR><BR>If anyone has
further questions about CW operation with HPSDR please ask <BR>them.
Maybe I can help.<BR><BR>Regards,<BR>John Petrich, W7FU
