Thanks for the image with the notes. This is what I wanted to do:
I deleted the numbers after the decimal point in the coordinates for your protection and increased the height to make the CH22 green line easier to see.
You ARE on the CH22 fringe, but a -3.9 NM can be compensated for by antenna gain. The biggest problem is interference from strong local signals. The FB/FR ratios of the antenna can attenuate the strong locals to some extent, but there will still be reflections from the strong locals off objects in front of the CH22 antenna.
The terrain causes a lot of interference to the signal.
