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!



40 x 50 x 10 mm
Beacon power: 200 mW (software configurable: 5 mW - 200 mW)
VSWR: better than 3:1 recommended
Maximum reverse power < 100 mW (power levels above this will damage the WSPRlite's USB chip)
Frequency range 630**-160-80-60-40-30-20m (external low-pass filter recommended below 10 MHz)
USB current: 150 mA maximum (5 Volts).
Antenna connector: SMA socket
Power connector: micro USB socket (lead supplied)


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.

    works well

    Posted by jacobus on 18th Mar 2020

    DXPLORER NOT AS GOOD AS WSPRNET. [Admin: is designed for users who want to make careful measurements. As such it is very different from WSPRnet which is designed for more general use. WSPRlite works equally well with both systems.]

    Whilst I think the product does an amazing job in testing the performance of an antenna or even propagation conditions I can't help but comment on the quality control or maybe the choice of USB port. I have had 2 USB port failures on 2 devices. Both were replaced by Richard with no hassle but it was still an inconvenience to both of us. Maybe a usb-c port would be more rugged. I did crimp down there USB port to tighten it up and have had no more failures to date. 73's de KOLIN

    Worked straight out of the box. Really useful to not occupy a computer and radio - so can be used anywhere there's 5vdc and an antenna.

    Excellent platform for rapidly and efficiently testing the perfomance and propagation charecteriatics of antennas. Very simple to use and very good value given what it does.
