On-site transmitter engineering for high-power AM and FM broadcast facilities. From PA stage tuning and harmonic filter alignment to full site commissioning and emergency troubleshooting — we keep your transmitter plant on the air.
High-Power AM Transmitter Signal Chain
We work on the full signal chain — from exciter through PA stage, harmonic filter, and transmission line — on both legacy tube-type and modern solid-state platforms.
Full installation and commissioning of new AM and FM transmitters including mechanical installation, AC power wiring coordination, RF plumbing, and initial alignment. We work with all major manufacturers — GatesAir, Nautel, Continental, Harris, and others.
Precision tuning of power amplifier stages for maximum efficiency and output power. We optimize grid/plate loading on tube-type transmitters and module-level performance on solid-state platforms, with full documentation of operating parameters.
Scheduled maintenance programs tailored to your transmitter type and power class. Includes capacitor inspection, cooling system service, RF contact cleaning, interlock verification, and operating parameter documentation to establish performance baselines.
Rapid-response field service for transmitter failures and on-air emergencies. We diagnose and repair tube failures, solid-state module faults, power supply failures, control system malfunctions, and RF component damage — with the goal of restoring service as quickly as possible.
Measurement and alignment of low-pass and bandpass harmonic filters to ensure FCC Part 73 and Part 15 compliance. We use calibrated spectrum analysis to verify harmonic and spurious emission levels and document results for FCC records.
Inspection, testing, and repair of coaxial and rigid transmission line systems including connector inspection, VSWR measurement, pressurization system service, and ice bridge maintenance. We identify and correct impedance mismatches before they become failures.
Maintenance and repair of transmitter cooling systems including forced-air, liquid-cooled, and vapor-phase systems. Proper thermal management is critical to transmitter longevity and reliable high-power operation.
Installation and service of remote control and monitoring systems including legacy analog systems and modern IP-based platforms. We configure alarm thresholds, verify interlock operation, and integrate with station automation systems.
Complete site commissioning for new and relocated transmitter facilities including RF system verification, operating parameter documentation, FCC license compliance confirmation, and operator training.
Decades of hands-on experience across the full range of AM and FM broadcast transmitter platforms — from classic tube-type high-power AM transmitters to current-generation solid-state systems.

Why stations trust us
We work on your schedule — nights, weekends, and around programming to minimize off-air time.
We carry calibrated test equipment: spectrum analyzers, network analyzers, power meters, and oscilloscopes.
We document everything — operating parameters before and after, with written reports you can keep on file.
We understand FCC technical rules and ensure all work maintains license compliance.
