Short Wave
RIZ's new generation of SW broadcasting transmitters is designed with a completely solid state modulator and tube in RF stage only.
These transmitters are superior to any other standard transmitter in the same power range.
Transmitters are capable for standard amplitude AM, digital DRM or SIMULCAST modes of operation.
The transmitters use a multifunctional display menu to monitor all relevant parameters.
These transmitters, as well as all other RIZ transmitters, provide operating and maintenance personnel with maximum safety in compliance with IEC60215 safety standards applicable to radio broadcasting equipment.
MAIN FEATURES:
- High overall efficiency
- Completely solid state modulator
- Microprocessor and DSP technology
- Digital broadcasting compatibility (DRM)
- Remote control for unattended operation
- Simple and cost effective maintenance
- Mobile or stationary versions available
* Standard frequency rate is stated. Other frequency ranges are available on request in accordance with ITU recommendations for that type of equipment band service.
All RIZ SW transmitters are capable of operating in the ambient temperature range 0 – 45 °C (0 – 50 ° C) without influencing or changing the transmitters characteristics.
