The High Seas Stations

The emphasis of this site is on documenting the history of radio on the Great Lakes and inland rivers.  Though my original intent for this page was to provide only a listing of the high-seas stations and some links to more information about them on other sites I recently found (2013) that many of the external links were dead. Thanks to the Internet Archive I have recovered some of the missing pages and even added other information that has been long gone from the Internet. Additionally, several new external sites were added.  Please send corrections, additions, links etc.

NY Overseas switchboard in 1943
This 1943 photo shows the NYC AT&T overseas switchboard that also connected ship-to-shore
calls from WOO (and perhaps WOM) to the land-line telephone system. The ship-to-shore
switchboard is 106 (the 4th one from the left). At the very rear is a board showing the ships at sea.  
Clicking on the photo will show a very detailed version.
