BASIC OPERATION

Supplements
• When the forced Iransmission signal line is not connected:
Because the exciter will not automatically enter transmission mode, take the following steps
to implement tuning:
1. Manually key the exciter to begin transmission. The JRL-2000F measures the operating
frequency.
2. Stop transmission from the exciter.
3.
Transmit again and remain in transmission mode until the automatic tuning operation
is complete. Matehing data will be written into memory for the selected band or sub-
band.
• When Po is indicated in the central display:
This indicates that there is not sufficient input power to perform the automatic tuning operation.
Adust the power output control of the exciter to increase the drive Ievei. The JRL-2000F
can not perform automatic tuning unless there is more than approximately 20 W input.
• When A7 is indicated in the central display:
This indicates that automatic tuning has not been completed successfully. Checkall antenna
connections, antenna VSWR and exciter connections and try again.
• When the color of the MATCH LED is orange:
This indicates that antenna matehing has not been completed successfully. Checkall antenna
connections, antenna VSWR and exciter connections and try again.
This completes the automatic tuning procudure. The JRL-2000F can be used in any band
that has been tuned by the above Operation. By implementing the automatic tuning operation
in advance for all frequency bands and sub-bands that you plan to use, antenna switching
and matehing data can be quickly recalled for instant QSY.

• ln some countries, including the United States of America, linear amplifier operation
above 24 MHz is not possible. However, the JRL-2000F can be used as an
antenna tuner in any band.
• The VSWR value of the antenna itself is displayed on the VSWR meter on the
front panel. This reading will not change even after tuning has been completed.
lf the antenna VSWR is too high, it may cause radio interference.
• During automatic tuning the power amp is switched OFF even if the
~
switch
is set ON. After tuning, the
~
switch will automatically return to its previous
state.
• The antenna tuner is bypassed during receive operation.
