User Manual DSP-10 - v3.94  Mike is working 3.96

Mike, KD7TS has made available online the pages and pages of documentation for the DSP-10.  The Manual ver 3.94 is on his web site and is very easy to use.   It has a Table of Contents , that is indexed  to take you right the the area you are interested in reading about.  Very Slick!

Mike's manual web site has moved to http://home.comcast.net/~kd7ts/v380/Preface.html so update your bookmarks.  This site is very useful to have available.  You can also download a download zip file of the whole thing and unzip it into the directory you wish on your computer and you will have the DSP-10 Manual available for immediate use. I downloaded this and made shortcut to the MAN4.HTM file and placed it on my desktop for easy access. Sure works Great and you don't have to be on the internet to use it.

Check it out: It is worth having on your computer for a quick reference.

Thanks Mike!


DSP-10  Initial Setup Testing  

This takes the QST initial Test article and shows the modifications and test procedures in RED used by KO7N and W7CQ  as to what we did to get the TAPR kit  DSP-10 operating.   Hope it helps.

 DSP-10  -  Software Defined Radio

The DSP-10 is a two-meter ham-radio transceiver design by Bob Larkin, W7PUA, using a DSP processor for the IF and audio. Details of the DSP-10 were published in QST magazine for September, October and November of 1999.The DSP-10 can be used for very weak signals communications and has special features for use with microwave transverters.

Full Documentation for the DSP-10 is found on the W7PUA web page

W7PUA Wins ARRL 2000 Technical Innovation Award

from QST September 2001 pp. 67-68

Bob Larkin, W7PUA, helped introduce software defined radios, or SDRs, into the Amateur Radio lexicon, with the design and publication in QST of the DSP-10 SDR.  Pioneering hams have built these units and have used them to do unimagined things, like making two-way QRP moonbounce contacts. The DSP-10 has provided a means for the amateur community to learn about SDRs.

Modern digital signal processing (DSP) technology has made extensive inroads into the domain of hard-wired components. With SDR, software generates radio signals, not a phase-locked loop oscillator, and DSP can generate a signal directly over a surprisingly large frequency range. Software also serves for filtering, automatic gain control and, more importantly, the direct modulation and demodulation of the signals used to communicate.

In the commercial world, SDR can be used over a range of tens of megahertz, with operating modes from "legacy" FM to modern spread spectrum. If a new model is needed, the SDR can be hooked up to a computer and the new program installed--an instant upgrade!  Ham manufacturers are jumping on this bandwagon, too.

Congratulations from W7CQ
