CAT-1000 Repeater Controller

Voice Synthesizer

A vocabulary list of 475 words carefully selected for amateur repeater operation is available to construct any of 40 different voice messages. Each message can be 31 words in length. Configure your repeater ID and announcements to suit your needs. Chimes, sound effects and salutations in a female voices are also included. The voice synthesizer fully interacts with you during control and programming operations.

Digital Voice Clock

The voice will announce the time upon request, at the completion of an auto-patch, during repeater IDs, or on the hour through the grandfather clock feature.

DTMF KeyPad Test

A DTMF keypad test will read back the numbers decoded in a synthesized voice. This includes the words "STAR" and "POUND."

Courtesy Tone

Memory space is provided for the storage of ten custom courtesy tones. Each tone can consist of up to three different tone frequencies of various lengths and separations.

LITZ Emergency Alert

LITZ is a new system promoted by the ARRL to provide a means for a repeater user to request emergency assistance without being familiar with the operation of the repeater. If a repeater user transmits a DTMF [0] for three seconds, the CAT-1000 will alert the control operators.


A full feature auto-patch with storage for 300 speed dial numbers highlights the CAT-1000 Repeater Controller. Each speed dial location accepts numbers of up to 11 digits and includes space for the users call letters. The same is also true for the 10 Emergency speed dial locations. The repeater reads back the regular calling number prior to dialing. This feature can be suppressed by a mic key-click. A 20-position table stores telephone numbers or whole prefixes to be locked-out. Area code discrimination permits access to certain area codes. Last number re-dial, hook flash, and time extender commands round out the features. In addition to the Reverse auto-patch, full telephone control and programming provides extra security.

Monitor By Telephone

This feature permits the control operator to call the repeater by telephone and monitor repeater activity. While in this mode, the transmitter can be turned on and off. This is useful when investigating inter-modulation problems.


An advanced 60-position scheduler fully automates the operation of the repeater. Pre-schedule your repeater's operation to one-minute accuracy. Program the hours, minutes, day of week, or day of month and month of year. The CAT-1000 will do the rest.

Repeater Control

Twenty-five prefix numbers control repeater operation. Each prefix is programmable from one to seven digits depending on the security you require.

Repeater Control Channels

The CAT-1000 has 64 remote control channels. Divided into groups of eight, according to their function, they can be manually controlled through the repeater, link or telephone.


The CAT-1000 will switch to a CW ID when a user talks over the voice ID. You program the speed and tone frequency. If the repeater is at rest, ID #1 will be sent. If the repeater is in use, ID #2 will be sent.

Repeater Timers

A total of 19 timers control repeater operation. Each timer is user programmable to afford maximum flexibility to suit your requirements.

User Function Switches

Eight switches control equipment at your repeater site. Controlled manually by DTMF commands, or by the scheduler, they can be made to turn OFF, ON or Momentarily change state, any time you choose.

DTMF Regenerator

The CAT-1000 memory is capable of storing up to 40 DTMF commands that can be sent manually or automatically by programming the scheduler.

DTMF Command Generator

Store forty DTMF commands in the CAT-1000 memory. These commands can be sent manually or automatically by programming the scheduler.

Hardware Inputs

Eight hardware inputs activated by a positive voltage from other equipment at the repeater site, causes the CAT-1000 to execute any repeater command.

Repeater CTCSS Override

When the repeater is in the CTCSS mode, a user without a CTCSS encoder can activate the repeater by entering a special DTMF access command. The controller will respond to a carrier input. After a short period of inactivity, the controller will revert to the CTCSS mode.


By entering a macro number, the CAT-1000 will execute up to ten commands in a string. Store up to 40 macros in memory. One Macro can be used to call a second Macro. Customize the control functions to suit your needs.

300 Baud Modem

Program the CAT-1000 with your computer through the on-board modem. Use any popular communication program. Down load the CAT-1000 memory and store it on disk. You will never have to manually reprogram again.

Active Memory Save

Configure the CAT-1000 to suit your special requirements. Save the current settings of the control channels, prefix codes, timers and the first twelve voice messages. Space is provided for eight memory saves. These memory saves can be later recalled with a DTMF command.

HF Remote Base Interface

The CAT-1000 offers a serial port for HF transceiver control. The CAT-1000 will generate ascii commands to control the TS-440 and FT-767GX transceivers. The CAT-1000 will announce the status of the various transceiver functions. The CAT-1000 receives and sends information in both RS-232 and TTL format.

DTMF Paging

Enter a DTMF page on the telephone line and the CAT-1000 will rebroadcast the DTMF page to alert a repeater user with a DTMF squelch equipped radio.

Link Transceiver Control

Control a link transceiver. Turn the link ON, OFF or enable just the receiver. After a pre-selected period of inactivity the link will automatically disconnect.

ED-1000 Windows Editor

Use the optional ED-1000W program to edit the eight memory files. The editor includes a print driver and will work with any computer using a 3.1, 95, 98 or NT operating system. Once the files have been changed and saved to disk, they can be uploaded using X-MODEM protocol.

WS-1000 Weather Station Firmware

Provide timely weather announcements on your repeater system. Connect a Peet Brothers Ultimeter U-100, U-800 or U-2000 Weather Station or a Davis Weather Wizard III to the serial port of Your CAT-1000 and install the WS-1000 firmware up-grade. Integrate temperature, wind speed, direction, high and low temperature and rainfall rate into any of the CAT-1000 voice messages. Program special weather report messages or make the weather part of your identifications, grandfather clock or tail messages.

Audio Delay

The DL-1000 will eliminate the squelch noise crash and the chirp when DTMF muting is enabled. Connectors are provided for both the repeater and link inputs. With a sampling rate of 62KHz, the DL-1000 delivers high quality audio. A dipswitch selects delays of 500, 250, 125 or 62 milliseconds.

Digital Voice Recorder

Add the DVR-1000 Digital voice recorder to the CAT-1000 controller. With a total record time of two minutes and sixteen tracks, the DVR is fully integrated into the CAT-1000 control and command structure. Features include on-board battery backup and the ability to play, record and erase the tracks through the radio or telephone line. The sampling rate is selectable between 32KHz or 50KHz. A special signal report feature permits a repeater user to make a seven second recording for immediate play back to evaluate the signal quality.

Doug Hall RBI-1 Interface

The RBI-1 receives serial data information from the CAT-1000 and converts it to the format required to control the Kenwood transceiver. All connections to the Kenwood transceivers are made through the microphone jack. In addition to band, frequency, offset, memory selection and transmitter power, CTCSS tones can be selected remotely. The RBI-1 supports the following Kenwood Transceivers: TM-221, TM-231, TM-241, TM-321, TM-331, TM-421, TM-431, TM-441, TM-521, TM-531, TM-541, TM-621, TM-631, TM-701, TM-721, and TM-731.
