DSP
 

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.

SGC www.sgcworld.com has such a critter. It's a tad on the pricey side,
though. Seems like they had them for sale at Dayton last year, but the web
site says coming soon.

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 !

You may want to have a look at
http://www.nitehawk.com/sm5bsz/linuxdsp/linrad.htm

This is the Linrad home page
Take the output of your Rx and feed it to the computer sound card.
You will have to do a bit of work getting up to speed on Linux if you
are not already familiar. However, the newer Linux distributions are
becoming better than Windows in terms of usability, in my opinion. The
program itself also takes some work to set up. However, you can use a
relatively low power computer eg 400 MHz PII, which are available
cheaply now as your DSP platform.
This is a very sophisticated package which is designed originally for
144 MHz EME.
If you really want to get into it, you could build the hardware as well
