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 ContestConsole Switching Unit for ICOM

SOTAbeams ContestConsole is a control switch unit for Icom transceivers, provides full access to compatible ICOM rig contest memory functions, and more. Easily connected between your radio and microphone, it is simple to use and feature packed. SOTAbeams ContestConsole features (dependent on Icom transceiver model): * Instant access to voice, CW and PSK memories (they do not need to be displayed on the transceiver screen) * TX PTT button * TX low power tune function – sends a 10W carrier (optional Tune Lead interface cable required) * Pushbutton frequency control (up and down) * External PTT socket for footswitch * Auxiliary microphone socket (3.5 mm) * Specifically designed to work with the IC-7300 but supports a wide range of other Icom transceivers--see "More Details" tab In general, if the radio is compatible with one of ICOM's standard 8-pin microphones (such as HM-36, SM-50, HM-219), then the ContestConsole PTT, frequency up, frequency down buttons, and the 3.5mm microphone socket should work for an electret element. If the radio manual mentions "external keypad" in relation to voice/CW/RTTY memories, then the ContestConsole memory buttons should work. Transceivers that are compatible with the AH-4 tuner should work with the ContestConsole tune button (optional Tune Lead interface cable required). An adapter cable (OPC-589) is required if the radio has a modular microphone connector instead of an 8-pin circular microphone connector. Operational Tips: 1. Some transceiver settings may need to be changed for the memory buttons to work. Search for "external keypad" in your transceiver manual for details. 2. Never connect two microphones at the same time to the ContestConsole. When connecting a microphone use either the 3.5 mm socket or the 8-pin socket, not both. 3. On some Icom transceivers, an external storage memory card or USB drive may be required for voice memory functionality.

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 HF Antenna Trap Kits

SOTABEAM HF Antenna Trap Kits are a clever design with flexible mounting arrangements to make them easy to build and use. They are available in two power levels, 100 watt traps are listed here as SBM-HFAT-101 and 20 watt traps are SBM-HFAT-102. Each kit includes parts to build two (2) traps. Make your portable single band antenna into a multi-bander with our lightweight antenna traps. You decide on the frequency when you build them; recommended range 7 - 25 MHz. Alignment of each trap is accomplished easily with an antenna analyzer. For QRP super lightweight traps, see SOTAbeams PICO TRAPS for 10 Watts (DX Engineering part SBM-PITK-100). Included in each SOTABEAMS HF Antenna Trap kit: -2 x high quality trap PCBs with plated through holes -4 x 100pF 1kv capacitors (used in series or parallel to give 50pF, 100pF and 200pF options) -2 x mounting hardware for toroids -2 x toroids (T94-6 for 100W and a lighter T68-6 toroid for 20W) -Enameled copper wire to suit the power level Traps can be used in one of two ways. These SOTAbeams traps can be used either way, it's your choice: 1) By using a trap resonant on the higher frequency that you want your antenna to work on, traps work as an effective isolator. In this application, the trap needs to be resonated in the band. This configuration makes the antenna easy to adjust as the sections do not interact much. In this configuration, our traps show a loss of typically < 0.7 dB. 2) By using a trap resonant between the two bands that you want to use (typically 1 to 2 % percent below the band edge of the higher band), losses are reduced but adjusting the antenna is much more difficult as the two sections interact. In this configuration our traps show a loss of typically < 0.3dB. We recommend that you resonate your traps at the lowest edge of the band that the trap is to work at. So for a 20m-40m dipole, resonant your trap at 14.0 MHz. This tends to be a reasonable compromise between trap loss and ease of antenna adjustment. Instructions are linked in the Documents tab on the "More Detail" page. SOTAbeams HF Antenna Trap Kits Specifications: PCB Dimensions: 2.599 x 1.181 in. (66 x 30 mm) Insertion Loss: 0.3 – 0.75 dB depending upon resonant frequency Impedance at resonance: 20,000 Ohms, typical Weights: 20 W traps 0.4 oz. (10.6 g), 100 W traps 0.6 oz. (16 g)

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!

SOTAbeams BOXA-DUAL Amplifier Kits

SOTAbeams BOXA-DUAL Amplifier Kits are ideal for incorporating into your own designs. However, for additional flexibility these amplifier and enclosure kits have been designed to allow your LASERBEAM-DUAL filter module (not included) to be used with all your favorite radios. They have a professional look that will compliment your shack. BOXA-DUAL enclosures have laser-cut gold panels which screw into a rugged extruded aluminum case. BOXA-DUAL kits consist of a PCB that the filter module (not included) plugs into; together with an audio amplifier. The front panel features the CW Tuning LED (Sig) and Overload LED (Lvl) as well as a bandwidth switch (W/N) and volume control (Vol). The rear panel has 3.5 mm stereo jacks for audio in and out as well as a power jack for a DC supply (5-15 Volts). Power input is via a standard 2.1 mm power plug (supplied). The board will drive headphones or a small speaker. By changing two resistors, audio output can be increased up to 1.5 Watts which will drive a larger speaker. Because the filter module is a plug-in unit you can swap between different LASERBEAM-DUAL modules depending on your application. These kits use all through-hole components and are an easy build for a beginner. Build time is about 30 minutes. IMPORTANT NOTES: These kits: * Include amplifier and enclosure * Do not include a LASERBEAM-DUAL filter module * Are not suitable for LASERBEAM-VARI or LASERBEAM-817 filter modules Are you thinking about a LASERBEAM-DUAL filter module?

SOTAbeams Click2Tune Easy Tuning Dongle for Yaesu FT-817, FT-818, FT-857 and FT-897

SOTAbeams Click2Tune Easy Tuning Dongle for Yaesu FT-817, FT-818, FT-857 and FT-897 makes keying the radio and using a tuner a snap! If you use one of these Yaesu transceivers with an antenna tuner, you've noticed the lack of simple way to quickly send a carrier for tuning. To do so requires a change of mode. Given the slightly clunky user interface on these radios, sending a tone at the desired power level can require several key presses. It's annoying in the shack and can be very frustrating in the field. This is especially troubling if you are using a narrow-banded magnetic loop that needs frequent retuning as you traverse the band. The Click2Tune Easy Tuning Dongle makes the tuning process so much easier! This tiny dongle contains a sophisticated microprocessor that plugs into the back of your radio. Once set up, tuning just requires a double click of the microphone PTT switch to send a carrier; that's all. Brilliant! With the FT-857 and FT-897 you can tune at low power, as the Click2Tune allows you to select the tuning mode. You are able to tune at 25 watts--especially important for protecting auto-tuners. By the way, it is the same Click2Tune Dongle that can be used on all of these radios; you don't need different types. The SOTAbeams Click2Tune Easy Tuning Dongle for Yaesu FT-817, FT-818, FT-857 and FT-897 is a very useful accessory that is sure to make your mobile and portable operating easier!
