The purpose of the duplex function is to allow an operator the
option of transmitting and receiving on two different frequencies.
The 1С-475Н provides duplex operation using either of the follow-
ing two methods:
(1) Operating on user-programmed offset frequency.
(2) Operating on УЕО A and VFO B with the [SPLIT] SWITCH.
The offset frequency can be programmed for use in duplex
operation.
Following is an example for programming the offset frequency at
7.6MHz.
1) Push the [DUP] SWITCH to set the duplex mode.
2) Push the [SET] SWITCH. The subaudible tone function (U.S.A.,
Australia versions) must be turned OFF when resetting the offset
frequency.
3) Rotate the TUNING CONTROL to '7.600.0" for the desired
offset frequency of 7.6MHz.
4) Push one of the following switches to return to the normal
operating mode: [TONE], [DUP] ог [CHK].
Following are examples for duplex operation using 438.8000MHz
for receiving and 431.2000MHz for transmitting with a 7.6MHz
fixed offset frequency in FM mode.
1) Select 438.8000MHz with the TUNING CONTROL and push the
[FM] SWITCH.
2) Push the [DUP] SWITCH to set the -DUPLEX mode.
