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 critical report on the hard keying of my K3 that I
have received since I started using it in May. I only operate CW and
have made well over 4500 QSOs with it so far, but have only recently
started using the NR option.
I believe I read something about this on the Reflector recently but a
search of the archives does not reveal anything - perhaps it was on
the K3 Reflector?
I carried out some tests this morning on 80 metres with a good friend
(a K2 owner) and someone who I can rely on to give me honest reports.
I didn't tell him what I was doing, but asked him to comment on the
hardness of my keying in position 1 and position 2. Position 1 was
without NR and position 2 was with it. He said the keying was
noticeable harder in position 2.
I am not a technical person, hence my question as to whether using
the NR option can effect the hardness of the keying? If it can, is
it fixable, please?
Thanks and 73 de Chris, G4BUE
