[ARC5] 500 KHZ Emergency Frequency

Some years ago I was in England doing a month long "school" trip on some of 
Marconi's newer gear.  I did a lot of listening in the tiny "inn" room I was 
in with an old Grundig "Satellit" receiver with an add-on BFO.  I couod hear 
scads of the European stations on 500 and very frequently WCC, WSL in late 
evening 2300-0200GMT.   All those power houses are QRT now!

>From the New Orleans area back home, It was easy to hear the west coast MF 
stuff very late at night, wee hours of morning local time (cst)  Mostly KLB, 
KFS.

I really miss those days when 600 meters was very active.  Also the huge 
amount of HF activity as well that is gone now.....end  of  a golden era of 
radio communication on Morse.  It will probably never return to that "glory 
era" again for any reason.

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.
