tone pitch (from 300 ~ 1050 Hz, in 50 Hz incre-
ments). The TX sidetone, the receiver IF passband,
and the display offset from the BFO (carrier) fre-
quency are all affected simultaneously. The Pitch
control setting also affects the operation of the CW
Tuning Indicator, as the center frequency of the CW
Tuning Indicator will follow the setting of this con-
trol.

VOX
]
Knob
The inner [ VOX
] knob sets the level of microphone
audio needed to activate the transmitter during voice
operation when the [
VOX
] switch is actuated.
[ DELAY ] Knob
The outer [ DELAY
] knob sets the hang time of the
VOX circuit for voice operation, and the keying
delay for CW operation.
For voice operation, this knob sets the hang time,
between the moment you stop speaking, and the
time the transmit is switched back to receive. For
smooth operation, adjust the VOX so the transmit
switches to receive when your comments have
ended.
For CW, this knob sets the automatic transmit to
receive keying delay for “Semi-break-in” operation.
Adjust this just long enough to prevent the receiver
from being restored during word spaces at your
preferred sending speed.

The hang time of the VOX circuit will show for 3
seconds in the lower right corner of the Main Dis-
play whenever the outer [
