What sort of range are you able to get sending s/pdif on those? I am really interested in playing around with that a bit. 2.4 is very congested around my home but 5.8 may be a workable wireless solution for sending audio.

I would be curious to see what sort of range a pair of yagi's would give you.

@miklk1973 So would I... It's been on my mind to attempt to construct a pair of yagis (although how accurately I'll manage that for 5.8GHz is yet to be seen). Other thoughts are to construct something out of parabolic cookware, or find a metal tube to make a correctly sized waveguide "cantenna". I'm hoping that with better antennas S/PDIF will work too (it works at shorter distances, I've got down the street before). I have another video showing S/PDIF going over these senders at short range.

@miklk1973 Well it was working about 180m fine. I've since had a look at the SPDIF output on an oscilloscope and it's really bad. The waveform is being seriously deformed as there's just not quite enough bandwidth on the video channel for a clean 44.1kHz SPDIF signal. This would have been adding to the distance problems and it's a wonder that it seems to work at all!

what model senders are being used?

@miklk1973 Philex 27998R. Just whatever was going on eBay cheap at the time! Need to pick this project up again and make better antennas, tomato purée cans are a bit too large for 5.8GHz.
