July 4, 2004
Testing and checkout of ECHO is continuing. ECHO's TX0 transmitter
can be heard transmitting 9600 baud FSK telemetry on a frequency of
435.150 MHz. Command Stations are varying the output power of the TX0
transmitter. During times when the satellite is in view of a command
station the power is likely to be set to a higher level, somewhere between 1
and 2 watts, depending on power budget and received signal strength. During
the remaining time the power will be about 0.6 watts.
The command team continues to load software into Echo and as of Saturday, 03
July 2004 the file system and Whole Orbit Data software are operational.
Packets received which contain "LDR" are replies by ECHO to command stations
as they upload software to the satellite. The next step in the commissioning
process is to collect Whole Orbit Data (WOD) from the satellite through
Monday night. This will allow a good look at telemetry data for a complete
orbit. WOD is needed to determine spacecraft attitude, configure the BCR,
and get a better look at the overall health of the satellite.
Lee McLamb, KU4OS, Senior Editor of the AMSAT News Service will be issuing
up dated bulletins over the next few days to advise you on the progress
being made during commissioning. At the proper time, when sufficient data
has been confirmed, Past President Bill Tynan will issue a bulletin giving
the AO-XX designation, updated Keplerian Elements will be issued as soon as
they are received.
MEANWHILE please DO NOT Transmit to the satellite - commissioning must take
priority. A bulletin will be released when the satellite is open for general
use.

Emily, W0EEC has created a website to allow the users of AO-7 to record
contacts, observations and use of the satellite more effectively at:
http://www.experthams.net/ao7
This includes the ability to log contacts.
Tim, K3TZ has written a program to decode AO-07 telemetry. The program can
be
downloaded at:

SO-50 SAUDISAT-1C
Catalog number: 27607
Launched: December 20, 2002
Status: Operational.
Uplink: 145.850 MHz (67.0 Hz PL tone) (See below for operating
procedures)
Downlink: 436.795 MHz
To switch the transmitter on, you need to send a CTCSS tone of 74.4 Hz.
The
order of operation is thus: (allow for Doppler as necessary)
1) Transmit on 145.850 MHz with a tone of 74.4 Hz to arm the 10 minute timer
on board the spacecraft.
2) Now transmit on 145.850 MHz (FM Voice) using 67.0 Hz to PT the repeater
on
and off within the 10 Minute window.
3) Sending the 74.4 tone again within the 10 minute window will reset the 10
minute timer.
