IR range/wide area extender

That's interesting yes, thanks.
I guess I would need to purchase the journal for getting the full article.
Maybe I should do that.

Although, I have a stereo 4 channel level control that works with a small radio connection between the three stations.
I designed that with a PIC controller and small RF modules, maybe 15 years ago!
Maybe I should modify that. It is set up so that it repeatedly sends commands to the receiving end until it gets back an acknowledge that it is received.
That's how I overcame at the time the issue of missed messages.
