Eddystone XE70 – 70 Watt FM Exciter/Transmitter

Eddystone XE70 is an advanced 10–70 W FM broadcast exciter and low power transmitter, combining an ultra-linear modulator, wideband MPX input, LCD metering and full VSWR and temperature protection in a compact rack unit for reliable daily operation.

Eddystone XE70

Eddystone XE70 is a fully featured 70 Watt FM exciter/transmitter designed for professional broadcasters who need clean audio, accurate power control and strong protection in a single compact unit. It can operate as a stand-alone low power transmitter for local coverage or as a high quality exciter driving larger amplifier stages in modular systems. Eddystone XE70 is aimed at community and regional FM stations, backup transmitter chains and engineering teams who want a reliable 70 W platform with straightforward front-panel operation and clear LCD status information.

Performance and key features

Eddystone XE70 delivers adjustable RF output typically from 10 W up to 70 W, allowing engineers to optimise power for coverage or PA drive without external attenuators. The ultra-linear modulator and wideband MPX input maintain excellent baseband performance, preserving stereo separation and RDS injection from modern audio processors. Integrated VSWR, over-temperature and over-current protection continuously supervise operating conditions, with automatic power reduction or shutdown to safeguard the transmitter and antenna system. Eddystone XE70 also uses a stable synthesized oscillator and low-noise RF chain to keep carrier stability and spectral purity within tight broadcast limits.

Main specifications

  • RF output power: adjustable 10–70 W nominal.
  • Frequency range: 87.5–108 MHz FM band with fine tuning steps.
  • Input: wideband MPX/composite plus optional audio inputs.
  • Protection: VSWR, over-temperature and over-current with automatic power control.
  • Form factor: compact rack-mount chassis with front-panel LCD metering and controls.
  • Mains: wide-range AC power input for flexible site deployment.

Applications and integration

Eddystone XE70 suits primary low power FM services, main-site exciters feeding larger amplifiers and hot-standby transmitters in critical facilities. Engineers simply rack-mount the unit, connect the MPX or audio feed and route the RF output to the antenna system or PA input, relying on Eddystone XE70 protection and monitoring to keep the service on-air with minimal intervention.
