Default BFO, CW, sideband question

And by the way, I do have an older radio, a Kenwood TS 830, not a modern
radio. My radio-display shifts on transmit to a frequency 800 Hz higher than
what was displayed on receive.


The 'true' CW frequency would be that of zero-beat as opposed to where
you 'hear' the signal. The rig assumes that you are listening to a beat
note offset by about 800 Hz and compensates accordingly on transmit.

So I assume it displays the carrier frequency on transmit, while on receive
it displays the heterodyned frequency, which on my radio happens to be
lower, but as some indicated in this group, this is an arbitrary choice made
by the people at Kenwood.


I think we're saying the same thing.


It is also confusing me that I can't receive SSB on the lower bands using
USB (and a slight retune), I need to use LSB.
I don't know why since I learned that the two sidebands contain the same
info.


Alas, a SSB station is only transmitting one of the sidebands! This by
convention is LSB on 40 and below and USB on 20 or above. If a station
WERE to xmt USB on 75 meters, for instance, you would have to use the
USB position and would not be able to detect it in LSB.
