Here are two reports that will give you a lot of international AM
broadcast reception information relevant to eastern USA and Canada.
(Prince Edward Island DXpedition)
(Cape Cod, MA)
Note that, unlike a lot of stuff out there on the web, these are based
on RECENT receptions.
Old reports invariably list a lot of no-longer-active stations such as
former blowtorches Norway 1314, Sweden 1179, Switzerland 765, et al.
Though 160m may not be as fussy, the observation of these AM BC signals
indicate that strengths drop like a rock as you travel inland.
Smelling salt air and hearing seagulls seems a near prerequisite to
strong DX signals below 1.7 MHz.
