Hi Dick -
I haven't run into that specific problem, but the carrier suppression is
a function of U303 on the Transmit/Exciter board. Absent any further
information from one of the TR-7 experts, I'd start by pulling C320 and
replacing it.

Drakelist de PA2DW,
As this list houses a lot of specialists, I call for help:
My TR7 suddenly seems to have developed a poor carrier-suppression. I
dont know when this started however, as I barely use SSB.
I can tweak the carrier-potmeter to a minimum, but still there is a
LOT of carrier...
Now before I start to measure around (which is hard in this area of
the TR7 without extenderboards...) I would like to know if this is a
known problem, so I can go straight to the part concerned :)
