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@lists.osmocom.org or post them to http://sdr.osmocom.org/trac/wiki/Hardware
Thanks
Hi,
Is the reason why Docs for the ELONICS E4000 are not published because it is Chinese?
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
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 :(

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
