Just learned today that KSM is a newly licensed maritime CW station, "like the old days." Listened to it for several hours today with its guard tape, weather, and even one call for a ship station. Visit this link to learn about this revival of maritime history. http://www.radiomarine.org/ksm-proj.html
Very interesting to anyone interested in maritime CW.
I've spent a couple of years listening to the PEMEX maritime CW net on 3700 khz but it seems to have disappeared since the expansion of the US 80 meter phone bands. Though it is in Spanish, it is an active CW maritime net.
Maybe KSM will bring back some of that to the HF airwaves as well!
