The US Naval Academy Satellite Laboratory announced a special ANDE 
Operations Event for the Tuesday, August 28 and Thursday, August 30
morning passes over the US East Coast. 

Bob, WB4APR described the operation plans, "On Tuesday, Naval Academy 
stuents will operate ANDE to gather statistics on the success rate 
of the APRS mission.  We invite participation, attended or unattended 
and request these guidelines be followed:
1) Tracking Base stations transmit at 5 minute intervals
2) 50W mobiles transmit at 3 minute intervals
3) 5W HT's transmit at 1 minute intervals

Bob reminds amateurs, "Please do not transmit more often, as it will 
mess up the statistics.  It would be helpful if you put your station 
info in your posit text so we could confirm the validity of the sta-
tistics of your transmit rate".  We recommend something like:
"Base=5min +10 dB"
"50W =3min w 5/8ths"
"HT=1min w 19" ant"

On Thursday, the Naval Academy may activate the packet to voice 

ANDE operates on 145.825 MHz simplex and responds to packets that
are addressed VIA APRSAT or VIA ARISS.  For more information please

The 26th Annual ARRL/TAPR Digital Communications Conference to be held on
September 28-30, 2007 in Hartford, CT will feature topics of interest to
amateur satellite operators. AMSAT Director and VP Engineering, Bob 
McGwier, N4HY, will have several presentations.

On September 30 Bob will present the Sunday Seminar, "A Stroll Through 
Software Radio, Information Theory, and Some Applications."  Software 
Radio will be the main theme and a package of tutorials and give away 
software will be a part of the seminar.  

The Software Defined Radio linear transponder system in AMSAT's spacecraft 
will be discussed. Some necessary information theory will be discussed 
with examples with the goal of leaving the attendee with a working know-
ledge of the practical use of this theory in thinking about communication 
systems. As time permits, Bob will show some software radio systems from 
the $30 softrock40 to GnuRadio/USRP doing multi megabit per second OFDM 
on the air and then a technical description of the Flex5000 and DttSP 
will be given.

Additional Software Defined Radio topics among the digital offerings
at the conference include:

+ The FSM Virtual Radio Kernel: Why, What, & How (In That Order);
  Frank Brickle, PhD, AB2KT

+ AMSAT¹s Phase IV (lite)?; Bob McGwier

+ On A Method for Automatic Image Balancing in IQ Mixer Based Software 
  Defined Receivers; Bob McGwier, N4HY

+ TPSK31: Getting the Trellis Coded Modulation Advantage;
  Bob McGwier, N4HY

+ The Flex 5000 Software Defined Transceiver;
  Gerald Youngblood, K5SDR

And also known to AMSAT members, Bob Bruninga, WB4APR has written a
paper for the conference: The APRS Local Voice Repeater Initiative.

+ Satellite operators can find the latest information about New Zealand's
  KiwiSAT at http://www.kiwisat.org which is upAugust 26d weekly. Terry, 
  ZL3QL wrote, "The project is well down the track to completion and this 
  page will give a good idea of what is still required."  He invited ama-
  teurs to check out and respond to http://www.kiwisat.org.nz/funding.html.

+ Matthias, DD1US invites satellite operators to visit his "Sounds from 
  Space" site at http://www.dd1us.de.  He has posted a collection of 
  recordings from various space objects. Most of them are ham radio 
  satellites and space ships.

+ NASA's two venerable Voyager spacecraft are celebrating three decades 
  of flight as they head toward interstellar space. Their ongoing odysseys 
  mark an unprecedented and historic accomplishment. Voyager 2 launched on 
  Aug. 20, 1977, and Voyager 1 launched on Sept. 5, 1977. They continue to 
  return information from distances more than three times farther away than 

+ Zarya, the International Space Station's first component to go into 
  space, passed the 50,000th orbit mark this week on August 14. Zarya, 
  which is Russian for "Sunrise", was funded by the United States and 
  built by Russia. It launched atop a Proton rocket from Baikonur 
  Cosmodrome in Kazakhstan on Nov. 20, 1998.

+ An interactive guide to the International Space Station can be found
  on-line at: http://www.nasa.gov/externalflash/ISSRG/index.htm.

+ Google Earth software has now added the capability to view images of
  the sky.  Using the new "Sky in Google Earth" feature you can zoom in
  Hubble images.  Version 4.2 of the software at http://earth.google.com/
  contains the additional sky watching features.

+ While not quite amateur radio related, many hams enjoy learning about
  scientific work in other fields. The events taking place today at CERN's 
  Large Hadron Collider outside Geneva, Switzerland by one of the world's 
  largest assembled teams of scientists attempting to discover what is 
  considered the "Holy Grail" of particle physics, the Higgs Boson, and 
  recreate the conditions that existed a few seconds after the Big Bang 
  are highlighted in an interesting on-line BBC video at:
