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. Note: Whenever the DX Engineering "Documentation" tab is available, please look at the associated files for additional product information. Are you tired of battling the QRM? Order SOTAbeams LASERBEAM DSP Filter Modules from DX Engineering to hold those signals at bay!

Phonema Oscar Speakers
Phonema Oscar Speakers deliver "Sound from the Sky" with an innovative overhead spherical design that envelopes the listener in a unique and engaging audio experience. Oscar is designed to be hung above the radio desk. The directivity of the speaker allows the audio to be concentrated in a 57 degree beam, limiting the travel of radio sounds beyond the radio room and reducing the nuisance to the rest of the home. With this speaker suspended from the ceiling, centered above the radio operator, the sound is perceived as coming from within, similar to wearing headphones, resulting in improved mental concentration on signals and reduced fatigue. Carefully designed with top grade materials, Oscar Speakers reproduce clear and comfortable sound. From weak Morse signals to strong broadcast and all modes in between, Oscar Speakers are an excellent choice, especially for places where there is no room for a good speaker to be placed on the desk or shelf. The Phonema Oscar-1 audio is connected by cable. Exquisite attention to design details provides a speaker with warmth and a touch of elegance and personality for your shack. Order Oscar-1 and all Phonema Speakers from DX Engineering, your exclusive North America Phonema dealer.
