Alonso's outbursts at Suzuka, in which he compared Honda's "embarrassing" power unit to a "GP2 engine", triggered theories the Spaniard was trying to deliberately breach his McLaren contract.
But he says he was just frustrated.
"What you say on the radio should remain private," Alonso argued at Sochi, "because you are talking with your team not publically. I think publically we have been very, very positive all the time.
"I think this is a very unique sport, that we have a microphone in our helmet and it goes live on television. Imagine (it) in NBA or football or something like that.
"I'm happy it was only broadcast in Suzuka because if you hear all the radio messages from me or from Jenson (Button) or whoever, you will be even more surprised," added Alonso.
The Finn, however, does not support the idea of a ban.
"It is known to all of us that some of the radio can be published. So it's up to us to decide what we say or not. If you want to keep something private, you can easily do that.
"It's no secret that certain messages are displayed and I think that is much more interesting for the fans than otherwise."
But Raikkonen insisted: "There are many differences between Sochi and Singapore."
