SOTABeams WSPRlite overview

- An overview of the WSPRlite beacon from SOTABeams.
My thanks to Richard G3CWI for providing the test unit.
You can see some of my experimental results using the WSPRlite on my website at www.peanutpower.co.uk/efhw where I compare my two favourite SOTA aerials; the dipole and the EFHW.
*Notes*
- If you try starting dead on the start of the minute it's possible to be too quick. Aiming to press the start button at 1 or 2 seconds past the start of an even minute may help. If you don't see hits after one or two transmissions then try restarting and check the accuracy of your clock!
- I misspelled Joe's name in the video...apologies Joe for making you a Jo...it doesn't diminish your amazing work :o)
You can order the WSPRlite from www.sotabeams.co.uk

You have made a new convert. Thank you for the excellent presentation. Thankfully it is not a kit since I am too old and shaken to attempt building something. I appreciate what you have done for us. N4KBM
I was glad to finally found Michael who speaks Oxford style. Enjoyed the explanation although I am an old foy amog those who have been using WSPR. 73 de HA6NN
Brilliant! A video that didn't send me to sleep in the first 30 seconds! One thing, though: have seen occasionaldecodes at -30dB S/N.
I have seen comments on the forums of improvements that enable decodes at even lower SNR. I haven't investigated yet to understand if there is a change to encode/decode algorithm or if the duration of transmission is longer...that's my homework!
What make is the loop ?
digitalmediafan The Loop in the video is an Alex Loop (see www.alexloop.com) but see also my video on the W4OP loop which was very good.
Thanks very much but both loops too expensive for me unfortunately
Where did you get your particular battery from ?
digitalmediafan The battery pack I use at 9:38 was a simple ‘phone booster’ type pack...this particular one was a freebie from Blackberry and doesn’t go into sleep mode due to the low and intermittent current draw of the WSPRlite. I think these are quite cheap to buy but if your battery pack does keep going into standby, SOTABeams do a little power manager that you plug in which keeps it awake.
well done video. I thanks for takingthe time and for doing such an informative video.
Great, well put together video.
Always a pleasure...hope you find my videos informative and interesting. If only i could squeeze all that into a shorter duration!
Well done video!
thanks looks like sotabeams going to take more of my cash!!
well explained vid 73
Does it only transmit one band at a time? What would be cool is if it could be configured to transmit on certain bands during various times.
Yes, as of March 2017 it is only designed to transmit on a single band without first reconfiguring it with the application. Updating the firmware to enable the option for it to band-hop over time would be a sweet mod. Ping that idea to Richard at SOTABeams.co.uk or raise it on the Facebook group (WSPRlite for DXplorer). I think it would have lots of supporters.
Thanks Michael, great video and good information.
I've not got this connected to my shack PC yet. Does anyone know if the frequencies this device uses are the same frequencies as those used by WSJT-X for WSPR?

mine only trasmits. how do i set it up to receive?
matt chadders The WSPRlite is just a transmitter, it allows you to explore propagation from your location or investigate how your aerials are working by transmitting signals and then you look for reception reports at places like WSPRnet. The advantage of using a mini transmitter like this is that you can set it up almost anywhere and leave it running for days. However, if you also want to receive WSPR transmissions to support other Hams with signal reports then you will need to set up a receiver connected to a computer to receive and decode transmissions. If you have an internet connection you can then upload your results to WSPRnet.org. If you don’t want to tie up your main shack radio on this task I see a number of manufacturers produce receiver kits for WSPR.
TNX for a good overview !

just ordered mine 30 minutes ago
Excellent video, very interesting. F5VJC
You have a new fan (see how I made that about me?) . Great Video, I am convinced to try this. Music is startling. Not good for old people. 73s KH6SKY
Jim Sky Thanks...I’ve toned down the volume on later videos! Sorry about that :o)
Is this similar to aprs if so I might as well fuck with aprs on a HT and carry my smartphone along with qrp mountain topper radio with cw key then this garbage
Dan Baudelio No, WSPR is a very low power propagation analysis mode. You don’t have a QSO, it’s more like a beacon where you transmit your call and locator using, typically, >200mW and there are lots of receiving stations around the globe who upload their reports to www.wspr.net.
Why exactly all the spattering blood in your intro? Disgusting, tasteless.
avt The intro theme is called ‘Ink Splats’...I confess I’ve never thought of it as blood...that definitely wouldn’t make sense given the context of the videos. Thanks for the feedback.
Another way for people to become lazy with portable radio
