Satelliten
upplevs enligt en del rapporter svagare i signalstyrka numera.

kom ett intressant meddelande via e-post listan.
Again, I encourage you
all to research the power levels OUT at the
comparison times. That has to at
least be considered in the
discussion.
For example:
Power is
“watts” out

2009-11-25 17:41:51 oz7sat 0 0.361 0.744 7.581
<– 745 mW before the flip!
2010-01-15 18:45:31 oz7sat 0 0.437 0.462
7.892
Currently:
2010-02-09 17:19:06 oz7sat 0 0.452 0.475 7.752
<– 475 mW today!
We are running a few hundred milliwatts below what
we were running
pre-flip, and a good bit less than we were able to run a year
ago.
So you all may be seeing the difference between 600-850 mW and 475
mW.
It’s real.
Yes, the bird is aging, and we’re doing the best we can
to manage the
resources available on-board (the limits now are orbit and
battery
condition) . The full illumination periods in the last year or
two
have taken their toll on the batteries. What will be interesting is
to
see what happens when we return to periods of eclipse!!
Personally, I don’t
expect the situatio to improve, although it might
be that the batteries will
cool and some capacity will return. But
we’ll need it with
eclipses.

*Övrigt
Solens aktivitet ökar
stadigt.
Bra aktivitet på satelliterna och undertecknad har hört följande SM
stationer SM0NZY SM5CUI SM7BHH.
FO-29 i mycket bra form.
