Does anyone know of a source that either sells plans for or kit to build
a dsp for amatuer radio?. Specifically , I would like to use it in
conjunction with a shortwave receiver. If so, would you please post the
information. TIA.

You should also look at Lyle Johnson's (KK7P) web page:
http://www.fidalgo.net/~wa7gxd/

Lyle uses the Analog ADSP-2185N DSP chip on a small PC board.
This has successfully been used as an audio DSP with the Elecraft K2 and
the Software Defined Radio DSP-10 by Bob Larkin, W7PUA.

Lyle has an interface board and a number of programs appear in the ARRL book
" Experimental Methods in RF Design", Chapters 10 and 11.
He had updates on the use of the KDSP10 and DSPx in conjunction with this
book.

Good luck !
