84 FT-847 OPERATING MANUALMENU SELECTION DETAILSMenu System1 [DIMMER]Function: Setting of the front panel display’sillumination level.Available Values: 0 (Bright) ~ 7 (Dim)Default Setting: 0 (Brightest setting)2 [MIN-FREQ]Function: Setting of the minimum synthe-sizer step size for the MAIN VFOTuning Dial.Available Values: 0.1/1/10 HzDefault Setting: 1 Hz3 [SSB-CH]Function: Setting of the synthesizer steps inthe SSB mode when using theMEM/VFO CH knob.Available Values: 1.0/2.5/5.0 kHzDefault Setting: 2.5 kHzThe MEM/VFO CH knob is extremely useful for mak-ing quick frequency excursions. The 5 kHz setting maybe useful for situations when you ask a station to move“5 kHz UP” for a contact, while the 1 kHz setting isuseful for precise tuning of SSB signals. This settingmay be performed individually on HF, 50 MHz, 144MHz, and 430 MHz.4 [AM-CH]Function: Setting of the synthesizer steps inthe AM mode when using theMEM/VFO CH knob.Available Values: 2.5/5.0/9.0/10.0/12.5/25.0 kHzDefault Setting: 5.0 kHzThe 9.0 kHz setting may be useful for channel-by-chan-nel tuning of AM broadcast stations. This setting maybe performed individually on HF, 50 MHz, 144 MHz,and 430 MHz.5 [FM-CH]Function: Setting of the synthesizer steps inthe FM mode when using theMEM/VFO CH knob.Available Values: 5/6.25/10/12.5/15/20/25 kHzDefault Setting: HF: 5 kHzVHF/UHF: Depends on trans-ceiver version (U.S.A., European, etc.)This setting may be performed individually on HF, 50MHz, 144 MHz, and 430 MHz.6 [CW-PITCH]Function: Setting of the pitch of the CWsidetone, CW Spot, BFO offset,and IF/DSP CW filter center fre-quencies.Available Values: 400 ~ 1100 HzDefault Setting: 700 HzThe CW sidetone frequency corresponds to the toneof your signal as heard by another station. Align theother station’s tone pitch to be the same as your CWsidetone pitch, using the “SPOT” feature, to “zero-beat”to the other station. The CW Pitch alignment may beperformed in 50 Hz increments.7 [WEIGHT]Function: Setting of the radio between CWDashes and Dots for the internalelectronic keyer.Available Values: (Dot:Dash Ratio) 3.0:1 ~ 4.4:1Default Setting: 3.0:18 [SIDETONE]Function: Setting the volume of the CWSidetone.Available Values: 0 ~ 63 (arbitrary scale)Default Setting: 32This CW Sidetone Level adjustment is fixed via thisMenu item, and does not depend on the setting of theAF (GAIN) control.9 [CW-DELAY]Function: Setting the receiver recovery timeduring pseudo-“VOX” CW semi-break-in operation.Available Values: 10 ~ 300 ms.Default Setting: 100 ms.The recovery time may be adjusted in steps of 10 ms.A longer delay may be preferable if you pause fre-quently while sending.
