Hi John...
Thank you for answering my questions, I now have an understanding of your basis for believing that the timer no longer functions or is random at best.
I am now willing to wait quietly for the Eclipse-free date. Has it been estimated or calculated?
Many thanks!
Roger WA1KAT

Hello Kevin, Roger, Kevin, I'm glad you dug out one of my earlier posts re: the timer issue.
(Roger, I'm the chappie the >>>>'s are referring to in the following
post).

Like I already mentioned ... and Kevin repeats ... it's no big deal, lets just wait and see.
If I'm wrong, I'm wrong, no harm done. Lets not waste anymore bandwidth on it ok? ... however, Roger, it would be impolite of me not to answer you questions.
I would love to hear your version of what will happen when there is a
lack
of eclipse for the satellite
As I previously mentioned, I would expect the satellite to remain in the mode it was in as it came out of eclipse. As I also mentioned, I would
stand
corrected if that doesn't happen ... ie ... it is not !!! a big deal and if I'm wrong ... I'm wrong ... no harm done.
Please note that I am *NOT* the first AO-7 operator to come to this conclusion.
Are you saying AO-7 went up without a timer?
No ... I'm not saying that, I am saying that the designer and constructor
of
the apparatus in question told me that the components used were not as stated in the 1974 newsletter.
<Are you saying the timer is no longer functioning?
I have said earlier and am saying now !!! ... that the timer functions PERIODICALLY ... as can be seen by the entries in the log for the last 3 years ... (monitored by myself).
Perhaps a re-read of my original mail might be of value here?.
The intent ... to make a simple observation for the benefit of those who don't necessarily follow the daily "doings" of AO-7 like I do.
Nothing more - nothing less. No form of criticism to anybody or anything offered or implied.
how is it you determined that the timer is no longer "in the mix?"
By monitoring the satellite daily for the last 3 years.
If AO-7 comes out it's "final" eclipse in Mode A, will it stay there?.
Who knows !!! ... I certainly don't. I think the real experts all agree
...
it *random* ... the reasons are many and varied ... *NOT* just temerature and age.
CC'd to interested parties.
