OTHER FUNCTIONS

I Duplex operation
Duplex communication uses 2 different frequencies for trans-
mitting and receiving. Generally, duplex is used in communi-
cation through a repeater, some utility communications, etc.
During duplex operation, the transmit station frequency is
shifted from the receive station frequency by the offset fre-
quency. Repeater information (offset frequency and shift di-
rection) can be programmed into memory channels. (p. ??)
qSet the receive frequency (repeater output frequency).
tRight-click [DUP] to display the offset frequency setting
screen.
ySet the desired offset frequency within 0.000000–
1000.000000 MHz range, then click [OK].
wLeft-click [DUP] to set the duplex direction from OFF (no
indication,) DUP–, or DUP+.
eClick [MONI] to monitor the transmit station frequency (re-
peater input frequency).
The displayed frequency shifts the offset frequency when
monitor function is in use.

I IF filter selection
Increasing or decreasing the width of incoming signals can
help eliminate interference. Available filters vary according to
the receive mode. See the table below.

widths.
I Attenuator function
Strong signals (such as from broadcast stations, pocket beep-
ers, nearby amateur radio stations, etc.) can cause distortion
of receive signals. The attenuator function can reduce signal
strength of interfering signals by approx. 20 dB.
➥ Click [ATT] to turn the ATT (Attenuator) function ON or
OFF.
• "ATT" appears when the ATT function is turned ON.
