Hi Pete:
The K3 reads the actual transmit carrier frequency. That's the
suppressed
carrier frequency in SSB and the actual carrier frequency
Hi Rich - a very lucid reply, and you apparently understood what I was
saying, despite my RIT mis-statement.
For some reason, I was operating under the mistaken impression that the
sideband used for CW followed the sideband convention for SSB. I went
straight to the Cady book, unfortunately
One of the features of using LSB convention for receiving CW is that
when you tune the dial to a lower frequency the pitch of the received
audio gets lower.
In fact, that was the old timer's test back in the day of
non-single-signal receivers... if you tuned to a lower frequency and the
pitch

It's been many decades since the sideband used for CW switched with the USB

Pete,
When receiving in CW-USB and you tune to a lower pitch, you will be
tuning to a higher frequency.
If the receiving station is also using CW-USB, the pitch in his receiver
will go up.
I just verified that on the test bench.

So, short answer to your question: It depends.
Exactly...it depends on whether the DX station is receiving CW in USB or
LSB. BTW I've often wondered which is most predominant for contesters.
Since the K3 is normally in LSB, I suppose that's a good assumption given
I'm having a hard time getting my head around this. My radio is on
3507.02 USB-CW, with a 500 Hz Pitch setting. I change the Pitch setting
to 300 Hz, and the display still reads 3507.02. What is this
frequency? The suppressed-carrier frequency plus the CW pitch? Does
that mean that when I
Pete.
All Elecraft radios that I know about display the transmitted carrier
frequency in CW and the suppressed carrier frequency in SSB mode.
Your sidetone pitch setting is related to properly tuning a CW signal
and knowing its frequency. If you tune the received signal to a pitch
the same
Hi Pete,
In CW mode, the K3 reads the actual transmitted frequency. Since normal
CW uses lower sideband on the K3, this means that on 3507.2 in normal CW
mode, with the pitch set at 500 Hz the suppressed carrier frequency is
3507.7 kHz (500 Hz above the signal frequency). If you change the

This link adds one more piece of information to the discussion. The K3 has two
modes that need to be understood.
