Hi Stacey and all,
  well since the first of the year I have about 165meg of raw and about 125
meg of tlm that I have personally collected so I know what has been turned
on recently, Rudak has and it has been reloaded so its up now.... by leaving
the question open in my original email I was trying to give the people who
are in the know the opportunity to explain what we the users are seeing...
when I originally asked about the warble I was told it was radar...

I think most would agree it isn't...

 And I still would like to understand why Rudak causes this.. I would also
like to understand what happened to the 6db drop on L2.

But since detailed info on how AO40 works is very scarce, (mostly all you
can find is big picture theory of ops...) we the users have to turn to the
designers or command stations for info...

and getting info seems to be harder than pulling teeth...

I thought this was forum to learn in?

I might remind everyone of AMSAT-NA's bylaws...

A. Developing and providing satellite and related equipment and technology
used or useful for amateur radio communication and to conduct experiments by
suitably equipped amateur radio stations throughout the world on a
non-discriminatory basis.

B. Encouraging development of skills and the advancement of specialized
knowledge in the art and practice of amateur radio communications and space
science

F. Disseminating scientific and technical information derived from such
communications and experimentation, and encouraging publication of such
information in treatises, theses, publications, technical journals and other
public means

Seems  AMSAT-NA's mission to advance amateur radio skills and knowledge..

So I don't think I'm outta line asking about this subject.... if the
builders and designers don't understand it, fine say so...  if this problem
is understood then please explain it...

If the problem is understood but no one wants to tell the users, then its
time AMSAT rewrites its bylaws...

Thanks
73's
