Overview

Designed for reliability and longevity, the modular design of the Ecreso FM 3500W Transmitter is based on the ECRESO FM 1500W/2000W Amplifier module.

This amplifier delivers the best cost/watt ratio over the lifetime of the transmitter, has the lowest heat dissipation available on the market today and, with a maximum output power of 3800W, it provides a comfortable margin over nominal power. 

A crystal-clear signal is achieved using the ECRESO FM 100W exciter and its direct to channel digital modulator and the system can be fully controlled and monitored through the built-in Web interface and SNMP protocol.
