AM/FM tuner, cannot get AM stations?

[Robert Blass]

I have this AM/FM tuner, bought about 10 years ago. I tried connecting
an AM antenna to it. All it does is make a LOUD humming noise. Is
there some configuration I need to make the AM side of the antenna
work properly?

It has [3] places to put wire that attaches to your antenna. The FM
antenna is just simply placing ONE wire into the hole and clamping it
down.

I have a few choices like 1&2 or 1&3 or 2&3 etc.....

They all clamp down so no need to connect with screws.

The manual, if I can find it, I remember it as being impossible to
understand...It said something like 'attach your antenna and
enjoy"...no details...

So what is the deal here?
thanks

Polarity doesn't matter, so you only have three permutations to go through.

If you can't get _any_ stations, and you're not helplessly out in the
boonies, then the AM section of your tuner is shot and needs repair (or
pitch and replace).

Do you need to implement control loops in software?
"Applied Control Theory for Embedded Systems" gives you just what it says.

That, or there is so much electrical noise that it wipes out the
entire AM band.

Another possibility is that he is inside a metal building that blocks
all the AM signals.

Probably the wrong type of antenna? Your FM antenna (circa 100 MHz)
is a folded dipole, and the AM antenna (circa 1 MHz) is a loop
type (five or ten turns of wire , 6 inch diameter).

Of course, it could also be a bad selector switch; give all the
switches a thorough workout, and try contact cleaner.
