Linear amplifer mode
The JRL-2000F operates as a linear amplifer when it is in the OPERATING state, and
both the
-1
and
(PA
switches are set to the
ON
position. During exciter transmission,
the XMT LED is lit. Also, an idling current of approximately 6A is supplied to the
PA
unit during transmission; during reception, the current is OA.

Important
In some countries, including the United States of America, linear amplifier operation
above 24 MHz is not possible.
There is a time lag of approximately 0.6 seconds between the time the PA LED
is lit and power is actually supplied to the power amplifier.
The JRL-2000F can not be put into the Linear Amplifier Mode if:
1.
The operating frequency is not indicated in the central display; or,
2.
The frequency band indicated in the central
display is blinking.
In either case, implement the
SET
operation as described in section 6.4.
The JRL-2000F can not be put into Linear Amplifier Mode while transmission
is in progress.
