I am the owner/operator of WA5DJJ'S ALL BAND HF QRSS/WSPR GRABBER. I am trying to make it easier for those who are using the QRP Labs U3S to be able to know when they would have the opportunity to send a QRSS signal to my grabber. So I have made my QRSS receivers wide banded and located them about 200Hz below the WSPR frequencies. Then I made my Raspberry Pi's take the receiver audio and do two things: make the normal LOPORA v5 QRSS 20M grabber screen along with a 24 hour grabber screen. the second thing I did was load WSJT-X v 1.9.1 and have it use the same audio stream that the QRSS grabber is using. I am sending those data outputs to to be displayed on the maps. If you see your call on my WA5DJJ WSPR map. there is a really good chance if you made your U3S also do a DFCW transmission on the QRSS frequency after your WSPR transmission IT WILL ALSO SHOW UP ON THE GRABBER SCREEN.

This will give QRSS many more signals for our grabbers and keep your U3S warmed up for the next WSPR RUN. I now have QRSS/WSPR grabbers on 160M, 80M, 40M, 30M, 20M, 17M, 15M, 12M and 10M. I am located in Las Cruces, New Mexico and would really like to see my grabber screens full of QRSS signals. I really do need a lot more continuous dedicated QRSS transmissions 24/7. I work very hard to make my SUPER GRABBER the best it can be. Now I can watch both QRSS and WSPR modes in the hope of even making my grabber better.

So if you can see your way clear to give an extra QRSS transmission on any of the above band. I would be grateful. My grabber's URL is For frequencies to put in your U3S setup data consult my website for the frequency ranges.

Thank you for your time, Send me a signal, take care and have fun.
