O MIC TONE CONTROL
This control varies the transmit audio response. Set the control to
produce the clearest and most pleasing audio. Bass response increases
as the control is rotated counterclockwise.

This control changes the transmit AM carrier level. Adjust with the
M IC GAIN set at minimum for a 40 watt carrier or 40% of full scale
indication with the METER SWITCH in the Po position. See page
32 for AM operation.
When using the VOX mode, speaker audio may sometimes activate
the transmitter accidentally. Adjust the ANTI-VOX CONTROL in
conjunction with the VOX GAIN in the IC-735 SWITCH PANEL to
eliminate this undesired T/R switching.
In the transmit mode, this switch selects one of three meter func-
tions.
(1) Po:
The meter indicates the relative RF output power
provided the METER SWITCH in the SWITCH PANEL
is set to the PO position.
(2) SET: Place the switch in the SET position to measure the
standing-wave ratio (SWR) of the antenna system.
Adjust the RF POWER CONTROL until the needle rests
at the SET position on the meter.
(3)
SWR: The front panel meter directly reads the antenna system
SWR after calibration as explained in step (2).
