Can anyone help with info/links dealing with transmitting wirelessly, throughout a home, stereo audio 20-20khz, and also a small 9600 baud data channel?

Richard.

Go to your favourite search engine and type in Videosender. The X10 product
will probably pop up but there are a variety of manufacturers offering
similar products operating on 2.4GHz

Has two audio channels and you can use the video channel to send data at
considerably more than 9600 bits/sec. The X10 product also has a back
channel on 433MHz to relay your infrared remote control.

Regards
Chris

The X10 folks have been advertising a wireless audio link system at a pretty
reasonable price. check out their web site at http://www.x10.com
They also so wireless video which may be hackable for a data link.

For audio, there are commercial devices readily available from
Circuit City/etc - run at 900/2400 mhz, selling for under $100.

More specifically the data channel is both RX and TX, and the audio is just TX on one end and RX on the other.

R.

One way may be to send the audio as 600 ohm balanced lines down 2 pairs of
a CAT5
cable. The Analog Devices SSM2142 (driver) and SSM2141 (receiver) chips
work well.
For the data you could use 2x MAX485's et each end. (1ea for Tx & Rx) This
would use
the other 2 pairs in the CAT5 cable. Not sure if you'd have any crosstalk
between the
data and audio lines. Using MAX483's (slew limited) may help there. I guess
it all depends
on what the intended application is and how much fiddling around you want
to do.
