EscrowUnlt © squaretrade warranty v2.0 This is a new Vertex 4207 501 Channel 45 Watt UHF (70CM) repeater with a new top of the line CAT-700B controller, designed for operation in high RF environments. With a tighter receiver, higher intermode rejection and adjacent channel selectivity this repeater is exactly what you've been asking for. Crisp, clear audio, you will love the way this repeater performs. Professionaly assembled and programmed to you specifications, frequency (4 channels), CTCSS encode, decode or both, power level and more. Frequency stability is better than 2.5ppm. Adjacent channel selectivity is 78/70db, intermodulation is 80/75db, spurious image rejection is 80db. This repeater specs tighter than any repeater we’ve offered to date. If you need a repeater that works well in a high RF environment this is the one for you. Fully assembled and ready to go on the air. Just add a 13.8 VDC 20amp power supply (AC/DC converter), antennas or duplexer and your ready to talk. We assemble this repeater using two Vertex VX-4207 UHF mobiles, a full featured CAT-700B controller and custom made interface with EMI shielding. A cooling fan is mounted under the transmitter to keep it cool during heavy use. The fan is controlled by a thermal switch rated at 85F.

Each message can be 23 words in length. Configure your repeater ID and announcements to suit your particular needs. The voice will announce the time upon request, during the repeater ID, or on the hour through the grandfather clock feature. The RBI-1 receives serial data information from the CAT-700B and converts it to the format required to control the Kenwood transceivers. 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 CAT-700B offers a CI-V Interface to control the IC-706 transceiver. Upon receipt of a DTMF command, the CAT-700B will generate the required ASCII commands to control the transceiver and use its voice synthesizer to announce the status of the various transceiver functions. A DTMF key-pad test will read back the numbers decoded in a synthesized voice. This includes the words "STAR" and "POUND". Memory space is provided for the storage of eight custom courtesy tones. Each tone can consist of up to three different tone frequencies of various lengths and separations. An advanced 40 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-700B will do the rest. The CAT-700B will switch to a CW ID when a user talks over the voice ID. You program the speed and tone frequency. Adding a remote base transceiver to your repeater system has been greatly simplified by the addition of a noise squelch COR generator to the CAT-700B controller. This circuit will produce the necessary COR logic level from the transceiver’s discriminator audio output. It is no longer necessary to open the transceiver and search through the squelch circuity looking or a changing DC voltage to represent receiver activity. The CAT-700B offers full control of the link port. You can turn the link transceiver on and off, or just enable the receiver. If you choose, after a preselected period of inactivity the link will automatically disconnect. Two DTMF decoders insure that even when the repeater is in use, the CAT-700B will accept commands to enable and disable the link from the link side. By entering a macro number, the CAT-700B will execute up to ten commands in a string. Store up to 40 macros in memory. Customize the control functions to suit your needs. Configure the CAT-700B for day time, night time, emergency net and severe weather operation. Save the control channels, prefix codes, timers and the first twelve voice messages. Space is provided for six memory saves. These memory saves can be recalled by the schedular or manually with a DTMF command. Four hardware inputs activated by a voltage from other equipment at the repeater site, causes the CAT-700B to execute any repeater command. External repeater control or information about the repeater site will be instantly available. Four 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. Store forty DTMF commands in the CAT-700B memory. These commands can be sent manually or automatically by programming the scheduler. The CAT-700B will mimic your DTMF input. In sophisticated repeater systems, it is often necessary to pass DTMF commands to distant repeaters within the linking system. The CAT-700B will swallow your tones and then regenerate the tones free of noise and distortion. This will insure reliable control of your linking network. 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 voice synthesizer will say: "OK UP" and controller will respond to a carrier input. After a short period of inactivity, the controller will revert to the CTCSS mode. An extensive set of programming commands permits you to customize your repeater’s operation. Protection is provided by a user programmable [7] digit un-lock number. Once un-locked, use the programming commands to set the clock, program the CW ID and voice messages, load link frequencies and change prefix codes and timer settings. The CAT-700B includes a 4800 baud RS-232 port. When connected to a computer the entire contents of memory can be up-loaded or down loaded to be displayed and changed with the optional Windows Editor. Thirteen prefix numbers control repeater operation. Each prefix is programmable from one to seven digits depending on the security you require. A total of sixteen timers control repeater operation. Each timer is user programmable to afford maximum flexibility to suit your requirements. Short timers can be set to a maximum of 10 seconds in 0.1 second steps, while long timers have 1.0 second resolution up to 30 minutes. **************************************************************** The item above is guaranteed to be as described.
