1 PANEL DESCRIPTION @2 E LECTRONIC CW KEYER SPEED CONTROL [KEY SPEED] (p. 49) (Mode: CW) Rotate to adjust the keying speed of the internal electronic CW keyer to between 6 wpm (minimum) and 48 wpm (maximum). Slow Fast @3 P REAMP•ATTENUATOR SWITCH [P.AMP•ATT] PREAMP SWITCH Operation (p. 71) (Frequency band: HF/50 MHz) ➥ Push to select one of two receive RF preamplifiers, or to bypass them. • "P. AMP " is a wide dynamic range preamplifier. It is most effective for the 1.8 to 21 MHz bands. • "P. AMP " is a high-gain preamplifier. It is most effective for the 24 to 50 MHz bands. • No indicator appears when the preamplifiers are not selected. (Frequency band: 144/430/1200 MHz) ➥ Push to turn an optional AG-25, AG-35 or AG1200* preamplifier unit ON or OFF, if installed. • "P.AMP" appears when the preamplifier unit is ON. *AG-1200 has been discontinued, but it can be still be used. ✔ What is the preamplifier? The preamplifier amplifies signals in the front end to improve the S/N ratio and sensitivity. Select "P. AMP " or "P. AMP " when receiving weak signals. ATTENUATOR SWITCH Operation (p. 71) ➥ Hold down for 1 second to turn ON the attenua- tor. • "ATT" appears when the attenuator is ON. ➥ Push to turn OFF the attenuator. • "ATT" disappears. ✔ What is the attenuator? The attenuator prevents a desired signal from being distorted when very strong signals are near it, or when very strong electromagnetic fields, such as from a broadcasting station, are near your location. @4 NOISE BLANKER SWITCH [NB] (p. 76) ➥ P ush to turn the noise blanker ON or OFF. The noise blanker reduces pulse-type noise such as that generated by vehicle ignition systems. The noise blanker is not effective for non-pulse-type noise. • "NB" appears when the noise blanker is ON. ➥ Hold down for 1 second to display the "NB" screen. Push to return to the previous screen display. @5 VOX/BK-IN SWITCH [VOX/BK-IN] VOX SWITCH Operation (p. 78) (Mode: SSB/AM/FM/DV) ➥ Push to turn the VOX function ON or OFF. ➥ Hold down for 1 second to display the "VOX" screen. Push to return to the previous screen display. ✔ What is the VOX function? The VOX function (voice operated transmission) automatically starts transmission when you speak into the microphone; then automatically returns to receive when you stop speaking. BK-IN SWITCH Operation (p. 79) (Mode: CW) ➥ Push to toggle the break-in operation between semi break-in and full break-in, or to turn OFF the break-in function. ➥ Hold down for 1 second to display the "BKIN" screen (Break-in). Push to return to the previous screen display. ✔ What is the break-in function? The break-in function automatically switches between transmit and receive with your CW keying. Using Full break-in function (QSK), you can hear the receive frequency in-between keying. @6 MONITOR SWITCH [MONITOR] (p. 81) ➥ Push to turn the Monitor function ON or OFF to listen to your own transmitted audio. • "MONI" appears when this function is ON. • In CW mode, the CW sidetone can be heard, regardless of the [MONITOR] switch setting. ➥ Hold down for 1 second to display the "MONI" screen (Monitor) to set the monitor level. Push to return to the previous screen display. @7 CALL•GPS SWITCH [CALL•GPS] CALL SWITCH Operation (p. 139) Push to select the call channel. GPS SWITCH Operation (p. 121) Hold down for 1 second to display the "GPS" screen. Push to return to the previous screen display. @8 FUNCTION SWITCHES [F1]-[F5] Push to select the function which is indicated on the LCD display above each switch. (p. 19) • T he functions vary, depending on the selected menu and the operating mode. The optional UX-9100 is required for 1200 MHz frequency band operation. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 4
