You will notice that the S-meter deflection, when µ-Tune is engaged, is slightly less than when it is out of the circuit; this is normal. If your antenna system gain is so low as to make it impossible to hear band noise when µ-Tune is engaged (highly unlikely), just switch it out, which has slightly less insertion loss.
FT-950 Operating Manual VFO-A and VFO-B. On the 10 MHz and lower bands, it generally is not necessary to use any preamplifier at all; selecting the “ON” position described above will increase the strong-signal-handling capability of the receiver, and generally will result in more pleasant reception due to reduced noise. If you can hear band noise with the preamplifiers disengaged, then a preamplifier is generally not needed. R.

FT-950 Operating Manual Advice: ALC meter deflection may be caused by excessive drive power, but also by reflected power detected in the antenna system. If the impedance presented to the transceiver is different from 50 Ohms, ALC meter action may be observed that is not related to the proper setting of the [MIC GAIN] knob. Therefore, we recommend that you make the [MIC GAIN] knob adjustments into a dummy load or antenna system presenting an impedance very close to 50 Ohms.
FT-950 Operating Manual Using the Automatic Antenna Tuner The Automatic Antenna Tuner (hereinafter referred to as the “ATU”) built into each FT-950 is crafted to ensure a 50-Ohm load for the final amplifier stage of the transmitter. We recommend that the ATU be used whenever you operate on the FT-950. Advice: The ATU of the FT-950, being located inside the station, only adjusts the impedance presented to the transceiver at the station end of your coaxial cable feedline.
FT-950 Operating Manual blinking). 4. While tuning around the band using the Main Tuning Dial knob, you will observe that the “TUNER” icon blinks momentarily every 10 kHz. This momentary blinking indicates that a new tuning window has been entered. If you want to save tuning data associated with this 10 kHz window, repeat step 4 (above) for each such window. On bands like 1.8 MHz where the impedance may change rapidly, the storage of a number of tuning points is recommended. 5.
