6. REF OSC (-127~+127): 0

This Submenu-3 is used to make setting of frequency of the reference oscillator: 36

MHz VCTCXO on the TX board. If transmission frequency deviation does not fall

within the specified range (i.e., within ±10 Hz), make frequency adjustment using the

Submenu-3 "REF OSC."

This frequency should be any of the PLL reference frequencies of TX, RX, WR1, and

For detail, refer to information on page 5-29.

This Submenu-3 is used to make setting of variable range of the clarifier.

To use the clarifier,

• select [MENU] -> 5.SYSTEM -> 7.RX SETUP -> 3.CLARIFIER, and then set

"CLARIFIER" to "ON"; or

• select [MENU] -> 5.SYSTEM -> 2.KEY ASSIGN, and then assign "CLARIFIER"

to the function key.

1) The clarifier is enabled in SSB, LSB, and CW modes, making reception frequency

variable in steps of 10 Hz.

2) When the clarifier gets activated, even if the reception frequency or mode (SSB,

LSB, or CW) is changed, the set clarifier value will remain valid.

For the set value of the clarifier, DDS frequency data of 1st Lo on the RX board is

changed and displayed.
