Is the reason why Docs for the ELONICS E4000 are not published because it is
Chinese? If anyone has the Datasheets for the ELONICS E4000 and REALTECH
RTL2832, please share them to osmocom-sdr(a)lists.osmocom.org or post them to
http://sdr.osmocom.org/trac/wiki/Hardware
Thanks

Hi,

The E4K is from a UK company AFAIK, not chinese. It's only available
under Non-Disclosure-Agreement, they don't just give it out. (I tried
:)
I'm not sure exactly what terms the RTL datasheet are available under,
but in any case it's a copyrighted document.
Cheers,
Sylvain

As the person operating the *.osmocom.org servers and thus legally
responsible for all content on the sites I would like to ask everyone
not to do so. Also, I would like to ask you not to request others
to publish copyrighted material without approval by the owner.
So if anyone has approval from Elonics or Realtek to publicly post those
documents (which I doubt, but it is possible theoretically): Please go
ahead. Otherwise: Don't.
Regards,
Harald

Hello
I at least learned something about the Chips in these new TV Tuner Sticks, the tuner is
perhaps British. Information about these chips, it seems, is kept secret for some
(unimportant) reason I cannot understand. You would think a group or company that
manufactures something for sale would publish how to use it; non-disclosures are merely
ways to protect trade secrets. These chips are in the open and may be reverse engineered
or hacked as is the case in this forum, not publishing their datasheets does not protect
them, it only limits their sale. Perhaps someone who has a non-disclosure with them should
convey that to the Fabricator.
Thank you

Hi Jay,
this is very rapidly slipping off-topic, but FYI:

One of the typical reason is quite simple and (unfortunately)
understandable:
If you openly document how your hardware works, then you are inviting
patent trolls and patent lawsuits. If they can go to court and show
your own documentation as evidence, you will have a hard time arguing
that the documentation was wrong.
If the documentation is not publicly released and under NDA, than any
patent troll getting hold of it (and/or their collaborators) would have
been violating the NDA.
If there is not documentation, then the patent troll would have to
actually do silicon reverse engineering and invest money and time before
they have evidence. And then that evidence gets questioned, and the
process how it was obtained. Possible, but much more effort.
The point is not whether a given device infringes a patent or not. The
point is simply that there are companies out there who simply pick the
easiest targets. And unfortunately those that have open documentation
are easier to attack than those that don't :(
