14.9.2024 new final coordinates, hint and spoiler. Just enter the puzzle solution into the Certitude again.
The cache is not hidden at the posted coordinates and it is not necessary to visit the place to get the final coordinates. However, you can see there the beautiful old bridge Kamara ston Avlaka (Arch to Avlakas) over the river Platis.

The arch of this bridge reminded us of the induction coil and the young years at the Alma Mater ;)
How to find the final coordinates
Look at the scheme and calculate the value of Variable. When thinking about what the Variable represents, you can enrich yourself by listening to music on the radio.

When calculating, consider what order of Variable you need. Enter the resulting value rounded to one decimal place (i.e. in “xx.x” format) into the Certitude checker. This will give you the final coordinates and a hint.
Just in case, a local cacher will provide maintenance assistance.
