While ECHO is enroute to the launch site in Kazakhstan, here is a brief
report on activities leading up to ECHO's departure on 09 June 2004.
On 01 June, Chuck Green, N0ADI and Jim White, WD0E, teamed up to begin
reviewing the test procedures that would be run and making a plan for the
activities upcoming in the days ahead. During the next several days a few
minor harness changes where made and several run-throughs of the launch
site test procedure were accomplished.
Final close out work on the modules began on 04 June 2004. This involved
cleaning the inside of each module, putting RTV on every screw head and nut,
and securing wiring with cord and RTV. Also, the fuse from the main
computer board was removed and replaced it with a zero ohm resistor and the
Watchdog Enable jumper was replaced with wire. Chuck added, "After dinner I
worked on the solar panels. Each needs it's wiring added, it's connector
installed, and a thermistor added and wired. I finished one of the six
before it was midnight again." By 06 June, work on all six solar panels had
been completed.
07 June after spending some time troubleshooting a balky laptop used for
testing, the ground test software was moved to Lyle Johnson's, KK7P,
computer. Using Lyle's computer, ECHO passed its tests very well. By the
end of the day the last module was put on the stack and the wiring harness
installed for the final time. Chuck said, "I secured all the screws and I
replaced the coax in the chimney." The solar panels were packed for
shipping along with the magnetic rod and corner reflectors.
08 June we solved the mystery of Chuck's serial port. The umbilical cable
between the laptop computer and Echo was not wired correctly, and the ground
pin was tied to pin 8 rather than pin 9. So, going to launch, we now have
two independent laptops checked out with the umbilical.
The final checks the day before packing ECHO for shipping were discussed in
ANS-161 on 09 June.
