SB SAT @ AMSAT $ANS-090 01 AO-51 Schedule - April 2008

AMSAT News Service Bulletin 090 01 From AMSAT HQ SILVER SPRING, MD March 30, 2008 To All RADIO AMATEURS BID: $ANS-090 01

The first week of April, AO-51 exits full illumination and our power budget will shrink considerably The length of the eclipses will increase throughout the month, and we'll have to closely monitor our power situation The schedule reflects this, as the BBS will be active throughout the first two weeks of the month Additionally all AO-51 transmitters will be shut off on March 31st for a special Whole Orbit Data collection before full illumination ends

As the month progresses we will schedule some time with the L/U BBS switched to a L/U repeater on an "as available" basis Watch the webpage and ANS for announcements with further details

SB SAT @ AMSAT $ANS-090 02 Satellite Demo Videos

AMSAT News Service Bulletin 090 02 From AMSAT HQ SILVER SPRING, MD March 30, 2008 To All RADIO AMATEURS BID: $ANS-090 02

Robert Davies, KI4HXT, has produced a Windows media video showing how to work AO-27 Dave Jordan, AA4KN does the actual satellite demonstration during the 2008 Orlando Hamcation Dave describes the Doppler shift that will occur during the pass, makes a number of contacts during the pass, then talks about setting up the Kenwood TH-D7A hand held for analog satellite operation Drew Glasbrenner, KO4MA was doing a simultaneous demonstration and has a cameo appearance describing the arc of the upcoming pass This is about a 20 minute video

Bob McGwier, N4HY also has a video recorded in February that talks about the AMSAT Engineering activities during the next few months Good information about a number of activities that are taking place this year This is a 10 minute video

Videos can be found at http://www ki4hxt com/id5 html

Thanks to Robert for hosting these

We are working on additional videos, stay tuned

SB SAT @ AMSAT $ANS-090 05 KiwiSAT Update

AMSAT News Service Bulletin 090 05 From AMSAT HQ SILVER SPRING, MD March 30, 2008 To All RADIO AMATEURS BID: $ANS-090 05

KiwiSAT will now carry an additional special beacon which, it is planned, will be used by radio amateurs around the world to collect data on atmospheric aberrations to assist with finite information collection directly associated with Global Warming concerns and Carbon Balance monitoring

Details have yet to be finalized however the KiwiSAT structure has been modified to incorporate a second 70cm monopole mounted on the Z- face A high level of filtering has been incorporated to minimize any desensitizing of the on-board 70 cm receivers The operation of the beacon will be switched as required but will normally be ON for whole orbit data collection

The KiwiSAT linear flight transponder is currently transmitting from the Whangaparaoa area with beam antennas pointing South

Transponder is inverting type to compensate for Doppler shift when in orbit * Transmit Power is 2 Watts PEP * Beacon frequency is 145 885 MHz * Uplink is from 435 265 to 435 235 MHZ LSB (note the sideband) * Down link is from 145 850 to 145 880 MHz USB A test transmission on 435 2544 LSB came out at 145 860 USB

As it's a linear transponder 30kHz wide, any mode can be used, but FM is discouraged (but not banned) Amateur stations are encouraged to try out the transponder Try to better the previous distance of record of 292 km previously achieved with the prototype transponder (same location/antenna)
