You are right about all of that, but the original post (and the original QST
letter to which it referred) appeared to be talking about copying a single
signal, rather than the complex process of discriminating between two signals
close to each other, and it implied some near-universal
I prefer the Golden Ratio for my solder, but 63/37 is often the best I can
find. Sadly.

I don't have perfect pitch, but I have pretty good pitch. For example, I
can tune in a RTTY signal without any tuning aids.
As a high speed CW guy, I once experimented with various base frequencies to
see if it affected my upper speed limit. My hypothesis was since square
waves are odd harmonic
Unless you're using APF, in which case a few Hz might make a
difference.
Like others, I don't buy the musical CW pitch theory either. However,
the pitch of a CW note IS important, and there may be different
optimum pitches for various different reception conditions (assuming
your hearing response
There is a study from 1992 that tested recognition rate vs pitch frequency.
Unfortunately only a few tones were tested, but at least one can infer that
a low tone is preferrable. This is in Montnemery, Peter, Bengt Almqvist, and
Sten Harris. Recognition of telegraphy signs at different listening
Are you saying they don't?

Shouldn't be needed, however..

Hi Jim,
My only gripe is that the K3 choice range doesn't go down to 400 Hz. I'd like
to use 440, a pure standard A.

It certainly does - it goes down to 300 Hz. However, I find A4 a bit
low for my taste - I'm satisfied with a 3.88 Hz error on B4 or 3.25 Hz
error on C5.

I'm using 1.69 beta firmware that stops at 400 Hz.
I'm just happy that the 1 kHz sidetone that was almost standard for many
years is no longer popular. All of my radio licensing CW tests at the FCC
offices used 1 kHz. That made my brain ache, not to mention the tendency for
it to echo when using
What 1.69 beta firmware?

I assume you are talking about the KX3 beta firmware. This discussion has
been about the K3 sidetone pitch. Production firmware level for the K3 is
4.67.

Gee, maybe it's a good thing radio wasn't invented back in the days when A

Bad assumption. Without a model mentioned I was thinking about the KX3, not
the K3. 300 Hz is correct for the K3.

Good point, but I have found that a lot of SKCC members enjoy using their
bugs *instead* of a 'straight key', so I can understand the interest.
SKCC might better be called the MKCC for Manual Key Century Club.
I have run into a lot of bugs on Straight Key Night sponsored by the ARRL
too.

I have never found electronic bug modes to be satisfactory for me.
With a mechanical bug, there is positive feedback to the keying that is
important to me - that is entirely missing from an electronic keyer set
to bug mode. It may be my shortcoming, but I just cannot get the hang
of it.

But he wouldn't be using a bug. He'd be using the electronic keyer in
the KX3. Dots would be electronically generated even if dashes weren't.
Straight keys, bugs and cooties (I use all three) explicitly meet the
SKCC rules because they are mechanical keys. An electronic keyer
probably isn't
I agree with you and Don. My previous interest in a bug mode was that when

My IC746PRO has a Bug Mode where it would emulate a bug using physical

Its sorta neat to play with, but as others have said, using paddles to
emulate a bug makes my brain wonky since I go by feel (even at my 10wpm).
An option would be nice for both the K3 and KX3 since it makes the rig
