3.2 RT SETUP
3-10
13. COUPLER THROU (OFF, RCVD, DIFF)
The receiving signal can bypass the tuning circuit in the antenna coupler.
OFF
The signal received by the antenna is sent to the transceiver unit through the tuning
circuit in the antenna coupler.
RCVD
The received signal bypasses the tuning circuit in the antenna coupler.
DIFF
When the transmission frequency and the receiving frequency are different, the
receiving signal bypasses the tuning circuit;
1) If the receiving frequency is 1.6 MHz or less.
2) If the receiving frequency is less than 4 MHz and different from the
transmission frequency.
3) If the receiving frequency is 4 MHz or more and different 1.2 MHz from the
transmission frequency.
4) With the RT scanning.
*When CR61 (THROUGH) on COUP board is on, the receiving circuit is
“THROUGH”.
14. TONE

15. TX POWER (FREQ.)
Output power is adjusted for each frequency. See page 7-4.
16. TX POWER (USER CH)
Output power is adjusted for user channels. See page 7-6.
