Choose the Low Pass Filter Board and Band Kit components for the specific bands on which you want to use your WSPRlite. Build these high performance seven-element Chebyshev low pass filters to eliminate harmonics and spurs. They function bi-directionally and may be used for QRP transceivers or for receive. Each board features a manual band change jumper header and comes with a SMA male cable to connect to the WSPR lite and a board mount SMA female connector for your antenna feedline adapter or adapter cable. SOTAbeams Filter Boards and Band Kits are available in four versions. These three have a revised board layout: - SBM-LOWPASSKIT Low Pass Filter Kit for 160, 80 and 40 meters, version 1.2 Board - SBM-LOWPASSKITHB Low Pass Kit for 20, 15 and 10 meters, version 1.2 Board These two include the filter components, connector and one cable. - SBM-PCB3BLPF Low Pass Printed Circuit Board only, version 1.2 Board. This kit includes only the board, SMA connector and one cable. Add to your cart the specific component Band Kits for the bands you want to use. All 11 bands are available from 160-6 meters. After you finish building one of these three boards, it fits into the updated accessory enclosure model DXE-LPFV1-2-CASE. NOTE: These three version 1.2 Boards DO NOT fit into the DXE-SB-LPF-CASE -------------------------------------------------------------------------------------------------------------- - SBM-LPFKITDXEPCB Low Pass Filter Kit for 160, 80 and 40 meters, version 1.1 Board. This kit includes band filter components, connector and one cable with the old PCB. When this v1.1 kit completed, it is the only board that fits into the original DXE-SB-LPF-CASE. (NOTE: This v1.1 board does not fit into the updated DXE-LPFV1-2-CASE which fits only v1.2 boards). --------------------------------------------------------------------------------------------------------------- Buy and build more than one SOTAbeams Filter Boards and Band Component Kits to use your WSPRlite Classic or WSPRlite Flexi on more than three bands. Don't forget to add the adapters shown in suggested parts. These low pass filters also work on QRP transmitters and all receivers.

SOTAbeams Pico Trap Kits
SOTAbeams Pico Trap Kits are a pair of miniature antenna traps that you can build to create a super lightweight portable multiband HF wire antenna. Designed for QRP portable operations at 10 watts or less, Pico Traps allow the hobbyist to make their own two or three band dipole or end-fed halfwave. Pico Traps are: - The smallest, lightest traps on the market - Easy to adjust in series or parallel modes - Super for multi-band stealth antennas - Streamlined shape to reduce snagging on vegetation - Attachment points for antenna wire. Work great with Stealth Wire - Easily waterproofed with Liquid Electrical Tape for extended use - Can be mounted inside of 1 inch PVC conduit - Weigh less than 0.2 oz. Perfect for use with IC-705, FT-817, FT-818, KX3, KX1, HB1B and other similar radios. Instructions are linked in the Documents tab on the "More Detail" page. What do you get with a Pico Trap kit? 2 x High quality Pico Trap PCBs 2 x T50-6 toroids 2 x nylon mounting kits for toroids 2 x SMD 100pF AVX RF Capacitors, 0805 High Q, Ultra-Low ESR 22 AWG (0.6mm) wire for toroids Pico Trap Kit Specifications: Size: 1.4 x 0.6 in.

SOTAbeams WSPRlite Power Conditioner Kits
SOTAbeams WSPRlite Power Conditioner Kits are ideal for running your WSPRlite Antenna Performance Analysis System from a battery or "wall-wart" power supply. WSPRlite Power Conditioners convert any 7 - 20 Volt DC supply into a super-clean and quiet 5 Volt USB supply - perfect for your WSPRlite! SOTAbeams use a linear regulator to avoid the noise problems so often associated with cheap switching regulators. Rated at 200 mA and with a re-settable breaker, these power conditioners will keep your WSPRlite happy - and safe too. Their DC input is protected against voltage spikes by a special TVS diode and is provided with additional smoothing with a low-ESR input capacitor. These features have been added in case you wish to use your WSPRlite in a mobile setting. Unlike simple chargers, SOTAbeams also condition the data lines to avoid unwanted noise affecting your WSPRlite. WSPRlite Power Conditioner Kits are supplied with a PowerPole for the DC input and a standard USB output. It's ideal for running your WSPRlite at home or in the field! The PCB has M3 mounting holes (mounting hardware is not supplied with board kit). These kits require assembly, including soldering to a PC board. However, they are suitable for beginners. Supply clean, stable power to your WSPRlite! Order SOTAbeams WSPRlite Power Conditioner Kits from DX Engineering!
