(
AUTOMATIC GAIN CONTROL
)
If the optional dual Receive Unit (RXU-9000) is installed, AGC operation is identical on either VFO.
As a reminder, there is no difference in the fundamental performance of the two VFOs. Please see page 63 for details.
VFO-A Band AGC Selection
Rotate the VFO-A
AGC switch (# ) to select the de-
sired receiver-recovery time constant. For most operation,
we recommend the “AUTO” mode.
VFO-B Band AGC Selection
1. Pressing the
SUB RX switch (# ) will engage
Dual Receive operation.
When the imbedded LED grows green, this is your
confirmation that Dual Receive is in operation.
2. Rotate the VFO-B AGC switch (# ) to select the
desired receiver-recovery time constant.
MUTE FEATURE
--
VFO-A
--
If the optional Dual Receive Unit (RXU-9000) is installed, during Dual Receive operation it is possible to mute the VFO-
A audio temporarily, without touching the setting of the AF GAIN control (# ) for the VFO-A.
This capability is particularly useful if you wish to concentrate on the signal being received on the VFO-B during Dual
Receive operation.
Press the VFO-A band’s RX LED/switch (# ).
The VFO-A audio will be silenced, and the green LED in
the RX switch (# ) will blink. To restore reception on
the VFO-A, just press the blinking RX switch/LED
(# ) once more.
