Dyson Sphere under construction?

BTW, turning around the perspective;

to an observer far away from our solar system, there is something apparent about here that would also be very unusual.  The radio brightness for a distant observer would be astonishingly high, and quite variable.  And the variability would have 24 hour and 365 day cycles.  Our otherwise ordinary G type star would be 'uniquely' anomalous.

Human civilization on earth radiates an enormous amount of radio waves.  To a distant observer, it would all be melded together, no individual source (like my garage door opener) would be discernable.  And we radiate at those wavelengths more than the sun does.

And at 50 light years it would possibly be indistinguishable from ordinary noise according to discussion I've read.
