Using the Digital Twin PBT

SSB, CW, FSK and AM modes

The Digital Twin PBT (Passband Tuning) electronically

narrows the IF passband width by over wrapping the

passband frequency ranges of 2 PBT ﬁlters (PBT1

and PBT2), to reject interference. The IC-R8600 uses

DSP for the PBT function.

1. Push

Touch [PBT1] or [PBT2].

3. Rotate

to adjust the passband width.

•

The current passband width (BW) and shift frequency

(SFT) is displayed.

A dot is displayed right below the shift frequency

indicates that the passband frequency is shifted.

•

To narrow the IF passband width, rotate

shift the passband width in the opposite direction from

each other.

•

To shift the pass band frequency range, match both

the [PBT1] and [PBT2].

•

The PBT is adjustable in 50 Hz steps in the SSB, CW,

and FSK modes, and 200 Hz in the AM mode. In this

case, the center shift frequency changes in 25 Hz

steps in the SSB, CW, and FSK modes, and 100 Hz in

the AM mode.

•

Touch [PBT1] or [PBT2] for 1 second to clear the PBT

setting.

4. Push

EXIT

to close the setting menu.

NOTE

While adjusting,

you

may hear noise. This comes

from the DSP unit and does not indicate an equipment

malfunction.

IP Plus function

The IP Plus function improves the Intermodulation

Distortion (IMD) quality by optimizing the direct

sampling system performance.

This function optimizes the Analog/Digital Converter

(ADC) against the distortion when you receive a

strong input signals. It also improves the Third-order

Intercept Point (IP3) while minimizing the reduction of

the receive sensitivity.

Each band memorizes the ON/OFF setting.

Touch [IP+] on the

FUNCTION screen

Each touch turns the IP Plus function ON or OFF.

Select ON to prioritize the IP quality, and select OFF

to prioritize the receive sensitivity.

Notch Filter

The notch ﬁlter suppresses interference.

Auto Notch automatically attenuates beat tones,

tuning signals and so on.

The Manual Notch attenuates beat tones, tuning

signals and so on by adjusting the notching width and

frequency.

Auto Notch:

Used in the SSB, AM and FM modes.

Manual Notch:

Used in the SSB, CW, FSK and AM

modes.

Touch [NOTCH] on the FUNCTION screen.

•

Each touch changes between “AN (Auto Notch),” “MN

(Manual Notch)” and OFF.

In the CW or FSK mode, only Manual Notch (MN)

can be selected.

In the FM or DIGITAL mode, only Auto Notch (AN)

can be selected.

Setting the notching width and frequency

Touch [NOTCH] for 1 second.

The Notch setting menu is displayed.

2. Slowly rotate

to adjust the notching

frequency on the POSITION scale.

Touch [WIDTH] to select the Manual Notch filter

width from “WIDE,” “MID” or “NAR.”

NOTE

: While adjusting, noise may be heard.

This comes from the DSP unit and does not indicate

an equipment malfunction.

A dot is displayed

when the ﬁlter

frequency is shifted.
