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
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!
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.
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? 73s
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.
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.
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.
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.
