D D Convenient functions for transmit
• Speech compressor (p. 6-5)
➥ 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.
• VOX (voice operated transmit) (p. 6-2)
➥ Push [VOX/BK-IN] to turn the VOX function ON
and OFF.
• "VOX" appears when the VOX function is ON.

rules specified by the FCC, transmission is illegal on
any 5 MHz band frequency other than the 5 fre-
quencies indicated in the table above.

RECEIVE AND TRANSMIT
• Transmit quality monitor (p. 6-4)
➥ Push [MONI] to turn the monitor function ON and
OFF.
• Rotate [MONI GAIN] to adjust the monitor gain.
• Monitor indicator (above [MONI] switch) lights when
the monitor function is ON.
• Audio tone control (p. 12-4)
➥ Push [F-7•SET] then [F-1•LEVEL] to enter level
set mode. Select an item with [F-1•Y]/[F-2•Z]
then rotate the main 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's your responsibility to set all controls so that trans-
mission 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 memory
channels for easy recall.
*The FCC specifies center frequencies on the
5 MHz band. However, the IC-7800 displays carri-
er frequency. Therefore, tune the transceiver to
1.5 kHz below the specified FCC channel center
frequency.
