25. VOX -o- DELAY Knobs
VOX Knob
The inner [VOX] knob sets the gain of the VOX circuit, 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.
In the voice operation, this knob sets the hang time, between the moment you stop
speaking, and the automatic switch from transmit back to receive. Adjust this for
smooth VOX operation, so the receiver is only activated 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 automatic 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.
26. SUB SQL Knob
This knob sets the signal level threshold at which Sub (VFO-B) receiver audio is muted,
in all modes. It is very useful during local rag-chews, to eliminate noise between
incoming transmissions. This control is normally kept fully counter-clockwise (off),
except when scanning and during FM operation.
27. SUB AF GAIN -o- SUB RF GAIN
AF GAIN Knob
The inner [SUB AF GAIN] knob sets the Sub (VFO-B) receiver’s audio volume level.
Typically, you will operate with this control set past the 9 o’clock to 10 o’clock position.
RF GAIN Knob
The outer [SUB RF GAIN] knob is the Sub (VFO-B) receiver’s RF gain control, which
adjusts the gain of the Sub (VFO-B) receiver’s RF and IF amplifier stages. This control
is normally left in the fully clockwise position.
28. AF GAIN -o- RF GAIN Knobs
The inner [AF GAIN] knob sets the Main (VFO-A) receiver’s audio volume level.
Typically, you will operate with this control set past the 9 o’clock to 10 o’clock position.
