Convenient functions for transmit

About 5 MHz band operation (USA version only)

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 (Effective Radiated Power)

• 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.

• 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.

• 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.
