Hi
My first post in this group!
     I am interested if the testing, which can be done easyly
by astronomers, has ever been done the way I will describe
it below, or not.

<snip, looking for change in detected frequency based on Earth's
motion>

This will not establish a value for c.  You would have to assume that
Maxwell was correct, and the "ballistic photon" folks do not assume
that.
At this point I am interested only to find out
if the lightspeed was really
found experimentally constant, using cosmic sources of radiation,
and of course to learn where this information
was published and accessible for the public.

You could use the Moon as a shutter, and if the CMBR or other high-z
source that should be occulted by the Moon is not occulted at a
similar time as local visible light objects, then you will have
detected an anisotropy.  The 1.3 second one-way transit time can be
multiplied by a (1+z) of almost 5 for some objects, and more than 1000
for the CMBR.

Might even get to publish a fancy paper or two on the subject.

Thanks for the tip!
I am not really interested in publishing now.
I just got this challenge for myself, to understand how things are
with special relativity theory and the basics of EM theory.
I do not reject anything from the start and I not accept anything
as real physics without experimental facts.
Even the experimental facts are subject to interpretation.
For example, I can imagine easily an alternative interpretation
to time-dilation found for the case of muons.:-)
