seen it on the internet also (but I don't see it now) =20

I have made lots of mods to the rig and some really improve the rig - oth=
ers are a lot of work for not that much benefit (I did the tracking sidet=
one mod and its nice, but I wouldn't do it again and I work lots of CW - =
I am considering doing the audio mod discussed here recently but haven't =
done it yey - I really would like for the tuner to work on all freqs thou=

I don't have my 765 on line anymore but I sure don't remember needing to
make any mods to the tuner.   I removed the diode on the board behind the
display - I think that is where it was - and operated on MARS for several
years before I quit the group. (Lots of nets to check in with nothing to
say and no messages to pass....)

I wonder where you read that info on needing to mod the tuner??   I
really don't think it is right.
