Slide 1

Elite Software Defined Radio – An Open Source Design – Lyle Johnson, KK7P Microhams Digital Conference, 2007

Slide 2

SDR: What Is It? Programming Defined Radio (SDR) means a radio whose essential capacities are characterized by programming. Not simply PC control (CAT) Based on Digital Signal Processing (DSP) SDR programming can for the most part be changed or overhauled by the administrator. Ten Tec items since Pegasus (e.g., Jupiter, Argonaut V, Orion) Most different brands don't permit this To fulfill our sanction for Self Education and Advancing the Radio Art, SDR programming is ideally Open Source dTTsp from N4Hy and AB2KT essential case Core of PowerSDR Basis of most work done in HPSDR extend LinRAD, GNURadio, Pic-A-Star, DSP-10, EMRFD 18 MHz Project, and so on. Other SDR programming is uninhibitedly accessible yet not open source Rocky, KGKSDR, Winrad Spectravue is shut however has open-source interfaces to permit 3 rd party module and development

Slide 3

SDR: Examples W7PUA's DSP-10 is a wonderful case of SDR Based on inserted DSP Open Source See QST 9/99 – 11/99 or EMRFD http://www.proaxis.com/~boblark/dsp10.htm Flex Radio's SDR-1000 is first business Amateur SDR Flex makes exclusive equipment K5SDR Introduced QSD/QSE QEX July 2002 1 st of 4 Part Article Community composes application code Originally by Flex now just composes GUI and Drivers $1500 http://www.flex-radio.com/

Slide 4

SDR: More Examples Tony Park's Softrock Series QSD for Rx, QSE for Tx $20 for Rx (1 or 2 band) $40 for Tx/Rx (1W, 1 or 2 band) http://groups.yahoo.com/aggregate/softrock40/Hendricks QRP Kits Firefly Xcvr QSD Rx Tx not SDR $65 (1 band, CW) http://www.qrpkits.com/firefly.html

Slide 5

SDR: More Examples RFSpace SDR-14 Spectrum Analyzer 14-bit ADC @ 65 MHz $1099 SDR-IQ Similar, $450 Both Products utilize single USB Interface http://www.rfspace.com/products.html

Slide 6

SDR: Pic A Star HF Transceiver Design by G3XJP Based on 16-bit Embedded DSP Original DSP code got from DSP10 Published in RadCom 2002-2004 Chapter in Latest RSGB Handbook http://uk.groups.yahoo.com/bunch/picastar

SDR: DSP Code inside Pic A Star

Slide 8

SDR: Grassroots Action! Hams are customarily experimenters. A gathering was shaped suddenly in late 2005 to play around with FPGAs with regards to SDR. FPGA – Lots of parts in one chip In a matter of months, HPSDR was shaped High Priced SDR?

Slide 9

HPSDR: What's It All About? The High Performance Software Defined Radio (HPSDR) is an All-Volunteer Project to Create Hardware and Software Modules for Experimentation and Advancing the Radio Art. The plans are Open Source. Programming Hardware Programmable Logic (FPGA, CPLD) Translation: A Bunch of Geeks Having a Good Time.

Slide 10

HPSDR: What Is It, Really? Standalone SDR No PC Required Control of SDR-1000 Superior Quality Sound Card Delta 44, Presonus (Exit Stage Left) Spectrum Analyzer (cf. SDR-14) USB Interface Multiple Plug-In Modules

Slide 11

HPSDR: What Is It, Really? Standalone SDR No PC Required Control of SDR-1000 Superior Quality Sound Card Delta 44, Presonus (Exit Stage Left) Spectrum Analyzer (cf. SDR-14) USB Interface Multiple Plug-In Modules Or, similar to the Accountant said when asked what 2+2 equivalents, "What might you like it to be?"

Slide 12

HPSDR: What's It Do? At first, a High-Performance Sound Card for QSD and QSE Radios. SDR-1000 SoftRock Series FireFly Homebrew It Will Soon Add Features Like the SDR-14 Digitize the Entire HF Band in Real Time Spectrum Analyzer Incredibly Flexible Receiver

Slide 13

Open Source Hardware? Numerous Hams are Familiar with the Gnu Public License for Software The source code is uninhibitedly accessible to any individual who asks Any progressions you make must be made unreservedly accessible to any individual who asks – you can't modify it and make it "exclusive" We are Providing the Hardware and Logic Designs Under Similar Provisions The outlines are uninhibitedly accessible to any individual who asks Any progressions you make must be unreservedly accessible to any individual who asks – you can't change it and make it "restrictive"

Slide 14

Open Source Hardware – Part Deaux? TAPR Open Hardware License (OHL) and Noncommercial Hardware License (NHL) The plan materials are unreservedly accessible to any individual who asks Any progressions you make must be made uninhibitedly accessible to any individual who asks – you can't adjust it and make it "restrictive" Public Comment Period until March 7, 2007. The outlines are unreservedly accessible to any individual who asks http://www.tapr.org/ohl.html?PHPSESSID=a44a3e7b07c1ba861f7232d46beb96a7
