    The FT-950 is designed for use with any antenna system providing a 50 Ohm resistive impedance at the desired operating frequency. While minor excursions from the 50-Ohm specification are of no consequence, if the Standing Wave Ratio (SWR) present at the Antenna jack is greater than 3:1, the transceiver’s Automatic Antenna Tuner may not be able to reduce the impedance mismatch to an acceptable value.

    The FT-950 transceiver, like any other HF communications apparatus, requires an effective ground system for maximum electrical safety and best communications effectiveness. A good ground system can contribute to station efficiency in a number of ways: It can minimize the possibility of electrical shock to the operator. It can minimize RF currents flowing on the shield of the coaxial cable and the chassis of the transceiver;...

    The FT-950 includes a wide range of special features to suppress the many types of interference that may be encountered on the HF bands. However, real world interference conditions are constantly changing, so optimum setting of the controls is somewhat of an art, requiring familiarity with the types of interference and the subtle effects of some of the controls. Therefore, the following information is provided as a general guideline for typical situations, and a starting point for your own experimentation.

    µ-T RF µT The RF µTuning Kit provides ultra-sharp RF selectivity for the front end of the transceiver. Very high Q is made possible by the narrow-band design. Three RF µTuning Kits are available. The MTU-160 covers the 1.8 MHz band. The MTU-80/ 40 covers the 3.5 and 7 MHz bands.

    µ-T RF µT The µ-Tune filters are the most advanced, selective RF preselector filters ever incorporated into an Amateur Radio transceiver. The RF selectivity provided by µ-Tune can be of tremendous value in ensuring quiet, intermod-free recep- tion even in the most crowded bands on a contest weekend. The µ-Tune filters provide RF selectivity on the order of a few dozen kHz at -6 dB, at the expense of a few dB of system gain on bands where noise figure is seldom an issue.

If a very strong interfering carrier is encountered, we recommend you first use the IF NOTCH filter, as it is the most effective notching tool in the receiver section.

    EMORY PERATION Memory channels may be grouped into as many as six convenient batches, for easy identification and selection. For ex- ample, you might want to designate memory groups for AM BC stations, shortwave broadcast stations, contest frequencies, repeater frequencies and PMS limits, or any other groupings you like. Each memory group is capable of holding up to 20 memory channels (except Memory Group 01: it is 19 memory channels, and the Group size is fixed).

    PERATION ON LASKA MERGENCY REQUENCY 5167.5 U.S. V Section 97.401(d) of the regulations governing amateur radio in the United States permit emergency amateur communica- tions on the spot frequency of 5167.5 kHz by stations in (or within 92.6 km of) the state of Alaska. This frequency is only to be used when the immediate safety of human life and/or property are threatened, and is never to be used for routine communications.

    To limit scanning (and manual tuning) within a particular frequency range, you can use the Programmable Memory Scan- ning (PMS) feature, which utilizes nine special-purpose memory pairs (“P1L/P1U” through “P9L/P9U”). The PMS fea- ture is especially useful in helping you to observe any operating sub-band limits, which apply to your Amateur license class. 1.

    FC-40 E The FC-40 makes use of the control circuitry built into the transceiver, which allows the operator to control and monitor automatic operation of the FC-40, which mounts near the antenna feedpoint. The FC-40 uses specially selected, thermally stable components, and is housed in a waterproof case to withstand severe environmental conditions with high reliability. A carefully-chosen combination of solid-state switching components and high-speed relays allows the FC-40 to match a wide variety of antennas to within a 2:1 SWR on any amateur band frequency (160 through 6 meters), typically in less than eight seconds.
