The Suono Telecom ESVB1K 1000 Watt FM transmitter is a compact, high-efficiency 1 kW solution for broadcasters needing reliable main or backup coverage in the 87.5–108 MHz band. This transmitter combines direct carrier FM modulation, front-panel control and LAN or IP connectivity in a rugged 3U 19‑inch chassis. Output power is continuously adjustable from low power up to 1000 W, allowing accurate alignment with licensed ERP and antenna system requirements.
The Suono Telecom ESVB1K supports mono and composite MPX operation with optional stereo encoder and RDS modules, so it integrates cleanly with modern audio processors and STL links. High efficiency and a power factor close to 0.95 at 220 VAC help control energy and cooling costs at transmitter sites. Designed for demanding environments, the transmitter operates across a wide temperature range and at high altitudes, making it suitable for remote or mountain‑top installations.
RF power from the ESVB1K is set via a single rotary encoder, with 1 W and 10 W steps for precise commissioning and maintenance. The unit covers 87.5–108 MHz as standard, with options for OIRT and Japanese bands, and feeds a 50 Ω antenna system through an N‑type RF connector. Internal low‑pass and band‑defining filters maintain good spectral purity and support compliance with typical FM emission limits for harmonics and spurious outputs.
To protect the RF chain, the Suono Telecom ESVB1K uses automatic VSWR fold‑back so operation remains safe into moderate mismatch. A high‑stability internal TCXO reference keeps frequency within tight limits over the operating range, holding the carrier accurately on channel. Forward and reflected power, temperature and alarm states are displayed on the front panel and can also be supervised remotely via the integrated web and telemetry interfaces.
The audio section accepts balanced analog left/right, unbalanced composite MPX, AES/EBU digital audio and dedicated SCA or RDS inputs, allowing mono or stereo/MPX chains without external converters. Mono mode offers selectable input impedance with adjustable level and flat response from 30 Hz to 15 kHz, while composite operation provides wideband flatness to 100 kHz with low distortion suitable for modern FM processing. Typical applications include regional and city‑wide coverage, commercial or public service broadcasters and N+1 systems where 1 kW transmitters share antennas and redundancy infrastructure.
For similar power in a stereo/MPX configuration, engineers can look at the
Eurotel ETL1000 1 kW stereo FM transmitter, which adds an integrated stereo encoder and monitoring features. Another option in the same family is the
Nautel VX1 1 kW FM transmitter, providing a different mechanical platform with comparable RF performance. For higher power and future expansion, the
ECRESO FM 1kW AiO 1 kW FM transmitter offers additional headroom while retaining similar control and audio characteristics. To review other power levels and architectures, engineers can explore the full range of
FM Transmitters to design scalable main and standby chains for their network.
