Topband: The "new" Topband

[Radio KH6O]

Colleagues,

Have any of you attempted to get on the 630 meter band?

As a US Coast Guard radioman in the 1970s, 500 kHz was the worldwide
maritime CW calling frequency; almost all night-time traffic occurred
on 600 meters. While stationed at Coast Guard Radio Honolulu (NMO),
I'd copy stations Pacific-wide -- from Alaska to Australia, from the
US west coast to Asia. Just incredible coverage sunset to sunrise.

(Daytime traffic shifted to the 6, 8, 12, 16, 22 and 26 MHz maritime bands.)

73,
Jeff KH6O
