1 PANEL DESCRIPTION y MICROPHONE CONNECTOR [MIC] Accepts the supplied or optional microphone. • See p. 161 for appropriate microphones. • See p. 23 for microphone connector information. u MIC GAIN CONTROL [MIC GAIN] (p. 36) Adjusts microphone input gain. • The transmit audio tone in SSB, AM and FM modes can be adjusted independently in level set mode. (p. 121) ✔ How to set the microphone gain. Set the [MIC GAIN] control so that the ALC meter occasionally moves up-scale during normal voice transmission in SSB, AM or FM mode. Increases Push Decreases Recommended level for an Icom microphone MIC GAIN i AF CONTROL [AF] (inner control; p. 34) Varies the audio output level of the speaker or headphones. Increases Decreases o RF POWER CONTROL [RF POWER] (p. 36) Continuously varies the RF output power from minimum (2 W*) to maximum (100 W*). *AM mode: 1 W to 30 W Increases max. 100 W Push Decreases min. 2 W (30 W for AM) (1 W for AM) !0 R F GAIN CONTROL/SQUELCH CONTROL [RF/SQL] (outer control; p. 33) Adjusts the RF gain and squelch threshold level. The squelch removes noise output from the speaker (closed condition) when no signal is received. • The squelch is particularly effective for FM. It is also available for other modes. • 12 to 1 o'clock position is recommended for any setting of the [RF/SQL] control. • The control can be set as 'Auto' (RF gain control in SSB, CW, RTTY and PSK; squelch control in AM and FM) or squelch control (RF gain is fixed at maximum) in set mode as follows. (p. 128) MODE SSB, CW RTTY/PSK AM, FM SET MODE SETTING AUTO SQL RF GAIN + SQL RF GAIN SQL RF GAIN + SQL SQL SQL RF GAIN + SQL • When setting as RF gain/squelch control Noise squelch (FM mode) Squelch is open. Recommended level Maximum RF gain RF gain adjustable range S-meter squelch • When functioning as RF gain control (Squelch is fixed open; SSB, CW, RTTY and PSK only) Adjustable range Minimum RF gain Maximum RF gain • When functioning as squelch control (RF gain is fixed at maximum.) Noise squelch (FM mode) Noise squelch threshold (FM mode) S-meter squelch threshold Squelch is open. S-meter squelch Shallow Deep While rotating the RF gain control, noise may be heard. This comes from the DSP unit and does not indicate an equipment malfunction. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21
