RE: TI-H: building remote link



I'm really shooting off the hip here, but this is a very realistic 
project. There are Tx and Rx available for about $40 each. All that would be
needed is a interface to convert TI data to modem then vice versa.

I am not interested in this but if someone is, I can supply the manufacture 
to the pre-built Rx and TX.

If that's Michael Jan's Radio Transfer Link (which I'm sure it is), forget 
about it. It's a hoax and nobody has ever got it to work. I wonder why
people still spread it around...

Usually, you just connect all "ground" symbols together, maybe attach them
to the metal case of the device. Also, usually - pins of batteries and
other power sources are connected to the ground, but not always. Interfaces
usually have a ground too, and their ground pins are often (but not always)
connected to the ground potential of the device.
