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.

...all in a way that has never been possible before!
WSPRlite Flexi and Classic compared at a glance:
Note: 60m now supported.
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.

Great product, easy to set up and results are impressive . It would be great if filtering has been included, and the ability for the software to switch bands in a schedule, but here’s for future models.
Works fine. Easy to setup. Make or get low-pass filter for band desired and get on the air. I was surprised to see that 200 mW was enough on 160 meters to reach Antarctica, over 15000 km. Just amazing. Will make more testing on other bands too. Have made LPF for 80 and 160 already. And have BPF available for 20 and 15. Planning to put more permanent installation on 30 m with some short vertical. 73 de Jukka OH4MFA, OG4T
Great development on original. I plan to check aerials and propagation particularly, on 10 and 6, during the coming sporadic E months. With these products, you quickly find out if an aerial working without misleading 59/599 reports. Especially useful for height or space limited aerials.
Many thanks from Far North for Flexi! Installed in KP69AK near VHF Beacon. Full info here! https://ua1zfgsite.wordpress.com 73 Richard & All from UA1ZFG, Vadim
I already own three WSPRLite Classic models which provide flexibility to perform real time tests against different antennas under different call signs. The new WSPRLite Flexi adds some great new features - more bands & a more stable crystal oscillator which allows for a longer continuous running period. As ever, amazing results on WSPR using mW rather than Watts or KW! Very pleased, and very addicted! 73, David M0VGA
Très bon produit ; je passe beaucoup de temps a tester mes antennes Happy new year
