FT-950

Operating Manual

CONTOUR Filter (See page ??)

The DSP Contour filter is a unique capability providing either nulling or peaking of tunable segments of the receiver passband, so as to suppress interference or excessive frequency components on an incoming signal, or to peak those tunable frequency segments. The amount of nulling/peaking, and the bandwidth over which it is applied, are adjustable via the Menu.

IF SHIFT (See page ??)

The passband center frequency response of the IF DSP filtering may be adjusted using this control.

IF WIDTH (See page ??)

The width of the IF DSP filtering may be adjusted using this control.

IF NOTCH (See page ??)

The IF Notch filter is a high-Q notch filter that can significantly reduce, if not eliminate, an interfering carrier.

DNF (Digital Notch filter) (See page ??)

When multiple interfering carriers are encountered during reception, the Digital Notch Filter can significantly reduce the level of these signals.

DNR (Digital Noise Reduction) (See page ??)

The DSP’s Digital Noise Reduction (DNR) feature utilizes sixteen different mathematical algorithms to analyze and suppress different noise profiles encountered on the HF/50 MHz bands. Choose the selection that provides the best noise suppression, which concurrently will allow the signal to rise up out of the noise.

AGC (See page ??)

The AGC system is highly adaptable to changing signal and fading characteristics, making reception possible under the most difficult conditions.

ATT

When extremely strong local signals or high noise can still degrade reception, you can use the [ATT] button to insert 6, 12, or 18-dB of RF attenuation in front of the RF amplifier.
