Perhaps orient the radio to put the 1630khz station in the null of the internal
antenna. That would attenuate the signal, much as the ATT button does, but not
affect WGN. If you have trouble finding the null, tune off freq. slightly from
1630khz and try it there.

They are probably so darn loud by you that it's overloading the radio.
