Driving to Darlinghurst from the north side of the harbour involves a trip through the Sydney Harbour Tunnel. This proves rather annoying when listening to favourite radio station FBI 94.5FM, which drops out a few metres under and the static takes over.

I recently discovered the existence of a sweet spot, about 800 metres into the 2.2 kilometre southbound journey. Sure it only lasts a second, but I always listen out for it now.
