5 ASSISTING YOUR SMOOTH QSO AGC (AUTOMATIC GAIN CONTROL) AGC is a function that automatically controls the IF Gain so as to absorb variations in the received signal strength. Following the receiving state or the operating mode (other than FM mode), FAST, MID, or SLOW can be configured for the AGC time constant. The digital AGC circuit of the transceiver is adjustable to a SLOW, MID, or FAST value ranging from "1" (the quickest) to "20" (the slowest). In general, a fast time constant is configured for CW and FSK modes where there is a rapid variation in the received signal strength, and a slow time constant is configured for SSB and AM mode where the variation is slower. Fast time constant is effective for quick tuning when a weak signal is present. Also, you can disable the AGC. As shown below, a default AGC time constant is set on a mode-by-mode basis. CHANGING THE AGC TIME CONSTANT Time constant for the main band and sub band can be independently changed from the defaults. 1 Press one of the mode keys to select any mode other than FM mode. 2 Press and hold [AGC/SEL] (M) or [AGC/SEL] (S) to open the AGC screen. ■ Defaults of AGC Time Constant (common to Main Band and Sub Band) Mode Time Constant Display SSB SSB-DATA SLOW SLOW AGC-S CW FAST FSK PSK FAST FAST AGC-F AM AM-DATA SLOW SLOW AGC-S 3 Press [AGC] (F3), [AGC/SEL] (M), or [AGC/SEL] (S) to select "FAST", "MID", or "SLOW". Pressing [AGC] (F3), [AGC/SEL] (M), or [AGC/SEL] (S) while the AGC is disabled for the main band and sub band enables the AGC. SELECTING THE AGC TIME CONSTANT Following are the procedure to switch the AGC time constants of the main band and sub band to "FAST", "MID" or "SLOW". . 1 Press one of mode keys to select any mode other than FM mode. 2 Press [AGC/SEL] (M) or [AGC/SEL] (S) to select the AGC time constant. Each time you press the key, the selection cycles as follows: FAST > MID > SLOW > FAST 4 Press [-] (F4) or [+] (F5), or rotate the MULTI/CH control to select the AGC time constant. • Selecting "1" enables the slowest AGC time constant, and selecting "20" enables the fastest AGC time constant. The defaults of the AGC time constants for each operating modes are below. Mode FAST MID SLOW SSM 9 12 15 SSB-DATA 9 12 14 CW 9 12 14 FSK 7 11 14 PSK 7 11 14 AM 9 13 16 AM-DATA 9 13 16 • Press and hold [(RESET)] (F1) to reset the selected AGC time constant to the default. 5 Press [ESC] to exit. In FM mode, the AGC screen does not open even with a long press of either [AGC/SEL] (M) or [AGC/SEL] (S). 5-4 Index Contents

AGC ±AUTOMATIC GAIN CONTROL²

AGC is a function that automatically controls the IF Gain

so as to absorb variations in the received signal strength.

Following the receiving state or the operating mode (other

than FM mode), FAST, MID, or SLOW can be configured

for the AGC time constant.

The digital AGC circuit of the transceiver is adjustable to a

SLOW, MID, or FAST value ranging from “1” (the quickest)

to “20” (the slowest).

In general, a fast time constant is configured for CW and

FSK modes where there is a rapid variation in the received

signal strength, and a slow time constant is configured for

SSB and AM mode where the variation is slower.

Fast time constant is effective for quick tuning when a

weak signal is present.

Also, you can disable the AGC. As shown below, a default

AGC time constant is set on a mode-by-mode basis.

Press one of mode keys to select any mode other than

FM mode.

Press

[AGC/SEL]

[AGC/SEL]

(S) to select the

AGC time constant.

Each time you press the key, the selection cycles as follows:

FAST > MID > SLOW > FAST

CHANGING THE AGC TIME CONSTANT

Time constant for the main band and sub band can be

independently changed from the defaults.

Press one of the mode keys to select any mode other

than FM mode.

Press and hold

to select "FAST", "MID", or "SLOW".

Pressing

while the AGC is disabled for the main band and sub band

enables the AGC.

Press
