Re: There's no usable satellites

Hi Andras, I totaly agree with your point. To turn the "rudder" a little bit more into ham radio dx direction I designed several years ago a small CubeSat sized linear transponder. (Just google "LE005-R2" and you will find it). The idea was to make it off the shelve available for the Cubes, as it is quiet complex to design for students. Surprisingly the interrest from these Cube groups was/is very very low. (Most requests are from privat hams ! for using it on a mountains or balloon). CubeSat groups seem to prefer FM, AX25, and not to much difficult ssb stuff they can not use and test themselves. Most of these small sats are under the name off education, but in the background a huge business sector is available (just google "Cubesat shop" and enjoy). Because of this I believe the AMSATs none-profit status is a huge disadvantage, and it is very hard to get a HEO into orbit. AMSAT should have kept the RF payload (of a big satellite), and give away some spaces to universities, sharing the ham radio payload. Now the spaces are given away as separate small boxes (cubesats) that all have similar RF systems (FM and 1k2/9k6 AX25). Why not assemble the cubes all together as one big satellite, where AMSAT provides the common digital download payload + some extra linear transponder ??? In this way there is more space for university experiments, and the RF is done by people who have many experience in amateurs satellite radios. But best of all is that we have our own payload added. (Some less frequencies then AO40 but possibly in a MEO/HEO). Just an idea, 73 de PE1RAH, William Leijenaar > Gentlemen, > > I have spent too much money on an FT-847! > > I had better to buy a well equipped HF transceiver instead! > > There is practically no usable satellites -except for AO-7 and VO-52. > > The problem is that you can find always the same stations on them. > > F2IL is in my log about 300 times... > > Spending money on FM satellites were made according to long term plans > of IARU, ARRL and AMSAT which had been a dream of > handling emergency traffic using hand-held equipment and antenna -as far > as I know. > > Satellite activity is seriously declining! > > gl de ha6nn > Andras >

Monday Night NASA!
by Clint Bradford 31 Oct '11

31 Oct '11

PHILADELPHIA EAGLES TO HONOR NASA ASTRONAUT CHRIS FERGUSON DURING MONDAY NIGHT FOOTBALL NOV. 7 HOUSTON -- NASA astronaut Chris Ferguson will return to his hometown on Nov. 7 to serve as the Philadelphia Eagles' Honorary Captain during the NFL's "Monday Night Football" game. The Eagles are hosting the Chicago Bears at Lincoln Financial Field in Philadelphia, beginning at 8:30 p.m. EDT. Ferguson will be recognized on the field for his dedication to America's space program and his leadership commanding the final flight of space shuttle Atlantis. The 13-day mission marked the end of the shuttle program's 30-year legacy with Atlantis' touchdown on July 21, 2011. Ferguson, who joined the astronaut corps in August 1998, is visiting Philadelphia to spread NASA's message about the importance of space research and exploration. Before the game, Ferguson will visit the Please Touch Museum from 1 to 2:30 p.m. While at the children's museum he will participate in story time and sign autographs. To schedule an interview or for more information about Ferguson's appearances in Philadelphia, contact Tammie Letroise-Brown at 281-483-4942 or tammie.r.letroise-brown(a)nasa.gov. For more about NASA and its programs, visit: http://www.nasa.gov For complete biographical information on Ferguson and other astronaut information, visit: http://www.nasa.gov/astronauts -end- Clint Bradford clintbradford(a)mac.com

RAX-2
by Carl Rimmer W8KRF 31 Oct '11

31 Oct '11

Using Object C, E, and F, I did hear RAX-2 this morning but could not copy the data. Since I do not have an external TNC, I used the TS-2000 internal TNC. For those who have the TS-2000, I set Menu 46=Main; Menu 47=9600 bps; Menu 48=TNC Band; and Menu 55=On. I then used HyperTerm to connect to the TNC and did a RESET. I turned Kiss=On, Mon=On, MCON=On, and MCOM=On. I disconnected from Hyperterm and ran RAX_Serial_to_TCP.bat; I then ran RAX_GS_Client.bat. The Summary Panel is being displayed and I received not errors from either BAT file. I have the Mode set to FM on 437.345 MHz. I had to manually tune (from 5 KHz above to 5 KHz below the center frequency during the pass) since the TNC is using the COM port negating any CAT control. As I said before, I am seeing a very strong signal on my S-meter about every 20 secs. Since 9.6K sound much like noise, I can not really distinguish the data from the noise. Anyone have a suggestions as to why I am not displaying data? -- *Carl W8KRF*

To show you how uncertain this whole thing is---this morning I went to Space-Track and got a set of keps for these birds. Most were dated with "day 304". Just now, I went for another "fresh" set--they had gone back to "day 303" and when compared to the previous set from early this morning, and all the AOS times are about 2-3 minutes different!
