5.1 Overview of Output Power Adjustment

5.1.1 Overview

To check for the TX output power and frequency of SSB mode, select [MENU] -> 1.
TEST -> 3.TONE TEST. For details, refer to information on page 5-32.
Make TX output power adjustment with power data. To make this adjustment, select
[MENU] -> 9.SERVICE -> 3.RT SETUP -> 4.TX PWR (FREQ), 5.TX PWR (USER
CH), 6.TX PWR (TUNE), or 7.TX PWR (SEL CALL).
• 4. TX PWR (FREQ)
This Sub-menu allows for making TX output power adjustment in steps of
1 MHz while in SSB, DSC, NBDP, or CW mode. Setting this Submenu to
<LOAD DEFAULT> will return the adjustment to the default.
• 5. TX PWR (USER CH)
This Sub-menu allows for making output power adjustment by user-specified
channel registered.
If frequencies and modes registered on the "USER CH" window fall within
the frequency band for which output power adjustment was made with the
Sub-menu "TX PWR (FREQ)" and the modes match each other, the relevant
will be set as the default of USER CH power data.
Conducting <LOAD DEFAULT> of this Sub-menu will return the adjustment
to that set with the Sub-menu "TX PWR (FREQ)."
• 6. TX PWR (TUNE)
This Sub-menu is common to all bands.
Note) Do not make unnecessary adjustment.
Conducting <LOAD DEFAULT> of this Sub-menu will return the adjustment
to the default of TUNE power data. TUNE power ranges from 10 to 15W.
• 7. TX PWR (SEL CALL)
This Sub-menu allows for making output power adjustment only with
2331.5 kHz.
Conducting <LOAD DEFAULT> of this Sub-menu will return the adjustment
to the default of SEL CALL power data.
