[Elecraft] K3 CW at 60-100 WPM...and beyond

[wayne burdick]

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.
