TL;DR
The Računalniški muzej (Computer Museum) in Slovenia is celebrating the 55th anniversary of Radio Študent by broadcasting a ZX Spectrum game called "Kontrabant 2" over FM radio. This nostalgic event allows owners of the original ZX Spectrum to load and play the game via radio waves, reminiscent of how games were distributed in the past. The broadcast will take place at 89.3 MHz around 21:30.
