Thats great that Iran has ham radio. We're all here on the planet and we might as well communicate as we become more alike and hopefully all head into a peaceful, fun and prosperous future together.
Electronics buffs, and really everybody in the sciences, all around the world, and I suspect, we'll find in the future, even from different stars and different species, all speak the same language!
Maybe you've seen it, I hope so, (this film always makes me cry, for some reason) the movie Contact starts out with Jodie Foster as a young girl, using her ham radio- Then later on in the film - they first establish hyperdimensional communications with another intelligence, light years away, and they start building up a common language via math?
Ham radio is in a sense, like that.
