FUNCTIONS FOR RECEIVE

Auto tuning function
When an off-frequency signal is received, the Auto
tuning function tunes the desired signal within a ±500
Hz range in the CW mode, or a ±5 kHz range in the
AM mode. This function is usable only in the CW and
AM modes.
 Push [AUTO TUNE] to turn ON the Auto tuning func-
tion.
• “
AUTOTUNE
” blinks when the Auto tuning function is
activated.
• After 2 seconds has passed, the Auto tuning function
automatically stops tuning, even it’s still off frequency.
IMPORTANT!
When receiving a weak signal, or receiving a signal
with interference, the Auto tuning function may tune
the receiver to an undesired signal.
[AUTO TUNE] MAIN, SUB
Blinks
When you hold down [MAIN] for 1 second to turn ON the
Main/Sub band tracking function, the Sub band frequency
and mode are equalized to the Main band settings. If you
set the Main and Sub bands to the different antennas,
you can hear which antenna has better reception. Rotat-
ing [MAIN DIAL] changes the Main and Sub frequencies
in the same tuning steps at the same time. The direct
frequency entry in the Main band also changes the both
frequencies together. But rotating [SUB DIAL] changes
only the Sub frequency. So, you can change the tracking
separation between the Main and Sub band frequencies.
Rotating [MAIN DIAL] changes both frequencies, keep-
ing the amount of the frequency separation.
