I bought a used Grundig Yacht Boy 400 a few weeks ago. The Sony ICF-SW1 that
I have picks up stations about as good as the YB 400. However, my YB 400 has
much worse sound quality than the SW1.

I don't have a Sony ICF-SW1, but I have
an 8 year old Grundig YB-400.
It exhibits none of the symptoms you describe.
Sounds good, works good.
