Hello Mark,
I've been operating my FLEX-5000A for about 2 years now on cw. I used to
use an external Logikey K-3 keyer to key the radio while using the
keyers sidetone, but have lately been just connecting the paddles
directly to the radio and using the sidetone of the FLEX-5000A. My
computer up until recently has been a single-core 3GHz P4 with 3GB RAM
and XP Pro, so pretty much the same as yours with the exception of
memory which I don't think comes into play here.
The settings I have always used have been:
Setup > Audio > Buffer Size : 1024
Setup > Audio > Sample Rate : 96000
Setup > DSP > Options > Buffer Size (CW) (RX) 4096
Setup > DSP > Options > Buffer Size (CW) (TX) 2048
Firewire Control Panel settings:
Sample Rate: 96KHz
Buffer Size: 1024
Operation Mode: Safe Mode Level 1
Some general comments:
-- You should see a significant improvement in latency by changing your
Setup > Audio > Buffer Size from 2048 to 1024.
-- Be sure that the Firewire Buffer Size setting exactly matches the
Setup > Audio > Buffer Size setting.
-- For optimum rx filter shape factor, you should select the largest
buffer size. You indicate that you are currently using 2048/1024, but I
would recommend that you change that toe 4096/2048. I don't think you'll
see much (if any) difference in latency with the monitor, but your rx
filter performance will be improved.
-- If you can get away with it on your machine, try running with the
Firewire 'Operation Mode' set to: 'Normal'. Mine will run that way, but
I have an occasional dropout with that setting, so I've been keeping it
at 'Safe Mode Level 1' where it runs perfectly.

I've had a few months to play with my new F5K and I have a few questions
about the proper operation of the radio, especially in CW mode.
The computer is a 3 GHz Dell P4 (single core) with 512MB RAM with XP Pro.
Everything has been working fine and I had no problem getting everything to
work when I first got the radio.
Last weekend I did my first software upgrade to the latest PSDR, FireWire,
and firmware versions. The release versions - not any of the experimental
stuff. All went well and I had no problems with the upgrades.
I had read some comments (before I purchased the F5K) that the CW
performance (in transmitting) was not very good. Others say it is great.
Unfortunately, I am falling into the first category.
My first QSO with the new radio was on CW. I was using my MFJ keyer as an
external keyer to the radio. I discovered very quickly that I couldn't use
the Flex's Monitor function to listen to my sending because of a delay
between key closure and the sidetone audio. So I turned the Monitor off and
turned up the volume on the keyer. This worked OK. I also tried connecting
the key (dual paddle iambic type) directly to the radio. Again I found that
the delay made sending correct characters impossible. But in this
configuration I do not have the option of turning the Monitor off. I can't
believe that such a fine radio has such a problem with CW. So, my question
is what do I need to do in order to send CW?
Here are the basic settings (also in the firewire driver):
Under the Audio ->Primary Tab: Buffer Size=2048 Sample Rate=96000
There are additional settings for Phone, CW, and Digital here:
DSP->Options For Phone/CW/digital
The CW setting is currently: 2048/1024
I have played around with the CW settings but I cannot see any difference.
I am guessing that some of these settings need to be changed but I haven't
found the right combination yet.
If any of you CW ops out there would be so kind as to share your settings I
would be very thankful!
