A while back I posted a note for a friend I was trying to help where SATPC32 would not doppler tune his FT-847. SATPCISS worked fine and he was able to tune the radio using the UP/DWN buttons on the SATPC32 screen. We finally have figured it out. His radio is one of the very early FT-847's which did not allow the VFO to be polled. There was a mod being done by Vertex, but a call to them came up empty. They have not done a mod since 2000 and they have no parts left. So, any one know if the mod can be done somehow? 73, Mike, N1JEZ AMSAT 29649 "A closed mouth gathers no feet"

The first SouthAmerica - Europe SSB HO-68 contact

by Juan Antonio Fernandez

Yesterday evening 240110 at 2327z Piraja PS8RF at GI84ow and me EA4CYQ at IM78bw made a contact in SSB mode through HO68. I think it is the first SouthAmerica - Europe Contact of 7.477 Km. After that I worked Canada VE2DWE and several USA stations KB1RVT, K3SZH and KC9ELU 6.666 Km. far away. This sat works flawlesly, congratulations to HOPE-1 team. Juan Antonio EA4CYQ IM78bw 73s

Kenwood D7 Fullduplex handheld FS

by John Price

I have this radio to offer from the estate of a dear friend. His wife is asking our local club to help sell his equipment. Before we list this on eBay I thought someone here might wont to purchase it. The radio is in excellent working condition. There is a scratch on the display but it does not interfere with reading the display. I have two batteries that both seem to take a charge just fine. One is a PB 39 and the other is a PB 38. They are both included. Also the orginal wall charger from Kenwood is included. All the manuals are with it also. I do not have the box. I would expect this radio with included items is worth $260.00 including shipping to the lower 48 states. Others please inquire concerning shipping cost. Anyone interested in this rig please contact me direct.

OSCAR 27 is not AO-27

by OZ1MY

Hi all, This may be known to some of you - but it has given me problems sometimes. OSCAR 27 is a different satellite than AO-27. OSCAR 27 is catalog number 18361. AMRAD-OSCAR-27 (AO-27) (AKA EYESAT) is catalog number 22825. OSCAR 27 is in the Transit series of satellites (NAVSAT). Other satellites in this series carry the OSCAR name and a number. I had this problem at a summer course in satellite technology for students from many countries. I said to them that they could use the keps for AO-27 for a project. AO-27 has a nice nearly circular orbit :-) Then they used OSCAR 27 - and I did not understand the the difference in the expected results in the start. Some lists of keplerian elements use EYESAT for AO-27. If you Goggle OSCAR 27 you get a lot of hits that are really AO-27. Greetings from Copenhagen. 73 OZ1MY Ib

AO-7 DX

by ps8rf Piraja

Hello friends, Today in the 161.057 orbit of the AO-7 approximately 22:51 UTC our friend Joe, K3SZH, managed to maintain a short QSO with Francisco Ramirez, PY2OV. The distance between the two stations was 7738 km (4833 Miles). And with absolute certainty the QSO could be extended by a greater good distance. I have the recording of QSO. Soon I'll add the link to the video / audio. 73, Pirajá, PS8RF _________________________________________________________________ Sabia que você tem 25Gb de armazenamento grátis na web?

Re: [Sumbandila: 286] Temporary suspension of SO-67 service

by Mothibi Ramusi

Hello Jan, Has there been any test on the telecommunication payload? Regards, From: sumbandila(a)googlegroups.com [mailto:[email protected]] On Behalf Of Jan-Albert Koekemoer Sent: 25 January 2010 01:01 PM To: amsat-bb(a)amsat.org Cc: sumbandila(a)googlegroups.com Subject: [Sumbandila: 286] Temporary suspension of SO-67 service Hello There is little more than 6 weeks left in which to complete the outstanding commissioning activities on Sumbandila before operations are planned to be handed over in middle-March to the Satellite Application Center, who will then continue to operate the satellite on behalf of the Department of Science and Technology (DST) - owner of the satellite. Since our progress is currently hampered by the various SA-AMSAT payload activities, we have unfortunately no choice but to temporarily suspend this service on SO-67. We plan to have it "on air" again end-March / beginning Apr this year. We have so far successfully executed more than 320 payload activations since we started using the SA-AMSAT payload in Q4 2009.

Graph of eclipse/sunlight

by andy thomas

I've been looking at some cosmonauts' historic accounts of missions on the Salyut series of orbital spacecraft. Characteristically they have drawn a graph of the eclipse and sunlight times of the long duration mission. The vertical axis is time after EQX of the first orbit of the day (the entry into and departure from eclipse is marked on this axis in 5 minute intervals) and the horizontal axis is the mission day. The result is a graph in which lines extend horizontally conencting the eclipse times (both in and out), and they have characteristically filled in the darkness time with dark pen. On one print the light time has another contour with what appears to be sun angle. The graph has then been added to by showing the plan and actual activity on that mission day. I would find it interesting to compute a similar graph for a long duration mission of the ISS. But I have some difficulty. From a TLE I can do the following: *calculate first eqx in utc but can't find the time of crossing into eclipse without knowing the position of the sun and the position of the spacecraft in relation to the sun (Subsatellite point?). Does anyone have any idea about the calculation and data involved? It must have been a hand calculation carried out by cosmonauts, but once a simple program is written I could use excel to draw the graph. Maybe a standard predictor program can produce a data output that could be rewritten into excel? I'd need the eclipse times on the orbit following the first eqx of the day. I would appreciate any input, also any thoughts of why they would want to draw it (have only thought of observation and power). many thanks 73 de andy G0SFJ
