For me a radio is a box with the knob to rotate.
Now at FM no brakes between stations. At AM are.

The battleship HMS Formidable is sunk off Lyme Regis, Dorset, England, by
a German U-Boat.

An earthquake (6.8 in Richter scale) in Avezzano, Italy, kills more than 29,000.

The 1915 locust plague breaks out in Palestine; it continues until October.

The theory of general relativity is formulated.

The first prototype tank is tested for the British Army for the first time.
