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.

Select USB or LSB mode.

Select 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.”

Select the mic gain display in quick set mode.

Push [DISPLAY] for 2 sec.

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

Adjust 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.

Select M4.

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

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

Push [(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.
