I have a picture of one of the 46 MHz repeater towers. Below the antenna, I see another directional antenna pointing towards the main maintenance building towards the other side of Hwy 41. Perhaps a repeater link? Not sure. Took this picture while camping with the family.
TAFL shows three low-band channels as simplex. No UHF is listed at Bon Echo but that is obviously a UHF yagi. TAFL shows a number of MNR link channels in the 410-420 range, hard to pin down which of those it could be. CloseCall to the rescue...
Direction that the yagi is pointed could be a clue.
I can hear comms on 46.670 , clean up, firewood, the usual. The picture I took is at the entrance to Hardwood Hills campground section of Bon Echo, 4.5 km north west of Hwy 41.
