28 FT-817 Operating ManualSSB T RANSMISSIONBasic Setup/Operation1. Press the / key so as to select either SSB (LSB/USB) mode. If youare operating on the 7 MHz or lower bands, select the LSB mode. If you are operating onthe 14 MHz or higher bands, select the USB mode.2. Press the key momentarily, then rotate the knob, as needed, until OperatingFunction Row 9 [PWR, MTR] appears on the display, then press the (MTR) key toselect the “ALC” meter function (“alc” will appear at the right side of the “MTR” icon).3. Press the microphone’s PTT switch, and speak into the microphone in a normal voicewhile watching the meter. The ideal audio input level to the transmitter from the micro-phone will cause a few “segments” of indication on the ALC meter. Release the PTTswitch to return to receive mode.4. If the ALC meter is too high, or too low, you may need to reset the Microphone Gain: Press and hold in the key for one second to enter the Menu mode. Rotate the knob to recall Menu #46 (SSB MIC). Close the PTT switch, and while speaking into the microphone rotate theknob until the proper ALC indication is achieved on voice peaks. When done, press and hold in the key to save the new setting for the Microphone Gain.The [TONE] switch on the back of the MH-31A8J microphone provides adjust-ment of the microphone’s frequency response. Setting this switch to the “2” posi-tion will roll off some of the bass response, resulting in improved “talk power” in manyinstances. The “1” position is primarily used in countries like Japan, where vowel soundsare of critical importance in conveying information; in Western languages, consonantsounds (which are rich in high-frequency components) are frequently more important.Adjusting the Transmitter Power OutputFour power levels are available on the FT-817: 5 Watts, 2.5 Watts, 1 Watt, and 0.5Watt. When using Alkaline batteries or the optional FNB-72 Ni-Cd Battery Pack,the microprocessor, detecting internal battery use, automatically sets the power levelto 2.5 Watts, which appears on the display as “ ”. If you set the power to five watts,the power level icon is the same as for 2.5 Watt operation, but at 5 Watts the icon isblinking. For 0.5 Watt, there is one “bar” to the right of the “L” in the power icon, andfor 1 Watt there are two “bars” displayed.The power level is easy to change:1. Press the key momentarily, then rotate the knob to select OperatingFunction Row 9 [PWR, MTR].2. Press the (PWR) key, as needed, to set the desired power level. The icon willchange, based on the power level you have set.TRANSMITTER O PERATION
