Last TLE for Amos-17 at 13.8°E was 31 October.
This *could* mean "they lost it", and the satellite is on its way to 17.0°E, or already there.


I still see both H & V beacon sigs at what still seems to be 13.8° East but both very weak compared to a week or so ago

Amos 17 is moving East very slowly,
Yesterday it was at 13.88°E
Today it is a @ 13.92 °E

Real time satellite tracking for: AMOS 17
william-1, why not interpret TLE's correctly? Said this before, TLE's are just a snapshot of the motion (orbit) at one time (epoch).
If you insist using n2yo.com: check the satellite details, TLE is at bottom: Technical details for satellite AMOS 17
1 44479U 19050A 19304.77569395 .00000082 00000-0 00000+0 0 9990
2 44479 0.0131 281.3588 0001722 299.1394 112.3924 1.00275901 938
The 19304 is the julian date, see for example: FREE Calendar Templates
304 is 31 October, much older than most other satellites, now with epoch of 3 or 4 November.

Well of course, a new TLE appeared!
1 44479U 19050A 19308.93913266 .00000086 00000-0 00000+0 0 9996
2 44479 0.0206 285.5666 0001677 298.5037 171.7275 1.00273752 985
And it shows Amos-17 still firmly at 13.80°E.

... some different activity observed earlier - both usual beacon freq up to normal strength today - the traversing frequency sweep is of interest.

... There is now considerable intermittent various frequency test activity going on now from Amos-17 @ 13.8° E - too quick to capture everything that's coming and going

... it now looks like constant stable lower level markers are now present at 3700 LHC & 3701 RHC

Amos 17 left 13.8°E testing location on 13 November, and arrived at 17.0°E on 16 November.

I'm monitoring the C band output all the time now Will and apart from the odd narrow signal ramping up around 3700 H and the H beacon ramping up to a higher than normal level just now - there's not been much else to report.

Hi william-1 and John,
there was an empty data signal on 4147 L 28000 3/4 DVB-S2 QPSK - lockable yesterday (see attached file) - but decreased (<3dB ) a short moment later.
Peak on 4147 L is still there, but weaker and no signal to analyze today.
PS: carrier was on 3613 L and R for a short time.
Best regards
qwer.
/edit: Nothing in Ku-band (2,2m).

No - absolutely zilch / nothing here - - the beacon is at a good level though ?? lol.
** As a matter of interest - if you look at the Africa Ku Band footprint map from the Amos site , have you any idea what the light purple & violet shaded areas are supposed to represent

Amos-17 Ku .... I 'Think' i am seeing random test carriers ramping up and down from Amos-17 on Ku high V.
** These are not all active at the same time - they are each active for approx 1 minute and then drop and re- appear on the next freq up.
12.709 V
12.712 V
12.714 V
12.716 V
12.719 V
12.722 V
12.724 V
12.727 V... - - and so on
