The right preposition with a Radio Station.

[Basmamostafa]

Hello everyone,

Which of the two prepositions is right?

I want to be a presenter on Nile FM.

I want to be a presenter at Nile FM.

I have a strong feeling it's the first one. I just want to make sure. Any other suggestions??

Thanks a lot.

Both sound right to me.

They are very close. I'd use #1, but I'm not sure why. #1 has just a bit more sense that you would like to have your voice on that station. #2 just a bit more of a sense that you would like to work at their studio building. If it was a situation where you sent in your speech from a remote location, I'd use #1 for sure. [American usage]
