Hi Richard..

?

I thought of this but sunlight seems to play a problem. I have a pair which I use for the TV’s around the house but if direct sunlight they seem to not work..

?

I like the idea of using the POWER plugs. I have seen an intercom system which works this way and pretty well and simple..If I could modulate the signal and demodulate on the other end that would surely work. Like two modems..

Phil you mention TCP/IP and being expensive. What is expensive?? More than buying the RX and TX modules mentioned by Stehan??
