What radio do you have?

I have a Grundig S350.

I am starting to think that what I am asing is a little too much.

I had a YB400PE and it had a SSB switch and all it did was apply some
function on on my AM signal.

I have many audio applications but I am looking for a means of
filtering the band and applying the missing carrier (or whatever other
sgnal manipulation.)

Basically, I want the warble on any given station to be cleared up.

Thanks ;-)

It's really easiest to just get another SSB radio. But you could build
a BFO circuit I suppose. Back when I first started out, I used to use
old clock radios as tunable BFO's. You just stuck the old BC radio
right next to the SW portable, and tune it "the BC radio" until you
hear a "swish" sound in the SW radio. Tune the BC radio until that BFO
signal is sitting on your SW freq. If you are careful in tuning with
both radios, it's a workable setup. But if either radio drifts, you
need to touch up the tuning a good bit. The "SSB" switch on the 400PE
was a built in BFO circuit. MK

This is a pix of my first SWL setup when I was in 8th grade. Note the
philco portable with the AM clock radio directly behind it. That was
my "BFO". The one to the left, would work also, but I used it as my
actual clock, and for AM-BC. The contraption in the center view is my
first 40m "7 mhz" transmitter I built using a 6V6. It actually worked!
No smoke was ever let out of that unit...That pic was taken in 1971.
Hard to believe that was 33 years ago...Proof of impending old
fartism... I can say, my receiving devices have improved a bit since
then.... That philco was eventually stolen out of my locker at
school the next year or so...I bought it new at a firestone tire store
of all places. They sold philco TV's , radios' , etc back in those
days..MK
