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!

The WSPRlite kit contains:

- WSPRlite kit with preassembled PCB
- cableset USB 2.0 micro - 0,5 meters

Powerful simultaneous antenna comparisons with DXplorer Premium

Using a simple computer 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!

Hardware

WSPRlite is a self-contained propagation beacon transmitter. Once configured using a special Windows 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 630-160-80-40-30-20m. 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).

Software

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. Each WSPRlite comes with a free 1 year subscription to DXplorer Premium worth £19.95 - allowing access to additional facilities including detailed antenna comparisons.

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 you will need to add filtering before use. There are several filter options here at the FUNKBOX shop. One is the two band filter kit which is sold as a bare board allowing you to implement your own filters.

Low pass filters for 40m, 80m and 160m (all three supplied). The lowpass filter kit builds up to a neat pcb (73 x 97 mm)  with low pass filters for 7 MHz, 3.7 MHz and 1.8 MHz. The filters are selectable with movable jumpers. The kit is supplied with a prewired coax tail with SMA plug to connect directly to your WSPRlite and a board-mounted SMA socket for connecting your antenna: no fiddly connectors to install!

The PCB has been designed with new builders in mind. High quality through-hole components have been used throughout including Grade 1 Murata/TDK C0G/NP0 capacitors, Grade 1 solderable enamelled copper wire and gold plated jumpers.

Each filter is a 7 element low-pass with great performance and low loss. The kit is rated at 25 Watts - suitable for general QRP transmitter use. Board has M3 mounting holes for easy use.

Easy to make, easy to use!
