TH-F6A/F7E36ADJUSTMENTC. BPF adjustment1) Display the “BPF” item.2) Select points f1 to f3 as shown in the “FrequencyAdjustment Points” table below.3) Set the display frequency to the frequency appropriateto the frequency adjustment point.4) Turn the encoder to change the “real-time value”.5) Press [MNU] key to set the “real-time value” in theEEPROM.6) Adjust all frequency adjustment points.• Frequency adjustment points• To adjust “AM radio” or “HF” band, the bar antenna mustbe activated (factory default: ON).• If a band does not require adjustment, the followingmessage appears. Operations 4) and 5) are invalid.D. Second local adjustment1) Display the [2nd: 0] item.2) Set the operation band to B band.3) Set display frequency to the adjustment frequency.4) Turn the encoder, change the “real-time value”, andmaximize the receiver volume. (Max. sensitivity)5) Press [MNU] key to set the “real-time value” in theEEPROM.6) Display the [2nd: -25] item.7) Set the measuring equipment frequency to the “displayfrequency -2.5kHz” and perform steps 4) and 5).8) Display the [2nd: +25] item.9) Set the measuring equipment frequency to the “displayfrequency +2.5kHz” and perform steps 4) and 5).• Adjustment in FINE mode.• Adjustment in B band only.• There are only three frequency adjustment points (0, -25and +25).• 433.000BPF : ∗∗ f1 : ∗∗2nd : 83 +25 : FF3120.000Real-time value EEPROM settingFrequency adjustment point3144.000BPF : 83 f1 : FFReal-time value EEPROM settingFrequency adjustment pointBand Frequency adjustment pointA band 144MHz 3 points (f1, f2, f3)220MHz 3 points (f1, f2, f3) K destination onlyOthers No adjustmentB band AM radio 3 points (f1, f2, f3)HF 3 points (f1, f2, f3)50,FM radio 3 points (f1, f2, f3)118,144 3 points (f1, f2, f3)TV-V,200Others No adjustment• If the operation band is A band, no adjustment is required,and the following message appears.

SSB BFO adjustmentNote: You do not need to adjust [BFO: SW].1) Display the [BFO: LS] item.2) Set demodulation mode to LSB.3) Turn the encoder, change the “real-time value”, and setthe detection frequency to 1 kHz.4) Press [MNU] key to set the “real-time value” in theEEPROM.5) Display the [BFO: US] item.6) Set demodulation mode to USB.7) Turn the encoder, change the “real-time value”, and setthe detection frequency to 1 kHz.8) Press [MNU] key to set the “real-time value” in theEEPROM.• Adjustment in B band only• There are only two adjustment points (LS and US).• If the operation band is A band, no adjustment is requiredand the following message appears. Operations 3), 4), 7)and 8) are invalid.F. Squelch adjustment1) Display the [SQ: 1] item.2) Set the display frequency and demodulation mode asshown in the “Frequency/Mode Adjustment Points”table below.3) Press [MNU] key to set the “real-time value” in theEEPROM as a threshold value.4) Display the [SQ: 2] item.5) Press [MNU] key to set the “real-time value” in theEEPROM as a level 2 value.6) Adjust all frequency/mode adjustment points.• 144.0002nd : ∗∗ +25 : ∗∗BFO : 83 CW : FF3120.000Real-time value EEPROM settingAdjustment point3144.000BPF : ∗∗ CW : ∗∗3144.000SQ : 83 1 : FFReal-time value EEPROM settingAdjustment point
