The FMTX250 is a fully integrated 125W Stereo FM broadcast system
with audio processing, stereo encoder and RDS encoder in a single,
highly compact product.
The audio processor provides intelligent Automatic Gain Control, multi-
band compressor/limiters, plus clipping and DSP 15KHz filtering.
The FMTX250 also boasts a high quality Stereo Encoder section, for
perfect audio separation and detail.
The integral RDS encoder uses direct digital waveform synthesis for
clean, perfect
generation of the 57kHz subcarrier. As well as PS (station
name) information, extended features - including RadioTEXT,
Alternative Frequency and Traffic Announcement content - are also
broadcast. Being standalone, a dedicated computer or data feed are
not required. Periodic content updates are easily performed via the
transmitter’s USB port, using a Windows™ Laptop or PC. Free software
is available at https://lucorobroadcast.com/support
At the heart of the FMTX250 is a high quality PLL modulator, and the RF
Power Amplifier uses the latest high-gain Enhancement Mode MOSFET
device, achieving new levels of efficiency and reliability.
TTL remote monitoring and switching allows the FMTX250 to be easily
integrated into automated back-up applications. An audio silence
alarm, plus remote RDS TA control are also provided.
