Site/Tower Google Map
(NOT UPDATED) This may prove I have too much time on my hands, but I have taken all of the information from the CARMA profile and plotted all the transmit sites for StarCom using the "my maps" feature of Google Maps. Anyone wanting to check it out can go here: Link
A few things about the map:
- After plugging in the coordinates for each site on the map I tried to locate the exact tower or structure used by a combination of satellite view, street view, and in some cases switching to Microsoft's Bing Maps for their Birds Eye view. If it still wasn't exactly clear I made a guess usually just putting the mark where the lat/lon coordinates landed me.
- Pushpins are used for single site locations, blue for the north zone, green for central, and purple for south.
- The "balloon" type pins are used on all simulcast sites, with different colors for each site.
- At this time I included the county owned sites that use the same technology as StarCom including McHenry County (all of these being co-located with StarCom sites), Champaign's MDICE, and the St. Clair County system. My only regret doing this is that with all these sites included Google shows two separate pages for the sites, so not all of them are visible at one time on the map. I'm debating whether to take these sites out and make the map strictly StarCom so all the sites show up at once.
Google allows anyone with a Google account to make changes to the map, however I have it set up to only allow those that I invite to make the changes. If anyone is interested in helping to maintain the map or make corrections or additions to it, send me your e-mail address and I will add your name to the list. If you notice any errors either in locations of towers or the control channels listed and don't have a Google account or don't want to mess with the map, e-mail me and I will be glad to make the corrections.
Comments, praise, and even criticisms are welcome. -Mike McGowan - K9JPM
New StarCom21 tower map (Click here) - The above map has become outdated; I've attempted to reach the map owner to offer help to update the map, have not gotten a response. I have created a map that display updated and current tower locations for 8 digital systems within the state. Last update to the map for each system is in the description of the map. If you have any questions, comments, concerns please feel free to contact me. Enjoy! - Isaiah (Mex)
