SDR 1000D Rear View (Hardware)

Starting at the upper left corner of the rear panel you will find the DC input terminals. 13.8VDC - #12 AWG or greater power cord should be used for 100W operation. The far left connector is a BNC type used for 100W Power Amplifier Antenna Connector. (This antenna connector is used for all bands if the 100W amplifier is installed). The connector located toward the top center of the rear panel is an Auxiliary Input Connector for an optional External Reference Oscillator.

The far right hand BNC type connector is to used if the 100W amplifier is not installed. (When installed, this connector is in parallel with the amplifier input circuit.) On the right hand upper corner there are two connectors used for Two Meter transverter, transmit and receive.

The connector under the BNC connector is used for Earth (RF) ground. The lower right hand side of the rear panel houses the external control connector, D type, as well as the Parallel Port Connector, which connects to the PC parallel port. The option SDR-USB USB-to-Parallel Adapter connects to this port.

The smaller connectors across the center right side of the panel are CW/paddle connector, line output (speaker output) on sound card, high impedance output for amplified speaker or headset, line to sound card, and microphone input on sound card.
