I'm wondering if I can work with 10 RF 433 emitting short on/off data to 1 single RF 433 recever.
What made you think that your question has anything to do with the Website and Forum section which is clearly stated to be for "Improvements for the web system, applications to moderator, spam, etc."? I have suggested to the Moderator to move it to the Networking section.
This sort of carelessness makes unnecessary work for the Moderators.
