You should be able to hear everything you want to hear with the 7600GR.
You say you're in a city, and it sounds like you live in a large
apartment building. If so, your problems with reception probably stem
from the many sources of interference in your apartment, as well as
your neighbors'. Steel used in the construction of your building might
also be a problem. I suggest that you find a way to get an antenna,
even if it's just a length of wire, outside your apartment. If you have
a balcony of some kind, that would be a big help, but even dangling a
wire outside a window will be progress.
