Hi Folks,
till now i 've used a Yaesu G-5400B Rotator interfaced with the Trakbox.
I have changed the Rotator with a Yaesu G-5500.
Since I have changed it, it seems that the Switch on the Trakbox that had to
switch ON/OFF the rotator to turn them manually, does not work anymore.
I mean if I switch it off to turn manually the rotators, they keep moving to
the park
Position after I made the movements.
Anybody can tell me if the connections on the back of the Control Box of the
G-5500 are the same of the ones on The G-5400B ?
If yes which could be the problem?
Thanks in advance.

Some of you may remember the Chicken Little Contest run by Alan a while
back.
I have taken another look at decay using the XATCOBEO satellite as an
example.
My first try at a program calculated the decay in early June 2014.
I am all but positive this is several weeks too soon.
On the other end of the spectrum SatPC32/WinAOS shows it up and running
well into 2084.
I am as positive as I can be that this is many decades too late.
Orbitron shows it still running on Sept 8 2014 but at an altitude of only
109km.
I believe this is a bit late as 160km is usually considered to be the point
of no return.
Calsky predicts decay on 14 August 2014 with a +/- of 15 days
Smart guy to hedge his bets with the +/- range.
DK3WN predicts decay on 31 July 2014
This falls into the +/- range of Calsky and since our own N8MH is an editor
on this site it is probably the closest.
With LEO satellites rapidly becoming as common as iPads they provide
interesting subjects for decay predictions
and possible Chicken Little contests.
Is there any formal definition/announcement of the actual decay or
are satellites like old soldiers and just fade away ?

Good evening,
It appears that the LituanicaSAT-1 FM transponder was off over North
America at 0121Z. Strong signals were heard from the FM morse beacon.
I will listen to my recording and decode the telemetry.

CW Telemetry beacon, as decoded by FLDIGI here in CM98 on the 6/2 0600z
pass. My rotor controller doesn't do flipped operation, so the 3rd
frame got trashed by the rotor needing to swing around as the satellite
passed through North. Some errors in the frames, but for the most part,
during the frame itself, the signal was full quieting. It seemed like
the very front of the frame (call sign?) was at a low power setting,
then jumped up for the main part, and then at the end a few dits,
seconds apart, at low power.
This was my second attempt (first success) at copying the beacon. Hope
this helps,
Greg KO6TH

Hello Tom,
the program WinAOS gives you a quick overview of the satellite passes in
the near future.
The program is not designed for long term calculations. It doesn't use
the SGP4/SDP4 model as SatPC32 and WinListen do but uses rather simple
calculation routines. Therefore use WinListen or the "Preview" function
of SatPC32 for more precise calculations.
