[ICOM] 756Pro Alignment

[Adam Farson]

Hi Ken,

As other contributors have suggested, you should be able to correct the
error by following the master-oscillator calibration procedure on p. 76 of
the User Manual. No test equipment is required (other than a reasonably good
ear).

As the entire IF filtering and demodulation process is performed in the DSP,
there are no "BFO alignment" points in the classical sense. Once you have
done the frequency calibration, the radio should be spot on. As all the
local-oscillator sources are derived from the master oscillator, the
calibration will be accurate on all bands.

For further reading, you can download the service manual here:

Cheers for now, 73,

Subject: [ICOM] 756Pro Alinement


Hi all,

I have a 756Pro that seems to be out of alignment.  If I tune in 10.000mhz
on AM, then switch to USB then LSB, shouldn't the sound be the same on both
LSB and USB?  It is not.  I've checked at 10, 15, and 20mhz on the WWV freqs
and USB/LSB tone is off on all bands, but amount of tone off varies per
band.

I looked at the ICOM alignment procedure in the manual, but was told by a
couple of folks that would not do the alignment I needed.  Is this true?  OR
would this  procedure work?

I would like to find a repair should within a couple of hundred miles of
Mobile, AL so I could perhaps take the rig in one morning, and pick it up
that afternoon if at all possible.

Thanks for any info/help anyone can provide.
