2.5kW EIRP Complete FM Radio Transmitter Broadcasting System

RDS is now included on all stereo transmitters with audio processing. RDS shows your station name and more scrolling across the car radio display.

This RDS is not just ordinary RDS, it is fully programmable dynamic RDS. This means the transmitter can be connected to a PC by a USB cable. The transmitters RDS circuit can be programmed to pick the Artist and Song name from any folder on the PC disk drive. This folder is easy to set up in the DJ playout software, like Zara Studio etc.

2.5kW Maximum FM Transmission Range Chart: Real-World Listener Data

Understanding Typical Broadcast Coverage.

The following range chart is derived from real-world customer reporting, providing a reliable baseline for expected broadcast coverage. This data reflects the typical ranges really ever recorded by stations utilizing this 100kW EIRP system.

• Data Source: Based on average customer reports in some directions.

• Verification: Reports are primarily compiled from direct listener communication (phone, text, WhatsApp, etc.) to radio station programs operated by our customers.

It is important to understand that FM transmission range is very difficult to predict precisely due to numerous influencing variables (e.g., terrain, antenna height, atmospheric conditions, local noise floor). For a detailed breakdown of the factors affecting signal propagation, refer to our dedicated page FM Transmission Range

FM Stereo Audio and Processing: Achieving Loud, Crisp Broadcast Quality

THE SIGNAL FOUNDATION: LOW NOISE AND HIGH STABILITY

The high-quality FM signal begins with the internal Veronica PLL (Phase-Locked Loop) driver, which serves as the 1W Exciter.

• Function: Produces a super low noise and highly stable FM signal.

• Trustworthiness: Using a trusted PLL driver is fundamental to preventing drift and ensuring carrier integrity, a hallmark of professional-grade equipment.

• Resource: More information on this core component can be found in our 1W Exciter (PLL driver)

INTERNAL AUDIO PROCESSING FOR LISTENERS

After the PLL generates the stable carrier, the internal processing boards take over to shape the audio for the best listener experience:

1. Internal Stereo Coder: Generates the FM stereo signal.
2. Internal Audio Processor: Applies dynamic processing (like limiting and compression) to ensure a loud and crisp audio signal on the listener's radio.

PROFESSIONAL FLEXIBILITY: EXTERNAL PROCESSOR INTEGRATION

For expert broadcasters who utilize specialized external equipment, our system offers complete bypass capabilities.

• Integration: If you are an audio professional preferring an external processor (such as Orban, Inovonics, or PC-generated MPX/RDS signals), the system is fully flexible.

• Bypass Capability: The internal limiter, stereo coder, and audio processor boards can be completely disabled.

• Benefit: This flexibility ensures that the signal chain meets the exact, precise specifications and processing signature required by the station's chief engineer.
