Oops Captain, that's the tone switch.
Check the ATT-switch!
Or adjust the attenuation wheel (minimum).
You find both of them on the left-hand side of your 7600GR.

I've checked and rechecked all the controls
and everything seems to be working correctly, but SW signal
sensitivity is weak. Also, there is an annoying background hum,
especially when I listen to a strong station, like EWTN.

Rechecking the AM mode or trying a different one might help.

The 7600G[R] is a small radio and so has a small internal loop. Its
AM reception can be vastly improved by putting it next to a MW loop
(like the Terk loop). It's not bad, but it can be improved, as can
even the vaunted 2010 by a MW loop.

But the selectivity of the 7600GR, and the ability to use a sideband
to get away from adjacent channel interference, make it better for
DX than even the large good radios like the GE Superradios, once you
add the loop.

It's also improved if you don't have the attenuation switch on. WJR
ought to sound like a local on every radio.

(The 2010 is even better because its synch detection is quieter and
works discreetly on weak signals.)
