Transmitter Fidelity+ 10

10 kW Tropical band SW Broadcast Transmitter FIDELITY+ 10

The RIZ FIDELITY+ 10 is the newest RIZ's TROPICAL BAND DIGITAL totally solid state transmitter, having 10 kW carrier output power, capable for AM, SSB, DRM, CW operation modes.

 

A DRM Exciter / Modulator is integrated in the transmitter and there is no need for additional, external DRM equipment at all.

In DRM operation, the FIDELITY+ line of transmitters completely meets the latest DRM standards.

 

To change the mode only a button on touch screen main menu has to be pressed.

 

The new approach in mechanical design and the out-phasing modulation principle make the RIZ FIDELITY+ 10 smaller, more compact and more efficient transmitter.


As all RIZ's transmitters in the FIDELITY+ line, the FIDELITY+ 10 is also capable of operation at any frequency within the tropical band SW (3.2 MHz - 9.9 MHz). Transmitter is factory preset at two operating frequencies with fast switching between them.

 

  • High overall efficiency
  • FM like audio performances
  • AM, SSB, DRM, CW operation
  • DRM Modulator Exciter is integrated in the transmitter
  • Redundancy, extreme reliability
  • User friendly control and monitoring
  • Remote Controllable for unattended operation
  • RF out-phasing modulation principle
  • Fast switching between two operating frequencies (<1 min)
  • Compact design
