Some receivers with an architecture similar to BBRF103 appeared in the web during this look down time.
I tried to contact the authors not for copyright issues, being BBRF103 completely open source but to exchange some experiences. A contacted person wrote me that the project is new and fully original, but I think I reached the re-seller and not the designer.
So I signal my interest in talking with the real authors of the devices.
I list the devices with links to images that are in these weeks at the following links. 

If someone has a review or any other info please send it to me.

Thanks, everyone,  ik1xpv AT gmail DOT com
