TELE SUPPLY发射器JTM-30C介绍
JTM-30C 型 NDB 发射机是一款非定向无线电信标 (NDB) 发射机，设计用于石油钻井平台和船舶上的船载使用，以及其他应用。
JTM-30C 提供两种不同的射频功率输出版本（100W PEP 或 200W PEP），可配置为单 NDB 发射机，配备一条完整的发射链路，或作为双 NDB（或冗余）发射机，具有两条完整的发射链，具备故障检测/报告和自动切换功能，共用天线调谐。
发射机阻抗匹配天线阻抗需要手动调谐。自动调谐单元为选配功能。该设备基于全新的NDB发射机理念，采用数字激励器。发射机具有以下主要特性。
JTM-30C 确实是一款一体化单元，包含天线调谐电路、激励器（用于产生输出信号）、射频功率放大器以及控制和监控电路。交流电源和直流电源也可安装在 IP66防护等级的防风雨加固型发射机机柜内。
柜体内部安装有加热元件，用于在低温下降低湿度。
NDB Transmitter Type JTM-30C is a Non-Directional Radio Beacon (NDB) Transmitter designed for onboard use on oilrigs and ships, as well as for other applications.
The JTM-30C is available in two different RF Power output versions (100W PEP or 200W PEP) as Single NDB Transmitter configuration with one complete transmit chain, or as
Dual NDB (or Redundant) Transmitter with two complete transmit chains with fault detection/reporting and automatic changeover, common Antenna Tune.
Transmitter tuning to match the antenna impedance is a manual procedure. Auto Tune Unit is offered as an option. The equipment is built upon a totally new concept for NDB transmitters utilizing digital Exciters. The transmitters have the following main features
JTM-30C is indeed an ALL-IN-ONE unit consisting Antenna Tuning Circuits, Exciter(s) (generating the output signal), RF Power Amplifier(s) and Control & Monitoring circuits. The AC Mains & DC Power Supply may also be installed inside the IP66 weatherproofed and ruggedized Transmitter cabinet.
A heater element is installed inside the cabinet to reduce humidity at low temperature.
