MIC RF PWR Knobs
MIC Knob
The inner [ MIC
] knob adjusts the microphone input
level for (non-processed) SSB transmission.
A
DVICE
:
ˆ If you adjust the MIC Gain while speaking in a
somewhat-louder-than-normal voice level, watch
the ALC level and adjust the MIC Gain so that the
ALC reaches just to the right edge of the ALC scale.
Then, when you speak in a more normal voice level,
you’ll be certain not to be over-driving the mic am-
plifier stage.
ˆ The Sub band (VFO-B) frequency display will show
the relative microphone gain level for 3 seconds
whenever the outer [
RF PWR
] knob is turned.
You may disable this feature (displaying the rela-
tive microphone gain level) via Menu item “ 015
diSP LVL IND .” See page 117 for details.
RF PWR Knob
The outer [ RF PWR
] knob is the main RF Power out-
put control for the transceiver, active in all operating
modes. Clockwise rotation increases the power out-
put. Adjust this control for the desired power output
from the
FT-2000D .
A
DVICE
:
The Sub band (VFO-B) frequency display will show
the RF Power output for 3 seconds whenever the outer
[
RF PWR
] knob is turned.
You may disable this feature (displaying the RF Power
output) via Menu item “
015 diSP LVL IND .” See page
117 for details.
VOX DELAY Knobs
VOX Knob
The inner [ VOX
] knob sets the gain of the VOX cir-
cuit, to set the level of microphone audio needed to
activate the transmitter during voice operation while
the [
VOX
] switch is engaged. The [
VOX
] switch must
be switched “ON” to engage the VOX circuit.
DELAY Knob
The outer [ DELAY
] knob sets the hang time of the
VOX circuit for voice operation and keying delay for
CW operation.
During voice operation, this knob sets the hang time,
between the moment you stop speaking, and the auto-
matic switch from transmit back to receive. Adjust this
for smooth VOX operation, so the receiver is only ac-
tivated when your transmission is ended and you wish
to receive.
For CW operation, this knob sets the keying delay,
between the moment you stop sending, and the auto-
matic switch from transmit back to receive during
“Semi-break-in” operation. Adjust this just long enough
to prevent the receiver from being restored during word
spaces at your preferred sending speed.

DVICE
:
The Sub band (VFO-B) frequency display will show
the hang time of the VOX circuit for 3 seconds when-
ever the outer [
DELAY
] knob is turned.
You may disable this feature (displaying the hang time
of the VOX circuit) via Menu item “
015 diSP LVL
IND .” See page 117 for details.
