Those additional sounds are well known, they are there since the beginning.
I've always thought they are just markers. And very likely they are.
BTW the T reminds me of some ships![]()
Let's assume three T, three T-ships. Perhaps a nice test with all the T-ships close to a UA could be a thing. No snakes this time.
But I cannot do it all by myself and my two accounts.
... Very early on I used to get these mixed up with what those who had identified what we now know as the Morse, and I thought they were just markers too.
However, what if they're not, and actually represent another 'layer' of Morse - 'TTT' would make sense, given its established use.
These aren't the only high-pitched warbles to appear outside the usual honk sequence, there might be more to this.
I like it!
