Yes. Propagation on 600 meters is very odd: at times, one could hear signals from all over 
the entire Pacific Ocean. One of the members of our 600 meter forum who lives here in the 
U.S. has copied 500 KHz signals from ships in the Med.

Most are in Africa, as I remember it.

A BC-453 or an R-23/ARC-5 is an excellent 600 meter receiver. I use one here for that.
