If no one would ever really be using this mode/frequency to communicate long distances given this was such a special circumstance, and HF is already the standard (I understand), what practical has been achieved? What is this for?
Second, practical research into how to transmit information more efficiently has many, many applications. WiFi and mobile-phone technologies would not exist without research like this. [2]
It's fun to do something that nobody has done before. Even though I don't care about the actual goal, it's interesting to read about what the obstacles are, and how people overcame them.
But equally, if someone is sensitive about being asked what's it good for, then maybe don't seek worldwide attention for it on the front page and get offended when the world asks you such questions.
Also I don’t see any reply that I thought demonstrated “offense”. Perhaps it was deleted.
It's boring to meta-debate the quality of discussion / people's voting on a story or comment, so I won't pursue it much more here. But if something doesn't have a known practical value then let's talk about what its value is, or could be. Don't just vote someone down because you're offended that your pursuit / hobby was questioned.
This feels like its a "street car mods", "CPU overclocking", or even "distance running" kind of hobby. Part ego, part technical, part seeing how far you can push something. Sometimes these things have use (to you, or others), sometimes not.
