SOTAbeams Filter Boards and Band Component Kits
SOTAbeams Filter Boards and Band Kits are used for the WSPRlite Classic, WSPRlite Flexi, or for your own QRP transmitter, SDR front-end filter projects or on any receiver. 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.

DX Engineering Electronic Protection Components
DX Engineering Electronic Protection Components may be used in a variety of electronics and radio applications. These are wire lead components that can be used on circuit boards or in multi-purpose connection devices. Choose from the components listed for detailed specifications: DXE-MOV-82VDC-10 Metal Oxide Varistor, Surge Protector, max. 82VDC/50VAC Pack of 10 DXE-GDT-4KV-5 Gas Discharge Tube, Surge Arrestor, 4kV, Pack of 5 DXE-TVS-1500-10 ESD Suppressor, TVS Diode, Bidirectional, 17VDC max., Pack of 10 DXE-CAP-PT1UF-10 Capacitor, Ceramic, 0.1uf, 1kV DC, RF Bypass, Pack of 10 ---------------------------------------------------------------------------------------------------------------------------------- This series of protection components are well suited for the DXE-CLTB Control Line Terminal Board that provides a flexible and simplified approach to control line surge protection. The DXE-CLTB is a small, 3 inch square printed circuit board (PCB) with four ten-wire compression screw terminal blocks that handle from 14 to 26 AWG conductors and up to 10A. The two outer terminal blocks are for input and output of the control wires and the two 45 degree angled ten-wire compression screw terminal blocks are for connecting electronic surge protection components. This provides for the choice of components to install between the control line and ground to provide shunt protection. Metal Oxide Varistor (MOV), Gas Discharge Tube (GDT), EMP Suppressor TVS Diodes, RF Bypass Capacitors and other wire lead components are easily connected between the control lines and ground. For effective protection wherever shunt devices are used, a low impedance ground is critical. The DXE-CLTB Control Line Terminal Board has four corner grounding screw holes for mounting on metal standoffs to a metal grounding panel inside an enclosure. DXE-CLTB-M Control Line Terminal Board includes a 10-pack of MOVs.

Homebrew Cookbook
If you're interested in home construction, Eamon Skelton, EI9GQ is the acknowledged expert in this field. The RadCom columnist on the subject, Eamon brings his enthusiasm, common sense and easy-to-understand approach to the "Homebrew Cookbook," such that readers will be reaching for their soldering iron with inspiration. This 208-page paperback starts with the very basics of homebrew and progresses to advanced topics. There are construction methods that take you right through all the main techniques, from dead-bug layouts to dedicated printed circuit designs. The PCB section is packed with simple ideas that will allow you to make PCBs cheaply without any specialist equipment. Eamon even shows you how to use sunshine or cheap halogen security lights as a UV source! Construction projects start with receiver designs and a simple direct conversion receiver, followed by a more sophisticated superhet receiver. "Homebrew Cookbook" also includes an SSB transmitter, PA and a VHF transverter. All the designs are modular, making it very easy to extract sections for other uses and adapt the designs to suit your needs. Where test equipment is required, Eamon has simple circuits on hand to enable you to build your own rather than have to buy commercial equipment. Eamon also deals with homebrew antennas, offering lots of useful tips for making practical and effective antennas with junk-box components. Throughout the book is an adherence to homebrew principles, as all projects use simple construction techniques with cheap, readily obtainable, components. Eamon even tells you how to make the most of eBay to find what you need.

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!
