Anyone out there have any mods for the Swan 240. I just got one and
there had been a small slide switch and a
resistor added to pin 9 of the 6U8 carrier osc. I'm wondering what this
mod is for.

Hi,

That Swan 240 modification is described on page 29
of the manual. It disables the BFO during receive,
for improved reception of a.m.

There also should be a switch section in the cathode of V12A,
the product detector, with the addition of a 10K resistor
and 2uF electrolytic there.
