Overview

TitanSDR is a Software Defined Radio receiver, allowing up to 40 NB (Narrowband) channels. It is operated by a commercial PC (Personal Computer), through USB 2.0 interfacing.

Acquisition bandwidth can be split into up to 4 WB (Wideband) channels. WB and NB channels are provided with spectrum and waterfall plots and can be recorded on PC Hard Disk (recording can also be scheduled). WB recordings can be replayed.

Interface to software decoders is through VAC (Virtual Audio Cable) or LAN Ethernet (customizable on request).

Advantages

Until recently multiple monitoring of radio channelsrequired a distinct receiver for each channel and a multicoupler (to split the antenna signal among receivers), resulting in costly systems with significant dimensions, weight and power consumption.

Instead by just connecting TitanSDR to an HF aerial, dozens of radio channels can be listened to (by PC sound cards), recorded (as .wav files) or streamed to software decoders (for decoding of digital formats) in parallel. TitanSDR is ideal to equip monitoring centers and for monitoring missions in which logistics is a critical element, thanking to its compactness.

Software Features

In Receiver mode (as opposite of Player mode), software input is from the receiver via USB 2.0.
Front-End controls allow to set the receiver input (HF or IF), the attenuation to HF input and the preselection filter (if required). After allocating a WB channel (possible bandwidth ranges from 312.5 KHz to 2.1875 MHz), it can be tuned by mouse dragging of the corresponding shaded area over the Panoramic Scope (see next page, upper screenshot). NB channels are allocated on the Wideband Scope (down left side window) and are represented by shaded areas of the same color of their WB channel. By clicking on a NB channel shaded area, its spectrum appears on the Narrowband Scope (down right side window) where mode can be set, as well as channel bandwidth (by editing or mouse dragging its cutoff filter frequencies). All spectrum scopes allow averaging, zooming and choosing among several data windowing alternatives. Custom palettes can be set for NB and WB waterfall plots. Figure below illustrates how outputs of TitanSDR software may be possibly employed.






Overview

In particular NB channels demodulated output can be listened to (by PC loudspeakers), recorded on local HD (wav files) and sent to external third
party software decoders, by VAC or LAN.
Furthermore its spectrum can be displayed (instead of RF spectrum), as well as its waterfall plot. WB channels can be recorded and resulting archive files (proprietary format) can be playedback in Player mode. Recording of each NB and WB channel can even be scheduled through the Task Editor window (screenshot below).



All allocated NB channels are listed in the NB Channels List (see next page, lower screenshot), reporting their status and allowing to recall their controls by simply clicking on their rows.
