As an additional thought, what I did when I got the radio was to swap
out the stock 6 kHz filter for a better aftermarket one that had
better skirt selectivity. The original is just a bit broad at 60 dB
down. Cleaned things up quite nicely.

Kenwood had an improved 6 Hz filter available right from the start (YK88A1)
and many buyers of the receiver upgraded to this filter at the time of
purchase. My 'stock' (poor) 6KHz am filter still sits in the box that the
good YK88A1 came packaged in. I don't know why I save it as it was awful.
