i based my concept on the station number 100.9, i drew them uniquely for you using just a Square and the golden ration proportions
this allowed me to make a logo that is incredibly visible also at the smallest size, you can see this by zooming out if you are on a web browser (ctrl + scroll back with the mouse)
the I has a triangle pointing to the top, as a tranding symbol
please let me know if there is anything i can do to emprove it
