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.

    Oustanding Product and great customer service

    Posted by Peter on 27th Oct 2017

    I have been using this for more than a year and it is a wonderful product. I am also very happy with the great customer service I received and Richard was able to answer all my questions

    What a fantastic bit of kit for anyone interested in antennas or propagation. Seriously interesting results from my simple end-fed antenna. Highly recommended.

    Third review after many weeks of testing

    Posted by Andy G3VMZ on 24th Oct 2017

    Initial results at 200mW on 20m were not encouraging, changes to height and direction of the spiderbeam were made and results have improved.
    Given the variable conditions over August and September I was pleased to have spots as Far East as Moscow, south to Greece and Canaries, North to Tromso. Unexpectedly came Canada&#039; eastern provinces and south to Georgia USA - all repeated over many days and a couple of weeks ago just when I thought I had fathomed the spider beam radiation pattern came a ZS5 in South Africa and two days ago a VK2 in NSW! All on 200mW.
    Great product.

    I am satisfied with the tracking tool, good service.

    Posted by Andrey Markelov on 28th Sep 2017

    It&#039;s a good idea to create this device, useful and interesting technically modern!
    Easy to use and configure.
    Good software.

    Great Product

    Posted by Andy Hearn G3UEQ on 21st Sep 2017

    I like to experiment with different antennas and this seemed the ideal way to check out radiation patterns etc. So far has exceeded all expectations and gives me clear indication, conditions permitting of my antennas performance and directivity. Got a spot in Perth within 3 days of use on 40m with just a 60 foot inverted L! Make sure instructions are read before using.
    Wonder how I managed before !

    Namibia V51 land

    Posted by Derek on 19th Sep 2017

    We have now setup three WSPRLite transmitters in Namibia
    V51DM V51RS V51WF .The setup was simple and worked first time we are testing various antennas with these transmitter and are getting good results we do the comparisons after a 24 hour period.

    Thanks Richard for the prompt delivery of transmitters

    Great product well made 73 Derek V51DM

    Testing different antennas

    Posted by Hakan on 15th Sep 2017

    The WSPRLite is very easy to use.
    I can run it for nearly 3 days from a 10000mA powerbank.
    Perfect now with the new Android app for field use.
    I use a Tablet in the field to do the setup.
    I wish it had all HF bands to use.

    Learn a lot about propagation

    Posted by Mike VK2AMF on 2nd Sep 2017

    Item was well packed and very fast service.
    No problems experienced with setting up.
    Results are fascinating, so far only used on 40m but amazing how such low power traverses the globe. Would be interesting if one could have some graphical representation of the duration of reception of ones signals.
    Not sure how well protected it is from static and RF fields so have just left it running when I am not transmitting (on another antenna) and no storms forecast.

    WSPR Lite

    Posted by Brano OM6RU on 1st Sep 2017

    I have used my WSPR Lite for the last 2 days on my 30m dipole. I&#039;ve had almost 10,000 hits on my 30m dipole inc one from VE. I used 200 mW.

    Works As Advertised

    Posted by John Hilliard on 31st Aug 2017

    Received the product and sure enough it works great. Interesting to see how far 200mw can get you!
