Map Index

Maps, maps, have we ever got maps!  This page is the index to all the maps posted on the site.  Many of the site's other pages also contain maps or context-related links to maps, but this is the unified listing.

Note: Because they contain small print some of these images have been sized to fill a 1024 x 768 screen.  See the Photo Viewing Tips page for information which will help assure that you are able to view images on this site at their full size.

Cities with Stations: The little Marine Radiotelephone Service pamphlets produced by AT&T contained maps that showed the city locations of the stations.  Taken together these maps show some of the changes in the operational status of the stations serving the US including those serving the lakes and rivers.  There are both MF/HF and VHF maps covering the period from the late 1950s to the early 1980s as follows:

    MF/HF:    1947-8 ~   Late 1950's    1966   1968   1971    1971-2 *   1974 #   1976 #   1981 

    VHF-FM:       1968   1974    1976    1981

Known errors on the AT&T MF/HF maps are: 

    WAY - Chicago should be included on all of the Mississippi Valley frequency lists.

    ~ The Pittsburgh station shown on this map was licensed but not on the air.

    * The ownership for WBL on this map should be (11) rather than (4).

    # WAY - Chicago should be included on this map as a Bell System station.

VHF-FM Networks:  Several of the stations (or successors) operated multi-station remotely-controlled VHF-FM networks.  Here are maps of some of those networks:

                        WFN/Watercom    WGK    WJG    WLC Early    WLC Late    WMI

Station Locations:  The exact locations for the stations with links below are known, and the MS Streets and Trips program has been used to generate maps showing the station location(s) in more detail:

                        WAD    WAS    WAY    WBL    WCM-P   WCM-C    WFN    WGK    WJG    WLC    WMI  

Canadian Stations:  Here's a 1950 Map of the Canadian Great Lakes Stations, and here is a link to the (Off-Site) Canadian MTCS  Maps page displaying coverage maps for the present network of VHF-FM stations.

(Can you contribute additional maps?  --  or exact location information for WGK?)
