Boston's pretty easily to get during the day.
New York is easy to hear at night. As early as 4pm in the winter.
Chicago's pretty good at night too.
I have - when weather was good and I played around with my best AM receiver - gotten as far as LA.
Interesting that the receiver I’m talking about is an old portable b&w TV designed to run on batteries! One of those 5 dollar garage sale deals!
TV is worthless now since digital, but the most sensitive AM setup I’ve ever seen. If I was more ambitious, I’d yank it out, build a cabinet and toss in a power supply. Maybe in like 2315 when I don’t have nuthin else to do!
