1.1 Your Transmitter Package
The FM10000 is a highly efficient transmitter package designed to set a new standard
in FM transmitter design offering modularity, ease of use, and long-term reliabil-
ity. The FM10000 package has five (5) PA2000-10K amplifiers, three (3) 5,600 watt
power supplies, a transmitter controller, a low pass filter and an optional FM250.
The FM10000 transmitter package requires no tuning and typically provides 80% RF
efficiency. The three (3) 5600W power supplies are power factor corrected and
90% efficient. Modern MOSFET technology ensures high AC to RF efficiency
(better than 70% overall typical) and long-term reliability. The unmatched efficiency
of this transmitter significantly improves your bottom line by providing cooler
operation and lower power costs.
These modular units are uniquely designed to be compact for convenient shipping
and simple installation with minimal floor space. Installation is easy with three
connections; AC power in, Audio in, and antenna out. In addition, built in metering
and status indicator capabilities enable intuitive operation to further augment
the user-friendly design.
Economic long-term reliability is ensured through our carefully engineered solid-
state design. Each PA2000 features four field-replaceable 500–watt power modules.
This transmitter delivers 2500 to over 10000 watts of RF power output. Use your
existing exciter or purchase the FM10000T which includes our award-winning FM250
exciter for an unbeatable 10 kW transmitter package.
