y MICROPHONE CONNECTOR [MIC]
Accepts the suppled or an optonal mcrophone.
• See p. 161 for approprate mcrophones.
• See p. 23 for mcrophone connector nformaton.
u MIC GAIN CONTROL [MIC GAIN] (p. 36)
Adjusts the mcrophone gan.
• The transmt audo tone n the SSB, AM and FM modes
can be adjusted ndependently n the level set mode.
(p. 121)
✔ How to set the microphone gain.
Set the [MIC GAIN] control so that the ALC meter
swngs wthn the ALC range durng normal voce
level transmsson, n the SSB or AM modes. (The
ALC meter must be selected.)

PANEL DESCRIPTION
!0 RF GAIN CONTROL/SQUELCH CONTROL
[RF/SQL] (outer control; p. 33)
Adjusts the RF gan and squelch threshold level.
The squelch removes nose output from the speaker
(closed condton) when no sgnal s receved.
• The squelch s partcularly effectve for FM. It s also
avalable for other modes.
• The 12 to 1 o'clock poston s recommended for the
most effectve use of the [RF/SQL] control.
• The control can be set as 'Auto' (RF gan control n
SSB, CW, RTTY and PSK; squelch control n AM and
FM) or squelch control (RF gan s fxed at maxmum)
n the set mode as follows. (p. 128)
