SOTAbeams Carbon-6 Compact Ultra-Light Telescopic Masts
SOTAbeams Carbon-6 Compact Ultra-Light Telescopic Masts extend to 19 ft. and collapse to a handy 17 inches! Their super-lightweight carbon-fiber composition and nested length is perfect for carrying in your backpack. They're light enough to take on any excursion and are easily telescoping for rapid deployment. Ultra-lightweight portable operators, like mountain-topping backpackers, need a special mast to support their antennas. The new Carbon-6 has been designed for exactly this role. The Carbon-6 has been manufactured specifically for SOTABEAMS. Carbon fiber masts are slightly conductive and so extra care must be taken when using them near power lines. These masts are suitable for supporting lightweight horizontal or inverted-vee antennas. Because of their flexibility, we recommend a maximum antenna height of 16 ft. (5 meters). We do not recommend using these masts for supporting the center of dipoles with heavy feedlines or for use to support a vertical antenna. They are perfect for supporting the center of lightweight end-fed wire antennas. This mast is destined to become a popular choice for the portable operator who just wants to travel light and undertake more "extreme" forms of travel. Each section is set by friction lock, pulling each section firmly with a twisting motion for best lock. When erecting always start with the smallest section. When taking down always start with the largest section. Mast sections may be removed by unscrewing the end cap at the bottom of the mast and removing unwanted sections. Detailed Specifications of the SOTA beams Carbon-6 Compact Ultra-Light Telescopic Mast: - Extended length: 19.6 ft. max. (6 meters), approximate - Packed length: 17 in. (43 cm) - Number of sections: 18 - Wall thickness: 0.04 in. (1 mm) bottom - Weight: 10.6 oz. (300 g) - Mast Material: carbon fiber - Tube Diameter: Base 1.2 in. (31 mm), Top 3/32 in.

SOTAbeams Fuser 6 DC Distribution Boxes
SOTAbeams Fuser 6 DC Distribution Boxes are the lightest PowerPole® distribution boxes… by far! SOTABEAMS PowerPole® Fuser-6 boxes make light work of connecting five accessories to your power source (they have one input and 5 outputs). All of the connectors are individually fused. In a typical shack you might have a 100 Watt HF radio, a 50 watt 2m FM radio, an antenna tuner and a QRP rig all connected to your Fuser-6 - and still have a spare connector! Fuser-6 boxes are supplied with three 25 Amp and three 5 Amp fuses. Standard automotive blade fuses make replacement easy - these are widely available with values from 1 to 30 Amps. Fuser-6 units incorporate a polarity warning system; lights GREEN for CORRECT and RED for REVERSE. It's handy when you have a battery connected to the system to help avoid damage to your equipment if you accidentally get the battery connections reversed. Fuser-6 internal circuitry is rated at 25 Amps (30 Amp surge); no mean feat for a PCB design. To achieve SOTAbeams had to use a special PCB with double weight copper. They also use a clever design to further improve the current handling: ultra-wide copper tracks are used on both sides of the board. The boards are then roller tinned (on both sides) to reduce the resistance and handle heat even better. They use plated through holes, carefully located to ensure an even current distribution between each face of the board. Of course, Fuser-6 boards use genuine Anderson PCB contacts for lower contact resistance and improved reliability. NOTE: For best kit results use a soldering iron of at least 50 Watts. Additional flux is also helpful to ensure a good result. Additional details: * 25 Amps continuous, 30 Amps surge (adjacent connectors) * 1 input, 5 outputs * Power Bus resistance typically less than 1.80 milliohms end to end * Weight 135 g (less than 5 oz.) * W 68 x L 130 x H 40 mm (excluding connectors) 2.75 x 5 x 1.6 in. Whether you use one for your go kit, QRP setup or for use in the shack, these SOTAbeams Fuser 6 DC Distribution Boxes from DX Engineering are a handy DC power solution.

SOTAbeams Speech Compressors
SOTAbeams Speech Compressors are available in two versions; ready-built or as an easy-to build kit with a build time of approximately 40 minutes. Unleash your DX potential! The FT-817 and FT-818 are great little radios, but their SSB speech power does lack punch. Here is a fantastic external AF dynamic compressor that will aid readability and maximize the performance of your radio, which is essential when using QRP. Speech Compressors work by raising the average level of your audio signal, giving greater "talk power" with an apparent improvement of up to 6 dB! SOTAbeams Speech Compressors are Plug- and-Play! They have a modular 8-pin jack for your Yaesu microphone and a modular cable is included to connect the unit to the radio microphone input. The compressor function can be switched on or off, and the module draws its DC power directly from the transceiver (approximately 10mA). The compression level is adjustable and modifications to your microphone or transceiver are not required! An additional, very useful feature of this compressor unit is a tuning tone. Press the Down button on the microphone while the PTT is depressed to activate the tone, which is useful for adjusting tuners and antennas. The SOTAbeams Speech Compressors are also suitable for use with all versions of Yaesu FT-900, FT-857, FT-897 and FT-450 transceivers. IMPORTANT: Speech compression cannot be used on FM mode.

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!
