Excellent RF performance in congested areas
Careful analogue design is the key issue to achieve the best collocation capabilities possible. The 7000 series of radios is designed with no compromises regarding the synthesizers and analogue front end. This together with a linear power amplifier design, strictly controlled by an ultra fast digital signal processor, makes the radio the ultimate choice for professional G/A applications.
Advanced digital signal processing (DSP)
The receiver and transmitter use the most powerful digital signal processors to perform the intermediate frequency (IF) and the audio frequency (AF) filtering. In addition, all the modulation and demodulation tasks are performed in the signal processor. This means improved product control, less tuneable parts and improved reliability.
Remote control over Ethernet / RS232 / RS485
The radio units have alternative ways of being remotely controlled, making them easy to fit into an existing infrastructure already available on the site. The radio units are controlled using SNMP (Simple Network Management Protocol) over UDP, or remote control over TCP, both using the built in 100 Base T ethernet interface. Either by using Jotron's dedicated Radio Access and Control System - RACS III or by a standard SNMP management application. Alternatively, set up and control can be done using the serial RS232 or RS485 ports.
No tuneable parts
There are no tuneable parts inside the radio units. No tuning, or special tools are necessary when changing frequency / modulation or to maintain the radio.
Easy set-up and control
All parameters can be set and adjusted electronically from the front panel or from the remote interface. The front panel contains a graphical display, menu buttons and switches that are used to set up the radio - no external equipment linke a PC or a signal generator are necessary to control the frequency or to adjust any parameter internally in the radio.
AM and FM operation
The radio can be operated in the following modes: AM or FM voice.
Compact design
The receiver unit is a complete stand-alone receiver with built in power supply weighing only 1.7 kg. The transmitter unit weighs only 3.0kg. A complete transceiver consists of 3 units (transmitter, receiver and power supply) and the total weight is only 6.0kg. The modular and compact design makes the radio the perfect choice for distant sites that are hard to reach.
BITE system that detects failures
The BITE system continuously monitors vital points in the radio units. An error is instantly detected and reported in multiple ways. The unique main/standby concept of the Jotron 7000 series can automatically switch the operation to a standby set upon an error, providing seamless communication for the user.
Keying options
Keying options available in the transmitter includes positive and negative voltages (up to 50V), keying to ground and phantom keying on the audio line. In addition the keying option includes in-band tone signalling both ways: PTT and squelch with configurable tones for easy integration with any VCCS system.
Continuous duty cycle
The transmitter is designed for continuous duty cycle. This makes the radio the perfect choice for VOLMET and ATIS applications requiring continuous transmission. The unique cooling concept used on the transmitter, keeps the temperature low, and the operational lifetime of the equipment high.
Offset operation
Setting the offset carrier is just as easy as setting the frequency of the transmitter. Offsets at ±2.5, ±5.0, ±7.5 kHz are available.
