DSpeech compressor

The IC-706MKIIG has a built-in, low distortion speech compressor circuit. This circuit increases your average talk power in SSB mode and is espe- cially useful for DX’ing when the receiving station is having difficulty copying your signal.

➀Select USB or LSB mode.

➁Select the ALC meter.

•Push [DISPLAY] 1 or 2 times to select M, if necessary.

•Push [MENU] one or more times to select M3, then push [(F-3)MET] one or more times to select “ALC.”

➂Select the mic gain display in quick set mode.

•Push [DISPLAY] for 2 sec.

•Push [MENU] one or more times to select Q2 MIC GAIN.

➃Adjust the mic gain.

•While transmitting at your normal voice level, the ALC meter should read at about the middle of the ALC zone.

•Be sure the mic gain is in the range of 2 to 5.

➄Select M4.

•Push [DISPLAY] 1 or 2 times to select M, if necessary.

•Push [MENU] one or more times to select M4.

➅Push [(F-2)COM], then adjust [COMP GAIN] so that the ALC meter reads within the ALC zone whether you speak softly or loudly.

Note: When the ALC meter peaks above the ALC zone, your transmitted voice may be distorted.

DVOX operation

The VOX (Voice-operated Transmission) function toggles between transmit and receive with your voice. This function provides an opportunity to input log entries into your computer, etc., while operating.

➀Select M4, then turn the VOX function ON.

• Push [DISPLAY] 1 or 2 times when S or G appears.

 

• Push [MENU] one or more times to select M4.

 

• Push [(F-1)VOX] to turn the function ON.

 

➁Select VOX GAIN in quick set mode.

 

• Push [DISPLAY] for 2 sec. then push [MENU] one or

[MENU] [(F-1)VOX]

more times to select Q4.

 

➂While speaking into the microphone, adjust [VOX GAIN] until the transceiver is transmitting.

➃Select VOX DELAY in quick set mode.

•Push [MENU] one or more times to select Q3.

➄While speaking into the microphone, adjust [VOX DELAY] as desired.

➅Select ANTI VOX in quick set mode.

•Push [MENU] one or more times to select Q5.

➆If the receive audio from the speaker toggles the transceiver to transmit during receive, adjust the [ANTI-VOX] to the point where it has no effect.

➇Push [DISPLAY] to exit quick set mode.
