Default FT-757 GXII alignment....

the full ervice manual is on mod.dk site
the power variable on the front panel always was 'iffy' though a squirt of
cleaner (not WD40) might help.
dont forget as the other gent says, the SWR pot on the back will effect the
meter PO scale.
also it is caled into 50R so will not read correct of an aerial or ATU. as
such.

if you wish help
pse ask

done loads and own one since 1985

Has anyone any info on servicing one of these?

The power control is out of alignment (about 3/4 of the way up it suddenly
jumps into TX at full power, with it being very sensitive to get any
control between full and no power).

Possibly a bias problem on the PA?

And the power meter needs re-aligning.

And the FM deviation is too high.

Can anyone point me towards the internal pots?


Thanks,
