Since today, Intelsat 25 is leaving 31.5°W towards the West, next location (or EOL) not known yet.

Quote from qwer

...and now only the "last two ones" and "single appeared" in spectrum are lockable with linear LNB from my place... others are in "disturbing area"...

AT1 had 27 active transponders (according FlySat list), while AT2 has just 16 available.
Probably soon a linear LNB won't give much joy any more!

Here (with linear) I can't get a lock on any one anyway.

Supposedly Syracuse 3B is in graveyard orbit since a week, already beyond 60°W, can you confirm? qwer

This old satellite has moved to 27.1°W, with 3.0° inclination.

Lacking a frequency plan, I just assumed Chinasat 9C would be similar to Chinasat 9 (which is still nearby at 92.4°E with a little inclination).
The choice in these cases, is show something that is probably mostly right, or show nothing at all!

Shows 12520 has been on Chinasat 9C in two polarizations until August 2025.
No details any more, also no backup found on Internet Archive...

Intelsat 22 will relocate, to support the Australian Defence Force with its UHF payload.

Ah sorry, I overlooked it is T2-MI.

12245 H used to be easy here, and mostly the only in the 11.7...12.5 GHz range, but has become impossible several months ago.
Probably nearby circular transponders appeared or became stronger.

Instead 11727 V 29335 is locking now (5.5 dB), but it seems empty?

AMC-14 is still moving about 0.1°E/day, today will cross the belt near 33.3°E.
The last manoeuver was in October 2025. I wonder if there is still some transponder activity.

Edit: nothing found during belt crossing, not even TT&C at 12695 or 12699.

He told me almost 2 years ago already trying to sell the site because of a health issue.
With no success until now apparently.
My impression after many years corresponding it was a full-time job to maintain the site.

Interesting, I thought N. Korea had just one TV channeI, and also didn't know it moved from Thaicom to Express satellites.
Tried to translate the names:
1: Central TV, 9: Ryongnamsan TV, 17: Mansudae TV, 25: Sports TV, 1000: Radio 1, 1100: Radio 2.

Television in North Korea - Wikipedia

en.wikipedia.org

The translate app said "Lazio" but I assume it should be "Radio".

4192 MHz must be from a normal transponder, not TT&C.
If linear (vertical), it's IS-25. If circular, it's IS-904.

Surely the friendly parameters are to compensate the loss during inclination, for fixed dishes.
These are the (all locked) values now during 0° inclination, with 1.2 m and Dr. HD F16:
11060H 14.5 dB, 11265V 4.0 dB, 11345V 3.7 dB, 11385H 3.5 dB.

I had forgotten that AMC-14 relocations always are done very slowly.
Making me think control of this satellite was finally lost.
But a manoeuver happened a week ago, reversing the East motion to slowly West.
AMC-14 appears to settle now at 30.6°E, with 23.7° inclination.
Below shows the motion since 20 September.
Update 6 Nov 2025: still not completely settled, near 30.25°E now.

SBIRS-Geo 5 has moved to 94.0°E meanwhile.
20.9°E is now occupied by SBIRS-Geo 4 that arrived yesterday.

51.8°E has SBIRS-Geo 1, and 49.8°W has SBIRS-Geo 2.

4°W is mostly shaded on my dish, only very strong signals (like from 5°W) may make it.
Thanks for checking this in-orbit testing!

I also didn't find a frequency plan (as usual nowadays).
On my web page, added the "3" for the 11.2...11.45 GHz band, and removed the "?" for 11.45...11.7 GHz.
Marcus_21 found carriers near 11160 V, so a "2" should also be added probably.

Dror-1 is centered at about 3.98°W for the last 3 days.
It may well aim for 4.0°W exactly, but it takes a few weeks to confirm that.
Amos-7 (which left in March this year) was at 3.88°W.
Perhaps this means, Dror-1 indeed will replace Amos-3 at 4.13°W (launched in 2008).

These Invacoms were the best choice about 20 years ago, before the IBU's existed!
The IBU's perform better for most (also in my case, when they came out back then).

AMC-14 stayed at 17.5°E since my post above, but since the beginning of May 2025 it appears control is lost, and the satellite started drifting to the East. Now it's near 19°E.

s-band Sorry I also have trouble to interpret the ITU names.
Only thing I sometimes do, is search for other satellites of a series, to figure out what the ITU name should probably be like.
There was a site comparing the names, geostationary.cz, but it seems offline. Maybe archive.org still has some content.

I receive these 6 transponders too, over 12 dB with 1.2 m in rainy weather.
This map seems to fit best, it's on the Amos site: https://amos-spacecom.com/satellites-amos-4/
