All, I am pleased to announce that NASA has just released a new 4D ionosphere tool that can benefit the ham radio community. To explore the ionosphere and for more information on this outstanding modeling system, please go to the following web sites: The vodcast on the 4D ionosphere www.nasa.gov. http://www.nasa.gov/topics/solarsystem/features/4dions_feature.html A downloadable version that includes a sound bite on how ham radio operators will benefit from this model: http://svs.gsfc.nasa.gov/vis/a010000/a010200/a010208/ Enjoy! 73, Frank Bauer, KA3HDO

TAPR has ROMs and the image is readily available if you can program EPROMs. Also check the battery to see if is still alive. If you need parts let me know as I still have most everything in the kits. After making these changes let me know your results. 73, Jack - WA4EJR

Delfi-c3 shutting down and rebooting.
by Charles Reiche 06 May '08

06 May '08

I captured audio of the Delfi-C3 pass this evening around 02:43 UTC on May 6 on 145.930. I was hearing some odd formations of the data coming from delfi-c3, I was synced and recieving packets at the time. Shortly after this the satellite shut off and restarted a few seconds later, sending more data. Again after about another minute I heard the strange noises, then the bird shut off.... a few seconds later it came back only to an idle, and once again shut down, this time for the rest of the pass. Hope this description and the following links to the audio can help. http://www.n3crt.net/amsat/delfic3/delfic3_050608_0240Z_reboot_and_idle.mp3 http://www.n3crt.net/amsat/delfic3/delfic3_050608_0240Z_reboot_and_idle.wav http://www.n3crt.net/amsat/delfic3/delfic3_050608_0240Z.txt Charles Reiche N3CRT FN20XW IC-910h ~80ft 9913 into M squared 2m7 yagi fixed on the horizon and horizontally polarized.

AO-51 mode L/S QSB
by Piero Baudino 06 May '08

06 May '08

Hi all, just worked AO-51 in mode L/S over EU starting at about 19.45 UTC. I can notice a very deep qsb from about S3 (converter noise) to S9+20. I can't remember a so deep qsb in the past, 1-2 years ago the sat in this mode was with very "stable" signals. Is AO-51 not well stabilized ? Any info from command stations ? My working setup is: RTX: Icom IC-910 converter: DB6NT 2,4 Ghz to 144 Mhz, 0.43 dB NF antenna: grid 70x70 cm. oriz. pol. Best '73 de Piero IZ1ERR
