On my lunch break i was able to make a QSO with VE3BSB James in his car running. It was my first
QSO with a mobile station on a Transponder type satellite in SSB. I was testting an old KLM 2M 14C
on the downlink and i was using a 7.5' dish on the uplink. The power setting was at 0 on my FT-847.
The hic with low TX power make us often unhearded by some stations and i have to often crank up my
power to be able to make the other party hear me. But on this QSO i was able to keep my power at 0
or near that as the 847 still transmit some wattage my last preamp knows it...
The medium is the message...The content is the audience...;)

2006 AMSAT North America Space Symposium
6-8 October 2006, Foster City, California
Call for Papers: Final Call
Invitation: Speakers are invited to submit and
present papers dealing with the science of
Amateur Radio Satellites and associated
technologies for the AMSAT 2006 Space Symposium.
The Symposium will be held at the Crowne Plaza
Hotel in Foster City, California approximately
10km south of San Francisco International
Airport. This is an annual Symposium, however the
2005 Symposium was cancelled due to hurricane
damage caused by hurricanes Katrina and Rita.
Speakers originally scheduled for the 2005
Symposium are invited to re-submit papers for the 2006 Symposium.
Topics: Recommended topics include but are not
limited to the following categories:
· AMSAT P3E
· AMSAT Eagle
· Microsatellite Projects
· Cubesat and Nanosatellite Projects
· Attitude Determination and Control
· Digital Modes
· Education and Outreach
· Launch Opportunities
· Status Reports
· The AMSAT Board of Directors will meet on 5-6 October.
· The AMSAT Annual General Meeting (AGM) will be held on 6 October.
· AMSAT International will meet 8 October
· The IARU Satellite Committee will meet during
the Symposium and will hold a public round table
discussion on frequency coordination on 8 October
· The ARISS International Delegates Meeting will be held on 9-10 October
· "Birds of a Feather" sessions (BOFS) will be available on request
Deadline: Applications for papers must be received ASAP. Papers must be
submitted no later than 12 September 2006.
Procedure: The planning committee has created an
online registration system where you can submit
your abstract and track it. Using this system you
will allow you to submit your paper and any subsequent changes online.
Visit the 2006 Symposium Paper Registration webpage for instructions:
Contact Emily Clarke, N1DID for additional information or Jean Fletcher
KG6IAK for additional information
Venue: See the 2006 Space Symposium web page for
additional information about the venue.
Does anyone know what percentage of a day or orbit the echo transmitters
I've been thinking about the battery depth of discharge issue.
Being that they are as a whole 4 amp hours, a 10 percent discharge would
equate to about 1.6 amps for one quarter of an orbit on-time.
According to drew, the transmitters are drawing about .8 amps.
I hope people are viewing depth of discharge as a function of amp-hours
more than voltage ( I realize also important ).
Any comments are welcome.
Thanks, pat n2oeq
Hello Delmarva residents:
We are looking for people to participate in an AMSAT project at U. Md.
E.S., in the Wallops Island area, and at a new facility in Pocomoke,
Md. near Wallops. This is a satellite construction project for the
amateur satellite service. If you are interested in participation,
live close enough to give us time on a regular basis, please reply to

Yes the USB to serial adapters work, but they are not all equal. I have
found the ones with the FTDI chip and drivers to be the most reliable. In
my computer upgrade I installed a USB to serial port and also got a PCI to
dual serial port card (very cost effective).
The new computer came with no serial ports, but I am using three serial
ports for digital work.
First one for 9600 bps modem to WiSP software.
Second for SatPC32 to LVB tracker and rotor control
Third for SatPC32 to FT-847 for Doppler tracking.
Granted, I had to install/uninstall theUSB/serial driver about 8 times
before it worked. The PCI card with two serial ports worked the first time.
Once I got the drivers installed correctly I have had no trouble and used
the serial ports with multiple devices without a problem for the last month.
