- Sophisticated graphic user interface (GUI) for easy maintenance and troubleshooting.
- Dual channel (490 kHz and 518 kHz) operation.
- Synthesized exciter uses advanced DDS technology to produce highly stable RF drive at the desired operating frequency.
- Extensive automatic fault monitoring, with 256 event log, for faster troubleshooting.
- Extensive remote control/monitoring and diagnostics for fewer site visits
- Remote control and monitoring of the ATU to limit worker exposure to strong RF fields, in keeping with Safety Code 6 / IEEE C95.1-1999.
- Designed with intent to comply with CE requirements.
- High overall efficiency (70% or better) results in low power consumption and reduced operating costs.
- 170 - 270 Vac Switch Mode Power Supplies.

The KTX-2012-1000 transmitter works in the MF/HF frequency range from 1.6 to 30MHz and can deliver up to 1 kilowatt PEP of RF signal into a 50Ω load. The KTX-2012-1000 transmitter uses up-to-date technologies:
- The RF signal is generated by a digital synthesizer with DSP and DDS,
- Use of last generation of MOS-FET solid-state power amplifiers,
The KTX-2012-1000 has native IP capabilities with the following features:
- Control through a high level WEB server (both for settings and monitoring),
-
High level Monitoring through SNMP (MIB supplied) as an option,
-
Data intput for Voice, DSC and NAVTEX; it is fully compliant with the ED137-B standard (VoIP with SIP),
The KTX-2012-1000 is specially designed to be installed into the maritime coast station fulfilling the GMDSS requirements. It includes one 19" - 32U cabinet (without option), the power supply, the synthesizer, the amplifier and the harmonic filter for an easy installation on site. The main power supply is single phase from 100/240VAC - 50/60Hz.
The KTX-2012-1000 transmitter can be used for Voice, DSC, NAVTEX ( 4 209.5kHz) or other purpose (USB, LSB etc.).
As an option, the KTX-2012-1000 transmitter can control the external KTU-2052-1000 Antenna Tuning Unit (ATU), if the transmitting antenna is not a wide band one.
Other available options are:
- LCD Display for Local Control
- Integrated Matching Box
- Redundancy Switch 2:1
- Tx antenna Matrix
- Tx Antenna Matrix ('M' inputs -> 'N' outputs)
- Local Voice Operator Console with Integrated MF/HF Voice Receiver (KRX-2072)
MF/HF ATU
KTU-2052-1000: 1kW MF/HF ATU for GMDSS Coast Station
The KTU-2052-1000 Automatic Antenna Tuning Unit (ATU) is a professional coupler, which can operate on a whip or a wire antenna configuration in the RF band 1.65MHz to 30MHz to a 50Ω transmitter (the KTX-2012-1000 for instance).
The KTU-2052-1000 is integrated inside an IP65 large plastic resistant to temperature.
The KTU-2052-1000 is connected to the transmitter through a coaxial cable, a power cable and a shielded control cable.
Maximum RF power input is 1000W PEP.
The coupler network configuration is a PI or L type; sensors continually monitor the state of the tuning and relay this information to the processor.
KENTA can also provide the antenna on-demand.
