I think you have it........the LUK spot with the 4 antenna towers is probably your best bet. They have that classic FAA radio look, and the sheer number of antennas makes the case. There is enough there for Merwyn and Flight Service and probably approach control, too......
Some fine detective work, too!
Thanks! I found myself over in that area, didn't expect to be over there yesterday and didn't have a radio on me. Might try go get over there today if these storms let up.
It gets weirder though. I noticed that if you scroll down to the bottom of this page
you can see a little more detail on the RCAG sites. Here, they have it spelled Merwin. There is a "Merwin" on the map not far from me, but definitely not the LUK site. However each frequency is listed, with a sector and an area. The one in question (134.700) is listed as Batesville, IN, which is a good hour away. What I'm not sure of is if those different sectors are different transmitter locations, or different areas that the RCAG is intended to cover. Haha... this is interesting learning about for sure.
