IC-746 FAQ
Page:27 Only one bar for CW sidetone level, not two
In the CW -> KEY -> SET menu, there are 2 options that control the CW sidetone: options 1
and 2. Option 1 sets the sidetone level via the displayed bar. However, option 2 is only an
ON/OFF setting; there is no level bar (contrary to what the manual shows).
Page:32 No ALC adjustment for FM
In "FM Operation", under TRANSMITTING, section 5 it states: Push TRANSMIT...and
adjust the MIC GAIN so that the ALC level in the ALC meter stays in the ALC zone when
speaking into the microphone.
The ALC meter is maxed out on any setting of the mike gain and has no meaning or effect
under FM.
ALC adjustments made in SSB carry over modes. Once you get the audio drive level
adjusted for proper SSB modulation, then the audio drive level ends up being right for all the
other modes as well.
Page:33 Incorrect filter diagram
The diagram at the top of the page is incorrect. It shows only one stock filter (2.4 Khz wide)
at the 9Mhz IF. There is a second, 15Khz wide, filter at that point instead of the direct
"through" connection shown.
Page:42 Incorrect Page Reference
Reference for Noise reduction p.39, should be p.40
### 15Khz filter at 9Mhz IF?
Page:46 No ALC adjustment for either AM or FM
In the "Speech compressor" section, the ALC meter doesn't appear to work on AM.
ALC adjustments made in SSB seem to carry over to other modes. Once you get the audio
drive level adjusted for proper SSB modulation, then the audio drive level ends up being
right for all the other modes as well.
Page:46 Speech compressor
The "Speech compressor" instructions fail to make clear the fact that both the MIC GAIN
and COMP GAIN controls will have to be adjusted for proper operation.
