Software Defined Radios anyone?
 

I like to build a simple SDR. Anyone used a simple DSP chip to do this?
Maybe the PICDsp?

"Simple," "SDR," and "DSP" do not belong together in the same
sentence. Anything you do with that kind of hardware is going to be
inherently complex. Be prepared to write a lot of code.

Good luck.

The SoftRock uses the PC to do the DSP:

Almost by definition the hardware is simple. And experimentation in
software is a lot easier and less painful than hardware experimentation.
But you are correct that there will probably be quite a bit of code,
although not all of it needs to be written from scratch.

If you graze the Microchip dsPIC forum, a British ham talked about such a
project a few months ago, sorry I can't recall his name. I think he may
have posted some stuff on the PIClist, too. He did use some sort of codec,
along with the dsPIC. I picked up the codec and dsPIC with the intent to go
down that path, but those round tuit thingies are hard to come by around
here.

Ah... This is what I get for not grazing said forum.

Round tuits are hard to find here as well. Thanks for a more
expansive reply, though. I may go have a look myself.

Keep the peace(es).

....join the picastar group. it's the most amazing group of hams i had
the honour to attend!
you'll find averything you'll need on SDR's!

the Britton in question is Peter Rhodes G3JXP, the high priest of the SDR. they also have the code for the DSP and its amazing. You can take it as is and it works!

....should be "G3XJP".
