The STXe FM exciter series is designed to provide a cost effective solution for FM broadcast.
Every STXe exciter is tested at the factory for quality and reliability. Technicians will use settings given

default settings are used:
• Frequency – 98.5 MHz
• Operating Mode – FM Only
• Total Output Power – Set to model name (1 kW Model - 1000 W, etc.)
• Emergency Output Power – 0 W

keeping time and reset to 2000-01-01 00:00:00 when the system has no AC power for
a few days. This is highly likely when the exciter is shipped.
