Ok, I agree, Bob. But where should the the tuning frequency be then? Shouldn't
it be at the displayed frequency, at the "carrier"-frequency for USB or LSB?
At my radio v1.4.5B15 when the displayed frequency is e.g. 3.775MHz, the tuning
frequency is 3.7756MHz in both LSB or USB. So it is plus 600Hz, the CW pitch
frequency.
An other observation: when in AM on 3.775MHz, the tuning frequency is 3.7646MHz
(-10.4kHz). If this is not unique to my radio, this must be a bug?

The tuning should be such that the carrier frequency remains identical
in both cases. So that if you are tuned to 14.150 in the USA and are
using USB, you are "legal" if you then switch to LSB, you are not
legal. This can easily be seen by tuning in a shortwave broadcaster and
turning on the panadapter. Place the carrier at the center. Go back
and forth from USB to LSB and you will see the carrier stays in the
center but the "green band" swaps sides on the carrier.

Hi all
In LSB the tuning frequency is in the USB, so when tuning, you don't
disturb the qso you would like to join. When in USB it would be nice
to have the tuning frequency in the LSB. Hw?
