SkyMaster 18-40x80 Zoom Binocular Item #71021
RF -Tuning Kit C 30/20m band for FT-2000 / FTDX-5000 / FT-950
RF -Tuning Kit C 30/20m band for FT-2000 / FTDX-5000 / FT-950

RF -Tuning Kit C 30/20m band with MTU-30/20

-Tune Kits are external filters for the bands 160m, 80 + 40m and 30 + 20m. These filters work with a motor driven coil and achieve a very high Q, again increasing the strong signal handling capabilities of the transceiver. The band filters require some assembly before use. All required cables are included. Size 330 x 120 x 120mm, weight 2.6kg.

Optional Fully-automatic External RF -Tuning - RF -Tuning Kit

The secret of the superior performance of the FT DX 5000/FT-2000 series radios on the lower bands is the RF -Tuning system; the very same system is now available as an option for the FT-950!

On the lower Amateur bands, the signal voltages impinging on a receiver can create noise and intermodulation effects that can cover up weak signals you're trying to pull through. Three modules (MTU-160, MTU-80/40, and MTU-30/20) are available these modules may be connected externally with no internal modification required!

The RF -Tuning filters utilize a stack of large 1.1" 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. (On the 160 m band, typically -3DB@?12 kHz, -30DB@?450 kHz.) And the 3rd order Intercept Point (IP3) is increased by 4 dB with the RF -Tuning system.
The ferrite cores utilized in the RF -Tune filters are driven by a high-resolution, high torque stepper motor (4-phase unipolar motor/2-phase magnetization system) with angular resolution of 1.8deg. The synchro belt drive has an estimated lifetime of more than 10,000 hours of actual operation. For 160-meter operation, the ferrite core diameter is a full 2.2"! The RF -Tune system tracks your operating frequency, although you can chose to manually skew the frequency response when special interference conditions require it.

If you turn the RF -Tune system off when leaving your frequency or QSYing to other bands, the RF -Tune system will be re-centering the RF -Tune filter on your current operating frequency when the RF -Tune is re-engaged.
