Just use the SPOT switch and match the pitch of the desired signal with
the pitch of the SPOT tone. After a while, your ears will get accustomed
to that pitch and you'll rarely use SPOT again.

Also, if you use narrow selectivity (0.10 kHz) and/or the audio filter,
the received signal will already be near the center of the passband (if
CAL FIL is properly done), which means you are already close to zerobeat
with the signal.
