The TW7000 Series is an advanced transceiver system which provides the total system solution for all your HF requirements.
The system is reliable, easy to use and provides long distance voice and data transmission capability over the 1.6-30 MHz high frequency (HF) range. The knowledge and experience gained from 20 years in the HF radio business was used to develop this completely new product family which utilizes the very latest in electronic and packaging technologies.
Using multiple microprocessors and new technologies such as Digital Signal Processing (DSP) and Direct Digital Synthesis (DDS), the TW7000 provides built-in features such as Automatic Link Establishment, Voice Enhancement, and Encryption. These powerful technologies and features have been carefully balanced with the need for ease of operation, high reliability, simple maintenance, and affordability.

Multimode Capabilities
All standard modes, including USB, LSB, CW, PCS and AME, are available. A wide band data option is provided for high-speed data capability. The optional DSP module allows a number of customized functions including voice enhancement.
Reliable Multi-Level Power Amplifier
Output power is conservatively rated at 125-W PEP, 100-watts average, in continuous keydown operation. Three front-panel-programmable levels are available which default to 5, 20, and 125 watts. Complete VSWR protection is provided.
Advanced Receiver Design
Designed to cope with today’s crowded, noisy HF spectrum, the TW7000’s receiver performance is on a par with most dedicated surveillance receivers.

Microprocessor Control

Two high-performance processors are used to control the operation of the TW7000. In addition to the main radio controller, a second processor is used in the front-panel assembly so that the latter can be removed and used as a remote-control head for the transceiver.
Direct Digital Synthesizer
An advanced, fast-switching DDS circuit is the heart of the TW7000 synthesizer. It provides a low-noise and spurious output, and permits fast scanning and high resolution. Although 10-Hz channel spacing is standard, the synthesizer is capable of operating in 1-Hz steps for special applications.
Alphanumeric Keypad
The standard front-panel keypad has full alphanumeric capability.
Alphanumeric Display
The TW7000 has a high-resolution, backlit, custom LCD display which indicates channel number, frequency, time, clarifier offset, mode, and relative signal strength/output power, as well as the status of the installed options. Two alphanumeric lines display the BITE status, sub-menu data, and can also be used to compose or receive ALE orderwire or data messages. A 24-hour clock/timer is optional.
Modular Construction
The utilization of a “no-harness, full plug-in” packaging concept permits easy field-level repair and upgrades, as well as quick installation of any option card.
BITE Capability
Automatic BITE capability, with fault isolation to the module level, is standard in the TW7000. BITE status messages, which cover a variety of possible failure modes, are presented on the display. This allows even unskilled operators to troubleshoot the radio at the field level.
Failsafe Input-Power Protection
The TW7000 is fully protected against reverse polarity, over/under voltage, power surges and spikes.

Remote-Control Capability
A variety of remote-control capabilities are offered. An extended front panel control can be used as a: controller for short-distance operation. Full- function remote control is available using either the ISDN protocol (medium distances) or FSK tones (unlimited distances) over any voice-grade 2- or 4-wire line. The TW7000 is also capable of full computer control utilizing a variety of interface standards.
Dual ALE Capability Options
In addition to the widely used and cost-effective TRANSCALL system, the TW7000 also offers a full FED-STD-1045 compatible system which provides advanced features such as high-speed scanning, sounding, link-quality analysis, and send/receive orderwire message capability. Both of these ALE options provide selective calling as well as “best-available-channel” selection.

DSP Voice Enhancement
The optional plug-in Digital Signal Processor (DSP) Voice Enhancement option makes it possible to tailor the TW7000’s features and performance characteristics to a wide variety of specialized applications.
High-Speed Data Option
The optional high-speed data option permits reliable transmission of high- speed data, Group III FAX or video images, even under uncertain HF propagation conditions. This option has been designed to the U.S. MIL-STD-188-11 OA serial-tone protocol and provides up to 4800 bps data-transfer rates (or 2400 bps with full-error correction). When used in conjunction with the ALE option and the TW9200 “DATACOM” Message Terminal, this integrated system provides a cost effective, fast and reliable solution to long-distance data communications requirements.
Encryption Option
These options provide either high-level digital encryption of both voice and low speed data communications or medium level voice scrambling.
