The programmable FTR-200 is a miniature airborne flight termination receiver and tone decoder for flight termination system applications that utilized tone-based command messaging. FTR-200 provides a highly sensitive superheterodyne RF receiver whose center frequency is programmable. The versatile tone decoder can be programmed to decode 3 or 4 tone sequences, as well as the tone frequencies, and provides command outputs for flight termination devices. The FTR-200 can be enabled for full fail-safe operation, including programmable loss of tone duration.
