MTU-160 - Tuning Unit Module (For 160m Band)

The Yaesu MTU-160 is a µ-Tuning unit made for optional internal installation on the FT_DX-9000MP and FT_DX-9000 Contest Transceivers. (Factory installed on the FT_DX-9000D)

When µ-Tuning is engaged, the standard VRF (Variable RF Preselector) system is bypassed, but the fixed Bandpass Filters are still in the received signal path.

The µ-Tuning filters utilize a stack of large 1.1" (28 mm) Ni-Zn Ferrite cores, driven through a silver-plated coil assembly by a precision stepper motor. The resulting high Q (typically over 300) provides a very steep resonance peak near your operating frequency. The peak may be adjusted away from your frequency, for even greater protection from a specific station, and a graphical depiction of the µ-Tune filter alignment appears on the front panel of the transceiver.
