D Convenient Functions For Transmit; D About 5 Mhz Band Operation (Usa Version Only) - Icom IC-756PROIII Instruction Manual

D Convenient functions for transmit

• Speech compressor (p. 68)
➥ Push [COMP] to turn the speech compressor ON
and OFF.
• Pushing [COMP] for 1 sec. to select the compression
bandwidth from wide, middle and narrow.
• Transmit quality monitor (p. 70)
➥ Push [MONITOR] to turn the monitor function ON
and OFF.
• Monitor indicator (in [MONITOR] switch) lights when
the monitor function is set to ON.
➥ Push [EXIT/SET] for 1 sec. then [(F-1)LEVEL] to
enter level set mode. Select the monitor level item
with [(F-1)Y Y ]/[(F-2)Z Z ] then rotate the tuning dial
to adjust the monitor gain.

To assist you in operating the 5 MHz band correctly
within the rules specified by the FCC, transmission
is impossible on any 5 MHz band frequency other
than the 5 frequencies indicated in the table above.

RECEIVE AND TRANSMIT
• VOX (voice operated transmit) (p. 66)
➥ Push [VOX] to turn the VOX function ON and
OFF.
• "VOX ON" appears when the VOX function is set to
ON.
• Audio tone control (p. 95)
➥ Push [EXIT/SET] for 1 sec. then [(F-1)LEVEL] to
enter level set mode. Select an item with [(F-
1)Y Y ]/[(F-2)Z Z ] then rotate the tuning dial to adjust
the audio tone.
Operation on the 5 MHz band is allowed on 5 discrete
frequencies and must adhere to the following:
• USB mode
• Maximum of 50 watts ERP
• 2.8 kHz bandwidth
It is the operator's responsibility to set all controls so
that the transmission in this band meets the stringent
conditions under which we may use these frequencies.
NOTE: We recommend that you store these fre-
quencies, mode and filter settings into the memory
channel for easy recall.
*The channel center frequencies that are specified
by the FCC, show the center frequency of their
passband. However, the IC-756PROIII displays
carrier point frequency, so set 1.5 kHz below from
FCC channel center frequency.
