SDR 1000D Operational Overview

The RECEIVER- is an advanced direct conversion design using direct digital synthesis. It converts RF directly to audio. Separate in-phase and quadrature signals are then fed to a computer sound card for digital signal processing using an innovative in-phase and quadrature (I and Q) image-reject approach. These connectors are provided on the rear panel.

The TRANSMITTER-of the SDR-1000D hardware is designed to take processed audio from the sound card and convert it to RF. The transmit conversion includes boosting the RF to 100Watt on 160 meters through 10 meters.

The true "heart" of the SDR 1000D is NOT inside the black box! Data is the "lifeblood" of this radio; the hardware is just a portal between the analog and digital worlds.

The SDR 1000D software -know as PowerSDR-determines how a received signal will be demodulated. It also creates the transmitted signal according to the mode you wish to operate. Therefore this gives the SDR, the most literal sense of the term; Software Defined Radio !

This SDR system is NOT to be confused with a microprocessor controlled radio that offers updateable firmware. The changes implemented by firmware updates are limited in scope because the inflexible hardware defines and constrains what can be done with the radio. Not so in the SDR-1000D software. In fact the software, is the radio to the greatest extent possible. Very large changes can be made when you modify the software, of an Software defined radio.
