Transmitter
The station’s transmitter site was moved in October 2007. It was formerly located in the old studio, in the east basement of Brady Hall. It was relocated to another location in Brady Hall where it was re-engineered and re-built.
WLSO operates two transmitters. The primary transmitter is a R.V.R. TEX-300-LCD installed in March 2008. The original, now a backup transmitter, consists of a Bext TEX-20-NV exciter and a separate Bext PJ-200 power amplifier.
The station’s antenna system is on the roof of Brady Hall. It is a 2-bay circularly-polarized radiator.
Programming is sent to the transmission site utilizing the Tele-Link Studio Transmitter Link (STL) from Energy-Onix.
WLSO utilizes Sine System’s Remote Facilities Controller (RFC-1) at the transmitter site. It allows for remote and automatic controls, system monitoring and acts as an alarm system calling station engineers immediately in the event of a system fault. WLSO's RFC-1 monitors 24 channels of telemetry and logs all data though GetTelemetry software.
WLSO also uses as an Orban Optimod 8200-FM audio processor connected to a controlling computer at the transmitter. WLSO's air signal is continually monitored by an Inovonics FM modulation analyzer model 531 and received audio is sent back to the studio to be checked.
All equipment is protected through a Polyphazor lighting-arrestor and several back-up power supplies, allowing uninterrupted broadcasts and relaying notifications from the Emergency Alert System (EAS) to the community in the event of a power disruption or other emergency.
