Wondering how well your antenna works? WSPRlite with DXplorer will tell you...


The WSPRlite is a special test transmitter that sends a signal to a Worldwide network of receiving stations. When used with our web-based DXplorer system, it's a powerful new way to evaluate antenna performance. Going way beyond antenna modelling or antenna analyzers, this unique system allows you to see how your antenna is performing in its actual location and in real-time! This type of analysis has never been possible before.


  • Uses:
  • antenna performance testing (great for contesters)
  • compare antennas
  • compare locations
  • test beam antennas
  • spot openings when you are out of the shack


...all in a way that has never been possible before!


As soon as the WSPRlite Classic was launched, people asked us for more bands. The Classic has a hardware limitation on the maximum frequency. The Flexi required significant additional development work on the hardware and firmware to add five great new bands: 17m, 15m, 12m, 10m and 6m*.


WSPR continues to increase in popularity. Because of this, the chance of co-channel interference has risen. The WSPRlite Flexi's Interference Avoidance Algorithm uses statistical data on the frequency distribution of WSPR transmitters to helps it to pick frequencies that are more likely to be clear. Other improvements in the Flexi means that it uses a much higher proportion of the available WSPR spectrum - again helping to reduce the chances of interference to and from other WSPR users.


A powerful feature of all WSPRlites is their ability to run synchronised with other WSPRlites. By analysing synchronous data the measurement performance is vastly improved compared to other comparison methods as all the data is from simultaneous transmissions. To facilitate synchronous use, Flexi users can manually enter the frequency that they wish to use for each unit. This facility is only available with the Flexi.


WSPRlite is a self-contained propagation beacon transmitter. Once configured using a special Windows or Andriod app (third party LINUX and Mac support available at WSPRlite Facebook Group), WSPRlite only needs a USB power supply to operate (no need to tie up your computer). WSPRlite operates on 630**-160-80-60-40-30-20m. The unit contains filters for 30 m and 20 m operation. Operation on other bands requires band-specific lowpass filters. We can supply a kit with filters for 160-80-40m . WSPRlite has accurate digital power control over a 16 dB range to facilitate precise measurements of antenna performance differences. WSPRlite is a low power device at only 200 mW but because of the clever encoding of the WSPR signal it has the DX capability of a 1 KW SSB transmitter (80 W CW).


WSPRlite Flexis are all soak tested in our factory to pre-age the TXCOs. They are then individually adjusted against a Rubidium standard. With these more accurate oscillators we have been able to increase the run time to 45 days. This facility is only available with the Flexi.


The WSPRlite Flexi has no internal filtering and thus the user will need to add filtering before use. We are working on a range of options and the first is our three-band lowpass filter PCB. This is sold as a bare board allowing you to implement your own filters. We offer a range of component kits for various bands. We will be introducing some more low pass filter options early next year.

Notes:
Our provision of DXplorer relies on free access to data from WSPRnet.org. DXplorer.net is provided “as is”. It is not a guaranteed service. It relies on access to third-party data over which we have no control.
*6m output power 100mW
**Check local regulations regarding unattended beacons.
Config app tested on Windows 7, 8, 10 and Vista
US customers should operate in accordance with FCC Regulation Section 97.203
