The SSB signal has width to it and is typically 3 khz wide. For an LSB
signal 2 khz above you, that means his signal has pieces that go as far as 1
khz below you and up to 2 khz above you. So there is an overlap of his
signal and the JA. The only thing filtering will do is reduce his signal so
you only hear the portion that is 500 hertz wide that overlaps your filter
width.
