TW7000 SERIES HF TRANSCEIVER section 4

PC-style keyboard can be used for message composition. All messages, whether transmit or receive, are

displayed on the radio’s custom LCD display and stored in memory.

7000ALE

FED-STD-1045A ALE module that provides a fully interoperable system for ALE operations, including high-

speed scanning, sounding, link quality analysis, and send/receive AMD (“orderwire”) message capability. It

provides selective calling as well as “best available frequency” selection and includes the real time clock option.

All channel and ALE parameters can be programmed into the radios either from the front panel or using one of

Datron’s custom software programs (DatronLINK-2, DatronLINK or RC2). The radio keypad or external PC-

style keyboard can be used for message composition. All messages, whether transmit or receive, are displayed on

the radio’s custom LCD display and stored in memory.

7000CW

500 Hz narrowband filter for CW operation. It is installed on the 5 MHz IF subassembly in place of 7000WB1

data filter (when ordered).

7000CW1

500 Hz narrowband filter for CW operation and 3000 Hz (300-3300 kHz) wideband filter for data operation.

With this option, the wideband filter is used for voice operation.

7000ENCR *THIS ITEM IS USML

High-level digital encryption module for voice transmissions. It contains a three-tiered key system (system,

network and local keys) with provision for up to 200 local encryption keys. All three levels of keys can be

programmed into a smart module (701450) with the 7000CMS crypto management system. The network and

local keys can be programmed with the DSP9000 ciphering system. The keys are loaded into the radio from the

smart module. The 7000ENCR is compatible with the DSP9000-HS encrypting handset. Order cable C992029

for use with the DSP9000. For more information on key management systems, contact your Datron Sales

Representative.

7000HS

High-stability reference frequency option. Provides a reference frequency stability of 0.1 parts per million.

It replaces the standard reference crystal oscillator with a precision OCXO (Oven-Controlled Crystal Oscillator).

(Note: the standard frequency stability of the 7000 transceivers is 0.5 ppm)

7000NB

This is an impulse-type noise blanker that is designed to allow operation of the 7000-series transceivers in a high-

noise environment, as in the presence of vehicle ignition noise. The noise blanker can be externally controlled

from the front panel.

7000RCDR

Combines receive and transmit audio and routes them to the Accessory #2 connector on the radio’s rear panel. Typically

used with a continuous recording device to monitor RX and TX communications.

*USML REQUIRES WRITTEN AUTHORIZATION FROM THE U.S. DEPARTMENT OF STATE PRIOR TO EXPORT OR RE-EXPORT.
