Software Defined vs. Controlled

• Controlled
• PC Control of Fixed Radio Capabilities
• Defined
• 100 of Modulation, Demodulation and Control
  Capabilities Software Defined, Thus Upgradeable

3
Philosophy Maximize Software.Minimize Hardware

• Continuous Enhancement Just Gets Better!
• Performance Not Possible in Analog
• Less Analog gt More Linear
• Rig for Each Mode/Style of Operation
• Open Source GPL Many Contributors
