Michael G0POT reviews WSPRlite with DXplorer

 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. 

  • Click here for a range of handy accessories for your WSPRlite
  • Click here for low pass filter options 


  • 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!


Powerful simultaneous antenna comparisons with DXplorer Premium

Using a simple Windows or Android interface, you program the WSPRlite with your callsign, QTH locator. Once set up, the WSPRlite does not need the computer to operate. Just connect it to a USB power supply (e.g. mobile phone charger), press the "sync" button at the start of any even minute, and off it goes! WSPRlite will make regular transmissions that are automatically received by stations around the world. These stations send their reports to a central website where you can see where your signals are reaching within seconds. Even more fun is to leave your beacon running and monitors its performance using DXplorer on your smartphone or tablet. This is a great way to see how your station is doing when you are at work - or even on holiday!* Take a WSPRlite on your next business trip or cruise and see where it it being heard while you sit at the bar.

What makes our product unique is the ability to compare antennas and location. We use the WSPR data to generate a special metric, DX10. We recalculate your DX10 range (km) every 2 minutes. DX10 is a great system performance indicator! The best HF system will give the longest DX10 ranges. Because you can compare the DX10 ranges for two station in real-time, you can see which one is the best - and by how much. Along with real-time DX10 graphs we calculate a mean and maximum DX10 score for each station - very handy if you make changes to your antennas to see what the changes actually do!

For beam users we generate on-the-fly Great Circle maps that have colour-coded spot locations showing signal to noise ratios. If you are doing a comparison, you can easily see who got the furthest spots and who was strongest!


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).


The DXplorer website is designed to operate with WSPRlite. DXplorer provides you with antenna performance information and propagation information in a new easy-to-use format. DXplorer has been optimised for use on mobile devices. Use of is free for any WSPR user but WSPRlite users access Premium facilities including detailed antenna comparisons.

    Excellent WSPR Transmitter

    Posted by Samir ( HZ1SK ) on 22nd Apr 2018

    This is an Excellent piece of equipment, it can&#039;t be really easier to set it up and be on the air in a very short time. I was really amazed what a 200 mW on WSPR can do.. My location is in Jeddah - Saudi Arabia and I am the first WSPR station in the Arab world. Well done SOTABEAMS. I only wish if something can be done to extend the 30 days limit.

    Excellent piece of device

    Posted by SM4ETE Christer on 21st Apr 2018

    Easy to set up both from PC and Android. Amazing distances covered even with 10 mW!

    Very very nice ..

    Posted by Frans Boot PA0FBR on 16th Mar 2018

    This piece of equipment is the ultimate antenna tester and bandopening spotter. Beside this is it extremely good to help understand that QRPP is working. What about from PA to the states or nothern part of Norway with only 5 mW of power on 20 meters. Its keeps amazing me every day. Very nice gadget to have hi.

    It’s amazing what 200mw can do if you get the noise bandwidth down. The WSPRlite is easy to configure and use and the DXplorer web site is a useful compliment to WSPRnet for displaying your results. Highly recommend.

    Easy setup

    Easy setup. Works as advertised. Great way to check propagation from different locations, different bands, and different antennas.

    Love this device!

    Posted by Lew on 23rd Nov 2017

    It just amazes me that I can collect data on my various antennas capabilities. Such a reasonable price for a device that offers me the kind of information that will allow me to fine tune my antenna system and return to me an instant result. Thank you Sotabeams.

    Can&#039;t over praise this little gem

    Posted by Gur on 22nd Nov 2017

    Heard a lot about the WSPlite and finally got the proper setup to buy and utilize it.

    You actually buy a system not a product, and every part of it is ingenuous. For the first time you have a real feeling of your antenna setup real performance - and in an automatic way.
    Setup takes few minutes and you are up transmitting and automatically collecting statistics from all over the world. AMAZING !

    A remarkable piece of gear!

    Posted by Unknown on 9th Nov 2017

    We used this on an antenna comparison test of 3 antennas: Lazy H, Dipole and Vertical on 20 meters over the weekend. Fascinating to see the coverage for each... especially with a mere 200mW.

    Well done!
