the short answer is yes for most cases. ?For example, if you use the
WSJT-X tune function the actual frequency is the set point (7.074) plus

is not true for all radios and some can be set to shift the transmitter
instead of the receiver.
Ok, so to help me get this straight...
I set 14000 kHz and switch to digi. Someone in WSJT-X transmits at 14001
kHz (14000 kHz + 1000 Hz). I can hear a 1000 Hz tone, and my WSJT-X will
show it at 1000 Hz mark. That's clear.
Now I still have 14000 kHz set, but switch to CW. My sidetone is set to
500 Hz. Someone transmits at exactly 14000 kHz. I will hear the 500 Hz
tone, right?
If someone transmits at 14000.050 kHz (50 Hz more than my set frequency),
I will hear 550 Hz, and if they transmit at 13999.950 (50 Hz less than my
set frequency), I will hear 450 Hz, right?
If someone transmits at 14001 kHz I won't hear it, because I'm centered
at 14000 kHz and the CW filter isn't wide enough to cover it.
If I press PTT, I will send a continuous wave of exactly 14000 kHz.
So, generally, when I'm sweeping the CW band in a digi mode and I hear
someone sending, I wouldn't be able to hear them when I switch to CW,
because I should first increase the frequency to zero-beat on them (so I
stop hearing them in digi mode), and then after switching to CW I would
hear them at my sidetone frequency.
Is it all correct, or am I wrong somewhere?
I am typing this on my phone at a concert with my wife. If you need more
info send back your questions and I will respond tomorrow.
Great, thanks!
