Page 19FT-410 OperaTiOn ManualcOnvenience FeaTures AGc (tool for comfortAble ANd effective receptioN)The AGC system is designed to help compensate for fading and other propagation effects, with characteristics that can be of particular value on each operating mode. The basic objective of AGC is to maintain a constant audio output level once a certain minimum threshold of signal strength is achieved.Press the [AGC] button repeatedly to select the desired receiver-recovery time constant. For most operations, we recommend the “AUTO” mode. 14.195.000M-012[AGC] buttonBlock DiagramAuto Sets the receiver-recovery time automati-cally depending on the operating mode. Fast Sets the receiver-recovery time to fast. This mode is suitable for CW/DATA recep-tion.Slow Sets the receiver-recovery time to slow. This mode is suitable for SSB/AM recep-tion. nOTe:Normally, the “Auto” selection is satisfactory for most situations, but in the event of operation on a crowded band where you wish to receive a weak signal, you may wish to change the setting (to FAST, for example).A B CShift (iNterfereNce rejectioN)IF Shift allows you to vary the DSP lter passband higher or lower, without changing the pitch of the incoming signal, so as to reduce or eliminate interference. Because the carrier tuning frequency is not varied, there is no need to re-tune the operating frequency when eliminating the interference.Rotate the [SHIFT] knob to the left or right to reduce the interference.Referring to Figure “A”, note the depiction of the IF DSP filter as the thick line, with the [SHIFT] knob in the 12 o’clock position. In Figure “B”, an interfering signal has appeared inside the original passband. In Figure “C”, you can see the effect of rotating the [SHIFT] knob to reduce the interference level by moving the lter passband so that the interference is outside of the passband. 14.195.000M-012[SHIFT] knobApplication for FCC / IC FCC ID: K6620621X50 IC: 511B-20621X50
Page 20 FT-410 OperaTiOn ManualcOnvenience FeaTuresrf GAiNThe RF Gain controls provide manual adjustment of the gain levels for the receiver RF and IF stages, to compensate for noise and/or signal strength conditions at the moment.The [RF/SQL] knob should, initially, be rotated to the fully clockwise position. This is the point of maximum sensitivity, and counter-clockwise rotation will gradually reduce the system gain.advice: As the [RF/SQL] knob is rotated counterclockwise to reduce the gain, the S-meter reading will rise.  Rotating the [RF/SQL] knob control to the fully counter-clockwise position will essentially disable the receiver, as the gain will be greatly reduced. In this case, the S-meter will appear to be “pegged”. (That is a full-scale reading). 14.195.000M-012[RF/SQL] knobApplication for FCC / IC FCC ID: K6620621X50 IC: 511B-20621X50
