Hi, As part of our STEM outreach strategy we are making WOD available for off-line analysis. This is delivered as a .csv file which can be downloaded from the Data Warehouse by clicking on the link on the WOD page: https://warehouse.funcube.org.uk/wod.html The file is written at 23:59 UTC every day and contains the WOD for the preceding 24 hours. Please read the notes on the page regarding the times stored in the file. Enjoy! 73 Dave, G4DPZ On behalf of the AO-73 team.

Lesson for the New Year
by Mike Herr 26 Dec '13

26 Dec '13

The lesson for the New Year is to get out and check your antennas!. Lately I have noticed the satellite signals were not as strong as i like. The, the other day I am out side looking at the antenna. Hmm, I thought it was parked due north, seems a bit east of north to me. Checked, yep the control says it is due north. I shoot it with a compass, yep, it is east of magnetic north. I scratch my head a bit, wait, should be west of magnetic north. That night I check it against polaris, and finally admit, it is almost 40 degrees east of where it should be. That will make the antenna system not work as well as it should. So today the antenna is down and being realigned as well as some other delayed maintenance.. Should be back up and running in a week. So, it's a good idea to go out and check, is the antenna really pointing the direction you think it is... -- Mike Herr WA6ARA DM-15dp Home of The QRP Ranch

Re: Funcube-1 decoding

Interesting; This morning (10:55utc) during an almost perfect North --> South pass, 70 degrees max elevation, (using exactly the same station configuration as yesterday) Funcube-1: - did not show any variations wrt polarization (was a lot yesterday), only slow fading in overall strenth - had weak downlink (SNR much lower as yesterday, could see it even on the SDR display only as of 16 degrees ele.) Henk, PA3GUO -----Oorspronkelijk bericht----- Van: PA3GUO Using a 2x6 elements beam + pre-amp + an FCD, it is possible to decode packets down to just 0.7 degrees elevation. Rather impressive. Also I noticed that if I have other CPU intensive SW running (HRD) at the same time, nothing is decoded. Visually it all looks the same on the FUNcube-1 Dashboard, signal strenghts etc., but somehow it needs maybe more PC resources (memory?) for the actual decoding, because as soon as I closed HRD incoming packets got decoded, while before none of them was.

Delfi n3xt decoding
by PA3GUO 25 Dec '13

25 Dec '13

Delfi-n3xt decoded fine down to 5 degrees elevation using a 2x6 elements beam + pre-amp + FCD + SDR#. I like the Delfi-nx3xt decoding software (DUDe) a lot. Together with the RAX/Mcubed decoding SW (from James Cutler) this is the best out there for us (IMHO). Compliments to those teams! (due to the format Delfi-n3xt is easer to set up, as you don't need to have the TNC switch to KISS mode) Less tumbling as Funcube-1, I for Funcube-1 I need to switch polarity regular for strongest SNR, Delfi-n3xt is more stable (can leave it in the same polarization all the time).
