The Eddystone 150W FM transmitter FM150 is a highly advanced, fully featured broadcast FM exciter that is also ideally suited for use as a low power stand alone transmitter.

Use of wideband design techniques means that frequency setting is easily achieved by internally set, direct reading dial switches - no further tuning is required.

The FM150 uses the sbs ultra linear modulator to give superb sound reproduction with freedom from overshoots and artefacts.

The Eddystone 150W FM Transmitter FM150 will operate into any load without damage thanks to its VSWR cutback circuit that protects the power amplifier stage from adverse operating conditions, says Richardson Electronics .

The PA Section in the FM150 uses sbs’ world renowned heat dissipating “fresh-air-tunnel” concept. The fan provides cooling to the specially designed heat sink with a stream of air that needs no filtering, saving on routine filter replacements.

The Eddystone FM Transmitter FM150 front panel metering shows forward and reflected power together with internal voltages, temperature and the modulation level. Quick view LED’s show advanced status information, including CPU ok, PLL Lock, external standard presence, mute, forward power alarm, receive carrier alarm (when used with rebroadcast option), modulation alarm and temperature. Also shown are the PA outputs including, forward, reverse, temperature and CPU status.

The addition of the unique modulation alarm, gives broadcasters alarm status outputs and indications that will show loss of audio or over modulation. A front panel monitor point for RF output is provided, as is a fully buffered baseband monitor for accurate monitoring of the modulator input.

The rear panel of the Eddystone FM transmitter FM150 includes a remote control/monitoring socket that allows carrier muting and status signalling to an external system, additionally data sockets are provided for use with systems that have the ability to control exciters via RS232 or TCP/IP, these sockets are also used for programming advanced features within the FM150.

The Eddystone FM Transmitter FM150 is fully compatible with N+1 systems, with remote frequency selection being achieved by either RS232/TCPIP interface or rear panel logic selection of up to 6 preset frequencies. Very conservatively rated components and a switch mode rectifier are used to ensure extremely high reliability and to give good efficiency.
