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.

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.
