  KE6QMD - Morehead State University
+ Implementation of Deployable Solar Panels on a 1U CubeSat - Abhishek 
  Bajpayee - University of Louisiana

These videos can be seen at
http://www.ustream.tv/channel/CubeSatWorkshop/v3

Check the website for video of later presentations covering a D-STAR 
cubesat OUFTI-1, GENSO and Lunar Lander/Orbiter CubeSats which are

Swiss Amateur Radio Cubesat TIsat-1 Ready for Launch

AMSAT News Service Bulletin 115.04

To All RADIO AMATEURS
BID: $ANS-115.04

The Swiss Amateur Radio CubeSat TIsat-1 built by students in Ticino 
is ready for launch from India later this spring. TIsat-1 is to be 
launched on the PSLV-C15 launcher from the Sriharikota Space Center 
(SHAR) in India. It will go into a 670 km sun synchronous orbit with 
an inclination of 98.5 degrees.

The radio communications system is based on the Alinco DJC-6 dual 
band hand held transceiver. Downlink power will be 400mW on 437.305 
MHz. An uplink will be at 145.980 MHz. TIsat-1 will send its call 
sign HB9DE in CW and transmit AFSK telemetry from its on-board
experiments.

Experiments are planned for:

+ Monitoring of the durability of exposed thin bonding wires, PCB 
  tracks and lines (Atomic Oxygen effects).
+ Verification of the system fault tolerance scheme including 
   algorithms for error detection and correction both for on-board 
   memories and for communication.
+ Acquisition of spacecraft environment and operating data.
+ Redundancy in the key systems in order to resist space environment 
  induced effects. The critical hardware functions were replicated and 
  implemented with different technologies.
+ Careful hardware and software design taking care of latchups and 
  single-event upsets.
+ Smart self-adaptive software management scheme based on techniques 
  stemming from Artificial Intelligence.

This week Mani, VU2WMY Secretary & Station-In-Charge of the Upagrah 
Amateur Radio Club VU2URC at the India ISRO Satellite Centre sent a
request on behalf of the Hamsat VO-52 Operations Director.

To commemorate the milestone of Hamsat's VO-52 5 successful years in 
space on May 4 the India/ISRO team plans to publish a 'Comprehensive 
Performance & Utilization Report' of the VO-52 Transponder based on
user feedback from around the world. Information specifically request-
ed by ISTRAC for the report includes:

1. PERFORMANCE of the HAMSAT TRANSPONDER as _perceived by the users_ 
2. COMPARISON of the HAMSAT Transponder with her CONTEMPORARIES 
3. Details of SATELLITES providing SIMILAR SERVICES 
4. Approximate NUMBER OF USERS of HAMSAT in _India / over the globe_ 
5. GROWTH of HAMSAT USERS, since launch 
6. Approximate HAMSAT TRANSPONDER UTILISATION (transponder interaction 
   period) over the globe (transponder is ON always) 
7. Any more INTERESTING INFORMATION on HAMSAT

Send your feedback to Mani, VU2WMY at wmy at isac.gov.in or 
vu2wmy_mani at yahoo.com.

SA AMSAT Space Symposium Announces Cubesat Development

SA AMSAT announced at their recent Space Symposium held at the 
University of KwaZulu-Natal that it would be building its own 
CubeSat.

The project will involve radio amateurs, students and learners.
At this stage the project will start with inviting input from 
radio amateurs before the final payload is decided on, and pro-
ject teams will then be set up. If you are interested in becoming 
involved, you are invited to send an email with your contact 
details and areas of expertise to saamsat at intekom.co.za.

The currently proposed payload will include a transponder with a 
30 kHz bandwidth, a telemetry beacon and science projects.

Arecibo EME Wrap Up

BID: $ANS-115.07

While not strictly amateur satellite related, another aspect of 
amateur radio in space includes EME operations. Many amateur sat-
ellite operators participated in the recent EME test from Arecibo 
and may be interested in this.

Joe Taylor K1JT wrote to the EME community on the memorable KP4AO 
amateur radio moon bounce operation from the Arecibo Observatory 
in Puerto Rico, "Many thanks to all stations we worked from KP4AO 
-- and our apologies to the many more who called without completing 
a QSO. The Arecibo telescope's short moon windows were frustrating 
for all, ourselves included."

Joe descibed the "wall" of stations calling as simply incredible. A 
rough estimate suggests that we may have worked something like 20% 
of the callers potentially workable on SSB, 10% of those workable 
on CW, and only a few percent of those workable on JT65. I guess 
we'll have todo it again, in due course.

The KP4AO log shows nearly 240 completed QSOs with some 57 DXCC 
entities, in a total of 8 operating hours. The team made recordings 
of the whole 432 MHz EME sub-band for for most of the time KP4AO 
was on the air. In due course it will be possible to "tune the band" 
carefully, many times, picking out callsigns. 

Joe continued, "Here's a request for all ...

1. If you worked us with a setup significantly smaller than is 
   normally required for EME, please send me a short note describing 
   your antenna, receiver, and Tx power to joe at Princeton.EDU

2. If you copied us with a small setup, please send me details on 
   your antenna and receiver.

I know we worked and were heard by some pretty small setups, and I'd 
like to document some of them for a write-up in QST."

Members of the Arecibo Observatory Amateur Radio Club who constructed 
and operated the KP4AO station for this event:
Angel, WP3R
Pedro, NP4A
Angel, WP4G
Jim, WA3FET
Joe, K1JT
Additional guest operator: Pat, AA6EG

The WSJT software for operating JT-65B by K1JT can be downloaded

Many thanks, and see you on the moon!

In addition to regular membership, AMSAT offers membership in the
President's Club. Members of the President's Club, as sustaining donors
to AMSAT Project Funds, will be eligible to receive additional benefits.
Application forms are available from the AMSAT Office. And with that
please keep in mind the lament of the fellow who didn't pass his exam, 
"I'll never take another ham radio code test," Tom said without remorse.
