1 PANEL DESCRIPTION i RF POWER CONTROL [RF PWR] (p. 3-12) Continuously varies the RF output power from minimum (5 W*) to maximum (200 W*). *AM mode: 5 W to 50 W Increases Decreases o MIC GAIN CONTROL [MIC] Adjusts microphone input gain. • The transmit audio tone in SSB, AM and FM modes can be adjusted independently in set mode. (p. 12-4) ✔ How to set the microphone gain. Set the [MIC] control so that the ALC meter sometimes swings during normal voice transmission in SSB, AM or FM mode. Recommended level for an Icom microphone Decreases Increases !0 VOX/BREAK-IN SWITCH [VOX/BK-IN] ➥ Push to turn the VOX function ON and OFF during SSB, AM and FM mode operation. (p. 6-2) ➥ Push to turn the break-in function ON (semi-breakin, full-break-in) and OFF during CW mode operation. (p. 6-3) ➥ Push for 1 sec. to enter VOX set mode. (p. 6-2) ✔ What is the VOX function? The VOX function (voice operated transmission) starts transmission without pushing the transmit switch or PTT switch when you speak into the microphone; then, automatically returns to receive when you stop speaking. ✔ What is the break-in function? The break-in function switches transmit and receive with CW keying. Full break-in (QSK) can monitor the receive signal during keying. !1 ELECTRONIC CW KEYER SPEED CONTROL [KEY SPEED] (p. 4-4) Adjusts the internal electronic CW keyer's speed. • 6 wpm (min.) to 60 wpm (max.) can be set. Min. 6 wpm Max. 60 wpm !2 BREAK-IN DELAY CONTROL [DELAY] (p. 6-3) Adjusts the transmit-to-receive switching delay time for CW semi-break-in operations. Short delay for high speed keying Long delay for slow speed keying !3 MONITOR SWITCH [MONI] (p. 6-4) Monitors your transmitted IF signal. • The CW sidetone functions regardless of [MONI] switch setting in CW mode. • The [MONI] indicator above this switch lights green while the function is activated. !4 MEMORY CARD SLOT [CF CARD] (p. 2-3) Insert the supplied CF (Compact Flash) memory card for both reading/storing a wide variety of the transceiver's information and data. • The indicator beside the slot lights or blinks when the transceiver reads or writes to the memory card. • Push the eject button to remove the memory card. !5 MONITOR GAIN CONTROL [MONI GAIN] (p. 6-4) Adjusts the transmit IF signal monitor level. Push Monitor gain decreases Monitor gain increases !6 COMPRESSION LEVEL CONTROL [COMP] (p. 6-5) Adjusts the speech compression level in SSB. Push Compression gain decreases Compression gain increases !7 DRIVE GAIN CONTROL [DRIVE] (p. 3-13) Adjusts the transmitter level at the driver stage. Activate in all modes (except SSB with [COMP] OFF). Push Decreases Increases !8 VOX GAIN CONTROL [VOX GAIN] (p. 6-2) Adjusts the transmit/receive switching threshold level for VOX operation. Push Low sensitivity High sensitivity 1-3
