I mostly use my Sony ICF-2010 for swling.

Many times on 75 meters, I hear out of tune signals or voices. So, I
then turn the radio to LSB or USB. And then the audio of my radio goes
down. But the signal strength is still high or strong.

I know their Hams operators talking. But the bigger problem I have is
that when I go LSB or USB to better hear them, I lose almost all of the
audio. Even if I bring the volume all the way up. I don't understand this.

If the Hams operators are in plain old fashion AM then everything is
cool. Just like now I am hearing 3881.0 khz, 2:27 UTC.

I really don't see the point of side band transmissions, if everyone is
going to have a problem tuning in. -One voice talking too high and the
other is too low. Maybe their is something more to this. I don't get it.

The scary thing about bring the volume all the way up for a weak audio
is, if all of the sudden I decide to press the wide or narrow button,
the volume level will be too loudly, this could hurt the speaker. So as
a safety practice, I always bring down the volume level even before
turning to radio off. That why I prefer turning knobs, not sliding
buttons. -(You hear that Coby!) LOL!

Now what's funny is, on my Cobra 148-GTL, when I turn to LSB or USB, the
signal gets a lot stronger. Where as with my Sony ICF-2010 it's the
opposite.

Also my sony has a Sync button, when I press that, the audio gets low
too as well. Why?

Another thing that I notice in other radios: Their is no LSB or USB just
SSB. I do not understand how that works or which is greater to have.

Also, in my Panasonic RF-2200, their is a BFO button. It seems to work
for turning up Ham operators and CW signals. -Although you have to tune
a bit up or down. (I love the sounds of radio squeals). But when I pick
up a regular SW broadcast, I see no other use for the BFO button.

I would like to know: When, how and why did SSB and BFO came about?

Is their a device that I could connect to the audio speaker hole to
better clarify the audio?

And what are those beat buttons that sometimes you see on the side of a
radio.

This afternoon, I bought MT mag, I hope that in the future they could
explain some of these things in 'Beginner's Corner'.

73, SR!
