What Eddystone Broadcast does

Eddystone Broadcast Ltd. is a UK-based designer and manufacturer of FM broadcast transmission systems, founded in 1923 (originally as Stratton and Company) and headquartered in Alcester, Warwickshire. Since 2008 the company has operated as a subsidiary of the Interface Group, employing between 11 and 50 staff. Its product range spans modular FM transmitters from 500W to 20kW across the S7600 and S7900 series, FM exciters from 10W to 300W (XE series), standalone power amplifiers (XA series), and remote monitoring and control equipment including the IRMU, E2023 controller, and Guardian DSP audio monitoring system. Technical differentiation rests on hot-pluggable 300W power amplifier modules common across the S7600 range that allow on-air module replacement with minimal power reduction, a patented N-Way RF Power Combining System for high-power configurations, an ultra-linear modulator with precision TCXO, and a fresh-air-tunnel heat dissipation design.

The business serves radio broadcasters and broadcast network operators globally, with named reference customers including Telekom Malaysia, NEC Japan, PSD Jordan, Ancom Malaysia, and KK12 FM. Revenue mechanics are driven by capital equipment sales of transmitters, amplifiers, exciters, and monitoring hardware, supplemented by professional services covering commissioning, training, and turnkey system delivery. Pricing is quote-based and project-specific, consistent with customized enterprise RF deployments rather than standardized product sales.

Go-to-market is direct enterprise sales supported by regional channel partners - Tentrik Sdn Bhd in Malaysia and Broadcast Components in Australia - and reinforced by exhibition presence at IBC (Amsterdam), Broadcast Asia (Singapore), ABU events, SMPTE (Sydney), and CABSAT (Dubai). The company also holds the historical milestone of supplying the world's first DAB transmitter network to the BBC in 1997. Financials are not publicly disclosed, and revenue, growth rate, and headcount trends since 2019 are not stated in available materials.
