Hi, Mark
I use my Flex 5KA daily on CW. Seems to work fine. However, I use
CWTYPE, a small keyboard program that keys a serial port handshake line.
Since I use com0com, all this is internal so no external wires. I've had
nothing but good comments on CW by everyone I talk to. Have never tried to
key it externally. And right on the monitor function. Never tried it with
CW, but quickly decided the delay with SSB was driving me up the wall - made
me stutter! So quickly quit using that.

Subject: [Flexradio] Proper settings for CW
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!
