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!
WSPRlite Flexi and Classic compared at a glance:
More bands...
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*.
Interference Avoidance Algorithm
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.
User defined transmit frequency
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.
Increased Maximum Run-time**
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.
Low Pass Filters
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.

WSPRlite Flexi
Great product and works great in practice.

WSPRLite Antenna Analyzer
Unit is very frequency accurate could be used as a freq generator if app was available. Some drift on 6M in the decode at 200mW but I know how hard this is to achieve. Would be nice to have the original 80M frequency band since this is still used. In general very pleased with their achievement with the frequency and timing accuracy

WSPRLITE Flexi
Simple to set up and very useful for checking antenna performance; basically, does what it says on the tin.
-
Amazing gadget; the power of very low power!
I was delighted since the very first moment that I set it up to work. It is very easy to set-up, run, gather data and display QSOs from all around the world. A very didactic way too to test the effectiveness of your antenna or to compare data.

Very effective and useful tool
Recently upgraded from the WSPRlite classic and it does everything as expected on more bands. Works fine through the low pass filter kit also available through Sotabeams, and have had a couple of reports from Australia (WSPRlite in UK) using 100 mW -impressive!

Wsprlite has potential!
Have been using Wsprlite for a few months now. Am impressed with 200mW. Great tool for refining antennas.
Unable to get drivers to work with Windows 10, had to resort to old XP device which won't work online. This means I cannot access premium mode.
Would like to register, even if I have to pay for access to premium.
Any suggestions?

Brilliant little gadget!
Having recently come back to amateur radio in retirement, I cannot believe the technology now available for little effort and cost. To see signal report 'spots' appearing on my 40m DXplorer map from Australia, New Zealand and the USA on the first evening of use, was simply amazing. An outstanding method of antenna analysis and all using 200mW from a box the size of a matchbox!! Many thanks!

Funziona alla grande.
Ottimo prodotto. Funziona molto bene ed il suo utilizzo è semplice ed efficace. La configurazione tramite PC non ha dato nessun problema. Ho acquistato la versione Flexi e sono molto soddisfatto. 73 de IU4HMZ

A very good performer
I have completed LPF kit for 7 and 14 Mhz and tested the antenna analyzer (WSPR Flex) on those bands. I works as expected in conjuction whith my long wire antenna (22 m long) and ATU. My OTH is Sweden and my longest connections was North America and Austalia (Tasmania) on 14 MHz. I'm really astonished consider the output of 200 mW power. I really recommend this item for antenna analyzer work!
