The Chinese are not anti Radio are they, if so why can't a group of Chinese hams go and activate it,
Well, ask one next time you work them on the air. Maybe they'll tell you.
My guess is simple: Politics. Most of all of the various rocks in the South China Sea are, to a greater or lesser extent, under the control of the Chinese military. Many are being built up into larger artificial islands. Or, so say news reports I blunder into once in a while.
China very much wants to claim some sort of control / sovereign status / something over the whole thing, including Spratly but definitely everything else.
I don't personally regard China as a Western-style hegemon power. They never really have been throughout history.
But, those things that it regards as China, such as the South China Sea, it can be that way. It is also pretty aggressive about it.
Which means we can go whistle for this stuff for a while.
I hope you're right. I hope some Chinese hams can thread the needle and activate these places, even during this, shall we say, muscular period in the South China Sea.
But, like YV0, I am not holding my breath.
