SOTAbeams LASERBEAM-VARI Digital Variable Bandwidth Audio Filter Module
SOTAbeams LASERBEAM-VARI Digital Variable Bandwidth Audio Filter Module - the perfect addition to your project or your existing radio. Unlike analogue filters, digital filters provide near-perfect characteristics. Because of the way that they are implemented, they are better than analogue filters in almost every way! LASERBEAM-VARI Modules been designed for ease of use. One simple control allows you to continuously vary the bandwidth or the center frequency of the filter. All settings produce the same great filters with flat pass bands and steep skirts. Whether you need passband tuning, filters for digital modes and APRS, low pass filters or CW filters, the LASERBEAM-VARI does it all in one compact module. Dial up EXACTLY the filter you need. •Bandwidth 200Hz - 3500Hz •Max Passband 200Hz - 3500Hz •Indicator outputs for tuning mode (bandwidth or center-frequency) •On board overload indicator •User-defined power-up filter settings •Two gain settings Great for all modes: SSB-CW-Digi-AM-NBFM. A single clickable rotary encoder provides the main functionality. Click to switch between variable bandwidth or center frequency. Store your favorite setting as a power-up default. Simple but very effective, this filter is continuously variable and always has near perfect characteristics unattainable with conventional analogue techniques. Kit includes: •filter module PCB (ready-built), •Bourns rotary encoder (6mm diameter shaft) , •3 x LEDs, •2 x 10 way headers, •7 resistors, 2 capacitors NOTICE: NO enclosure or instructions are provided. All construction data is online at SOTAbeams.co.uk Simple to use: the instructions are downloadable here. The instructions contain information to allow users to control the filter using a microcontroller. Example filters These plots have been made by testing a LASERBEAM-VARI using a professional audio spectrum analyzer (QuantAsylum QA400). Remember that the LASERBEAM-VARI can synthesize any bandpass filter that you want (200-3500Hz). Click on the links below to see the filters. •Typical SSB filter •Typical 200Hz CW Filter •Typical 200Hz CW filter but at 3kHz •Wide filter

SOTAbeams LASERBEAM DSP Filter Modules
SOTAbeams LASERBEAM DSP Filter Modules work much better at reducing QRM than mechanical or analog filters. SOTAbeams applies special algorithm-based software to create well-defined passbands with steep contours. SOTAbeams offers their General Purpose, CW and SSB filter modules with switchable passbands. For example, the CW module (SBM-LB-MODULE-CW) may be used with either a 550 to 850 Hz passband, or a wider 300 to 1300 Hz passband. You choose the passband based on your own band conditions. Their SSB module (SBM-LB-MODULESSB) features passbands of either 300 to 2700 Hz or 300 to 2400 Hz. SOTAbeams designers have determined that these passbands work very well for SSB voice filtering. They offer their General Purpose filter module (SBM-LB-MODULE-GP) to accommodate both CW and SSB. These modules have selectable passbands of 550 to 850 Hz and also 300 to 2700 Hz. In this way you may limit CW or SSB QRM that is outside the selected audio passband. Be advised that these modules are NOT of the plug-in style. To use them takes some knowledge and soldering skill. You will also have to add an enclosure, if desired, as well as external parts not supplied with the PCBs. As designed, these modules will drive typical "low power" earbuds all by themselves. They will also drive audio amplifiers or amplified speakers.

Order SOTAbeams LASERBEAM DSP Filter Modules from DX Engineering to hold those signals at bay!

West Mountain Radio CLRmodule ClearSpeech® DSP Noise Reduction Board
West Mountain Radio CLRmodule ClearSpeech® DSP Noise Reduction Board – a DIY project for DSP filtering. Once configured and developed, the CLRmodule can connect directly to a radio audio. It is extremely effective in making improvements to the clarity and readability of radio communications. QSO's will be more enjoyable without the fatigue of background noise. In many cases, there will be a noticeable improvement in understanding weaker signals, making contacts, and general listening. CLRmodule Digital Signal Processor (DSP) noise reduction is excellent for passing voice and CW as the DSP recognizes the intermittent nature of CW and allows it to pass noise free. It attenuates atmospheric noise, hum, hiss, whistles, and static and effectively removes heterodynes, ignition noise, lightning crashes and power line noise. The process is dynamic and changes with the interference and the signal, but the effect is rewarding. Operation is more fun without all of the background noise. Click "More Details" and the link to the manual in the Documentation tab to read and understand very important details about how to utilize this DIY project device- the West Mountain Radio CLRmodule ClearSpeech® DSP Noise Reduction Board.
