Re: Feeding audio signals into phone lines

["BruceR" <razrbruce@xxxxxxxxxxxxxxx>]

I think what you need is a "Telephone patch" which can be a pro model
like this:

or a homebuilt impedance matcher to match the out put of the speen synth
equipment to the 600 ohm phone line.  The Ramsey unit is ony $70 but
needs to be built.

Also, check with local HAM radio operators in your area. They may have
just what you need lying about somewhere.
