Controls Under Access Cover - Icom IC-730 Instruction Manual

B. (SPLIT) Selects "B" VFO for receive and "A" VFO
for transmit.
23. TUNING RATE SWITCHES
The small vernier marks on the tuning knob are changed to
correspond to 10Hz, 1OOHz or.1K Hz steps which is selected
by pushing the switch either 10Hz, 100Hz or 1K Hz.
24. DI AL LOCK SWITCH
After the I C-730 is set to a certain frequency for rag
chewing, mobile 'Operation, etc., push the DIAL LOCK
switch the VFO is electronically locked at the displayed
frequency, thus inactivating he operation of the tuning
knob. To change frequency, the dial lock must first be
disengaged by pushing and releasing the D I AL LOCK switch
again.
25. R IT SWITCH
Switches the R IT circuit ON and OF F.
26. R IT CONTROL
Shifts the receive frequency ±800Hz either side of the trans-
4 - 2 CONTROLS UNDER THE ACCESS COVER
30. SPEECH PROCESSOR SWITCH
Switches the speech processor circuit ON and OFF. This
circuit enables greater talk power and better results in DX
operation.
31. SWR SWITCH
When measuring SWR, calibration SET and SWR reading
f unctions are selected with this switch. When reading SWR
make sure the METER switch on the front panel is in the
mit frequency. When the RIT is ON, the RIT INDICATOR
is illuminated. Rotating the control to the (+) side raises
the receive frequency, and rotating to the (-) side lowers
the receive frequency. The f requency shift by tuning the
RIT Control is not indicated on the frequency display.
27. R IT INDICATOR
Illuminates when RIT is turned ON.
28. BAND SWITCH
The BAND SWITCH is an 11 position rotary switch used for
selecting one of the 5 00KHz segments. The selectable bands
are 3.5KHz, 7MHz, 10MHz, 14MHz, 18MHz, 21MHz,
24MHz and 28MHz. (28MHz band is separated to four
500KHz segments.)
29. PASS-BAND SHI FT (TUNING) CONTROL
Allows continuous shifting of the pass-band from upper or
lower side i n SSB and ON. This will reduce interference by
a nearby signal. When the optional crystal filter F L-30 is
installed, this control allows continuous tuning of the pass-
band selectivity by moving the filter up to 800Hz from the
upper or lower side in SSB and CW. Not only improves
selectivity, but also can improve the audio tone. Normal
position is in the center position and is 2.4K Hz wide in
SSB.
RF position.
32. SWR SET CONTROL
This control calibrates the meter needle to the SWR SET
position when you want to determine the value of SWR.
The METER switch must be in the RF position and the set
must be transmitting a carrier.
