We've had a number of requests for higher-speed CW on the K3. Until
now, the upper limit was just over 60 WPM. But I now have a field-test
firmware release available that allows speeds of over 100 WPM when PTT
is used. In fact I was able to hit 120 WPM in lab tests. (When using
VOX, or hit-the-key CW, the upper limit is still around 65 WPM.)
The RS232 jack on the K3 has provisions for both PTT and KEY generation
by PC-based CW keying applications. If you use a keyer or other device
that doesn't provide for PTT, you'll need to activate PTT manually.
This is typically accomplished with a foot switch, although you can
also just tap the XMIT switch on the K3.
If you're a high-speed CW op and would like to test this new firmware,
please contact me directly. We'd like to go to beta with this firmware
soon, so any testing you could do today would be a big help.
