The FK703 wireless microphone has two tuned stages for extra stability and gain. Construction is simplified by adoption of etched resonant coils on the PCB.
Its small outline lends itself to use as a lapel microphone or security “bug”.
The FK703 may be used with any FM radio receiver in public address situations.
