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? If so, have a look at these SOTAbeams BOXA-DUAL Amplifier Kits from DX Engineering!

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!

SOTAbeams Click2Tune Transceiver Keying Switches
SOTAbeams Click2Tune Transceiver Keying Switches are the answer for effortless ICOM low-power tuning. If you use one of many ICOM HF radios with an antenna tuner or amplifier you have noticed the lack of any convenient way to send a low-power carrier for tuning purposes. To do so requires that you to change the mode to AM or FM, reduce the power, and press the PTT. It's annoying in the shack and can be very frustrating in the field. This is all the more of a problem if you use a narrow-band antenna such as a magnetic loop that needs frequent re-tuning. It's also a problem if you use your transceiver with an amplifier. Various "solutions" have been suggested, the most common being a dongle with a capacitor and a resistor. While this works, the tune period is fixed and it will not tune reliably twice in short succession. The fixed tune period is particularly problematic if you use your radio with a high power amplifier, because if you do see a mismatch you'll want to act quickly. Click2Tune for ICOM radios provides you with complete and reliable control. It transmits a low power carrier (user selectable level) without any need to change the mode and for as long as you press the button - YOU are in control. SOTAbeams worked hard on getting the ergonomics right so that it sits nicely in your hand and they even tried three types of buttons before they found one that had the right size and "feel". They are great accessory for any ICOM radio that supports their auto-tuner. Tested on: IC-7300, IC-7100, IC-730, IC-746 (ant. 1), IC-9100 (ant. 1). For example, if your transceiver supports the ICOM AH-4, you'll be good to go! Click2Tune for ICOM is available as a kit. This kit's build time is around 30 minutes. Order DX Engineering part number SBM-CLICK2TUNEKT for the build-it-yourself kit version. In the kit you'll get: * Genuine Molex components * Mil spec 4 wire shielded cable for good RFI performance (1 meter long) * Top quality professional switch * Double-sided professional PCB and other quality parts (total 17 parts) Make it easy to tune your ICOM transceiver on LOW POWER.

SOTAbeams Antenna Center and 4:1 Transformers
SOTAbeams Antenna Center and 4:1 Transformers are a very handy feed point for a low-power lightweight portable HF doublet antenna project. Available as a kit (SBM- ACBA-101) or already built (SBM-ACBA-102). These are very versatile dipole center insulators that include these outstanding features: • Coaxial Cable Strain-Relief Built In • BNC female Connector • Water-Resistant Construction with Integral UV Resistant Cover • Antenna Wire Strain-Relief Built-in • Binding Posts for Antenna Wire Connections • Mounting Holes for Center Support Rope • Lightweight – 3.1 oz. (88g) • High Performance by Design - Flat Response from 3-30MHz • Loss: < 0.2dB @ 14MHz • Matched SWR < 1.15:1 1.8-30MHz (< 1.50:1 0.5-60MHz) • Power Rating: 125W SSB-CW; 30W Digital The SOTAbeams Antenna Center and 4:1 Transformers are useful for pre-matching higher impedance antenna systems such as doublets and folded dipoles to bring the SWR into the matching range of internal antenna tuners. In that application, the length of the feeder between the transformer and the tuner must be kept to about 6 ft. These Antenna Centers have a 4:1 matching transformer that is sometimes referred to as a balun. This isn't a choke, so strictly speaking it's not a choke balun, but it's typically referred to as a voltage balun. This transformer is designed with a lip that can be sealed using a silicone sealant if required for use in more permanent installations. We do not supply the Balun sealed as this allows users to gain access to the enclosure and allow any buildup of moisture to drain away. Note: Whenever the DX Engineering "Documentation" tab is available, please look at the associated files for additional product information.
