Note:  This new module will only fit in the front position of the Yaesu FT-817/818.  If you have extra filters installed in your radio then you cannot fit the NEDSP1901-KBD module inside your radio.  In this case might consider the new compact NES10-2MK4 DSP noise cancelling speaker 

The NEDSP1901-KBD is a direct replacement for the very popular discontinued NEDSP1061-KBD. The NEDSP1901-KBD module incorporates the latest bhi DSP noise cancelling technology and provides up to 40dB of noise cancellation to greatly improve noisy speech signals. The module is controlled by a single pushbutton with LED and audible indication for ease of use. It is supplied as pre-wired retrofit style module and can be integrated directly into the low level audio path of your receiver, transceiver or audio system, giving you excellent DSP noise cancellation and greatly improved speech quality. TThe module features DSP on/off and up to 8 levels of DSP filtering via a small pushbutton interface board. The module is supplied with a fitting kit and general installation instructions plus specific fitting guides for the Yaesu FT-817, Kenwood TS-50 and Icom 706 MK II G. There are also 3rd party instructions available in the "Amateur Radio Installs" section for the Yaesu FT-847, FT-897, FRG100, Realistic DX-394, Alinco DX-77 and the Kenwood TS440. Other radios can also benefit from this module and.  contact us for more information.  The module can also be used to enable a quick evaluation of the noise cancelling properties for commercial applications when considering the basic NEDSP1901-PCB module.  This DSP noise cancelling module works across the whole audio bandwidth and is able to separate the speech signals from the noise giving you excellent processed audio depending on which filter level you require.

Installation information: Just four wires are used to connect the module in circuit: Audio In, Audio out, 0V and Power. All that's left to do is drill holes to accommodate the switch assembly and label. Fitting kit supplied.
