Most of the construction appears complete at the Etna site so I decided to check on the FCC database and see if they were using radios at these places. I found two licenses, one for each site.
WQXM524 - Obetz (aka CMH-2) - (ULS License - Industrial/Business Pool, Conventional License - WQXM524 - AMAZON.COM - CMH2)
WQXM763 - Etna (aka CMH-1) - (ULS License - Industrial/Business Pool, Conventional License - WQXM763 - Amazon.Com-CMH1)
Looks like an 8 frequency system with emission designation of 7K60FXE.
