The K3 KEYOUT can handle up to 200 volts as long as it is a positive
voltage. So +20 volts is no problem.

This sounds like your K3 is configured for DTR keying. Go to the CONFIG menu

Thanks Stewart.
I loaded the latest firmware this morning (I was using 2.20) but
before I did that, I tried monitoring my transmitted signal on
another receiver, on the same 80m frequency that I did the test with
my UK friend yesterday morning. I cannot tell any difference to the

I just keyed my K3 with and without NR (all settings) while looking at the
keying waveform. I used both the internal keyer and an external computer
interface for keying and could not see any effect on the 5 mS rise and fall
times related to NR settings or with NR on or off.

Whilst in QSO with a European station recently, he asked if I was
using a K3. I told him that I was and asked why he was asking. He
said he thought I was using a K3 as he recognised the hard keying,
having heard it on some other K3s. I was using the NR option at the
time.
This was the first
Thanks again to all who responded on- and off-line to this subject.
Two things I learned here: There are external keyers that provide superb
support for high performance contest software, but also, great software can
indeed produce great CW over serial or parallel ports without the extra
hardware
