In addition, the AGC time constants (slow,medium, and fast presets are user selectable)give flexibility and speed needed for work-ing the pile-ups.Įxample forsetting thetime constantfor SSB-Mid,2.0 seconds. Unlike rigswith a single AGC circuit, the AGC in theIC-756PROII will be able to copy weaksignals without the pumping of the AGCfrom stronger adjacent signals. This AGC system isincredibly impressive with the rejection ofunwanted signals or noise. The 32-bit DSP processing power of theIC-756PROII produces real results byseparating a signal component from thenoise with the variable Noise Reduction.By suppressing the noise components, anoutstanding signal-to-noiseratio is achieved, providingclean, clear audio in allmodes without distortion ofthe target signal.Īll would be lost if not for the power of themultiple AGC loops. The automatic notchlocks will eliminate 2 or more interferingsignals simultaneously without signal lossor distortion.

In addition to the filter display, the LCD in-dicates the twin PBT conditions acrossthe top of the screen, so you can still usethe lower portion of the TFT display forother radio operations.Īn incredible 70dB of attenuation is atyour command with the manual notch.Eliminate strong adjacent signals or beattone noise, without reducing the perfor-mance of the AGC gain.Įliminate those annoying AM carriers,amplifier or radio tune up interference witha push of a button. With the digital IF filters,the PBT performance allows you to cutaway all the interference and noise tohear the actual signal. By broadening the filterskirt, the characteris-tics of the soft filter per-forms much like amechanical filter with-out the ringing.īy moving the IF pass band, the digitaltwin Pass Band Tuning (PBT), allows theflexibility of both IF shift and narrowing ofthe IF passband.
Running a pile-up has become easier withthe soft CW filter. DX hunters willhave to try this one toreally see the magic ofthe Sharp CW filter.ĬW Soft Filter Digital Filter, AnalogOperation The steep filterform, only 200Hz from 6/60dB, willallow you to pick out a weak signal that isburied by a strongersignal. The too good to be true CW filter! Me-chanical or Crystal filters cannot give youthe weak signal edge of the Sharp CW fil-ter in the IC-756PROII. Although maintainingthe steep filter skirt characteristics of adigital filter, the soft fil-ter increases the signalto noise ratio of the in-tended signal. The perfect filter shape factor when tryingto pick out a weak signal! The rounded fil-ter shape resembles a traditional analogfilter, by rolling off the high and low ends SSB Soft Filter Providing GoodReadability The perfect filter shape factor when signalfidelity or pinpoint accuracy is needed! Asharp slope from the filter edges givesFULL audio response while eliminatingany adjacent interference. SSB Sharp Filter Both for SharpSelectivity and Signal Fidelity Independent SSB and CW Fil-ters give you the flexibility you want whilelistening to the signal. Select an appropriate filter shape, de-pending on your operating style or bandconditions.
