There have been a couple of older attempts to attach sound to the mines. TheDarkWraith (TDW), aka: Racerboy, publicly attempted it most recently, and eventually gave up on the idea. That was years ago. The problem with the approach is that it would have each mine emitting sonar sound, which is a bit much for the computer, AND for the player to handle. Imagine those things - hundreds of them in a minefield - making their sound constantly, and "hearable" out to 40km or more... not good. I had an idea to have one mine, not part of a regular minefield, be the sound emitter, and then placed near the minefields, but trying to limit that to only the FM device being capable of picking them up would be a bit difficult... It would be nice to know if the original devs had any idea of how they were going to implement the FM sonar, because there is a skeleton for that in the game already... alas, no documentation of such.
