Test Equipment & Analyzers Filter Boards and Band Kits SOTAbeams Filter Boards and Band Kits are used for the WSPRlite Classic, WSPRlite Flexi, or for your SDR front-end filter projects. 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 three-band board features a manual band change jumper header and comes with an SMA male cable to connect to the WSPRlite and a board mount SMA female connector for your antenna feedline. Filters also work with QRP radios other than the WSPRlite Classic or Flexi.

In these places, the HT can suf er from front end overload and signal blocking. This bidirectional bandpass filter can prevent that out-of-band signal overload. SBM-BPFT-100 2M Bandpass Filter ............................................................... $57.99 SBM-PCB3BLPF Enclosure Kits for SOTABeams Low Pass Filter Kits Sturdy and easy to assemble, DX Engineering’s enclosure kits are custom made to securely house SOTABeams Low Pass Filter Kits. It only takes a few simple steps to mount the filter and build the box. Everything you need is included: top and bottom pieces for the aluminum case, PCB spacers, hardware and stick-on rubber feet. The enclosures have a sof grommet to protect the SMA cable and two easily removable hole covers to allow bandswitching of the optional filter assembly. The new V 1.2 enclosure (DXE-LPFV1-2-CASE) has been designed to house the SBM-LOWPASSKIT, SBM-LOWPASSKITHB and SBM-PCB3BLPF. DXE-LPFV1-2-CASE Enclosure Kit for SOTABeams Filter Kits, V 1.2 ................$55.99 WSPRlite Flexi Propagation and Antenna Tester Building on the success of the classic WSPRlite, the WSPRlite Flexi is a special, low-power test transmitter that sends a signal on your antenna out to a worldwide network of receiving stations listening in the WSPR mode. When used with the web-based DXplorer system, it's a powerful new way for contesters and DXers to evaluate antenna performance. This unique system of propagated signal analysis goes beyond antenna modeling or antenna analyzers and allows you to see how your antenna is performing in its actual location and in real-time! WSPRlite Flexis are all soak tested to pre-age the TXCOs. They are then individually adjusted against a Rubidium standard. With this more accurate oscillator, SOTABeams has been able to increase the run time to 45 days. Additionally, the WSPRlite Flexi's Interference Avoidance Algorithm uses statistical data on the frequency distribution of WSPR transmitters to help it pick frequencies that are more likely to be clear. The handy device enables you to perform antenna performance testing; compare any antennas (base, portable and mobile); compare locations and antennas—yours, your friends, even compare your antennas and location with the big guns; test beam antennas against dipoles versus verticals; and spot openings when you are out of the shack. The WSPRlite Flexi is capable of operating 630, 160, 80, 40, 30, 20, 17, 15, 12, 10 and 6 meters (5 more bands than the WSPRlite), but requires external low pass filtering through use of the 160/80/40M SBM-LOWPASSKIT.

The new display can show graphical and numerical SWR, total impedance (with X and R values), frequency and battery life. SWR and impedance are displayed simultaneously, allowing you to easily determine resonant frequency. The analyzer will scan a frequency range in mere seconds, to make antenna adjustments and troubleshooting much quicker. The analyzer has broad frequency coverage, twin analog meters and two antenna connection jacks. It is powered by six AA batteries, which provide up to 14 hours of operation.
