FM1050ES Transmitter

Our ES Series transmitters offer output powers from 50 watts to 1200 watts. Our lowest power transmitter, the FM50ES is a perfect solution for those breaking into FM broadcasting on a small-scale. Whether you are setting up a new radio station for a church, a school, or non-profit, this unit will help you get on the air quickly and cost effectively.

The ES Series can be used as a stand alone transmitter or translator. All models have front panel programmable FSK ID. They are perfect for small markets as a main analog transmitter, as well as for LPFM applications and can also be used as an emergency or back up at the largest stations.

Meets or exceeds all FCC standards**. The FM150ES and FM300ES are FCC type certified for use on LPFM stations.

GammaTransmitter

The Gamma FM Series achieves up to a maximum of 80% efficiency with LDMOS based amplifiers. This results in a low cost of ownership. There is also additional cost savings resulting from the lower heat generation of these amplifiers. Less power being lost to generated heat requires reduced power requirement by HVAC systems to cool the transmitter building. The electric power savings in this new PTEK design is significant.

1000 watt power amplifier modules keep the GAMMA reliable and coupled with the hot pluggable power supplies ensures you stay on air.

TRANSMITTER REMOTE CONTROL
The full line of CW Broadcast transmitters include a complete remote control interface (for external remote controls) on the rear D-25 connector. The RC interface includes basic operational analog I/O such as primary metering along with GPI inputs for On/Off and Raise/Lower. Serial commands and serial data outputs are also available on the D-25. Simple serial commands can be entered via a terminal program for basic transmitter commands. Additionally, CW Broadcast offers an inexpensive line of internal and external Web-based network remote controls (see below) to enhance your control and monitoring capabilities.
