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/

SBIRS-Geo 2 has been relocated from 38.0°W to 49.8°W.

Dipollänge ist nicht so ganz wichtig, Reflektor und Direktor(en) beschränken die Bandbreite, die für E2...E4 relativ Gross sein muss (für ein Yagi).
Aber ist der Spass in Band I nicht schon lange vorbei?
In Band I gab es neben Es (Sporadic-E) und F2 ab und zu auch Tropo überreichweiten, hier die Deutschen die ich in die 80'er fotografiert habe! -
I don't think the frequency plan posted above is correct, because it doesn't match the existing transponder mapping.
Instead, this provisional plan made by Marcus_21 based on in-orbit testing at 50°E makes more sense. -
According both Lyngsat and Portal BSD, the only analog still active is 3730 V TV Verdade.
-
By the way, recent articles say that testing at 50°E is finished finally, and 6A should move to 42°E soon.
Turksat 6A left 50°E and is on the move, near 48°E now.

Der USA257 (CLIO) NORAD 40208 wäre eine Option. Er befindet sich auf 21.7E. ob der mit X-Band ausgestattet ist, konnte ich nicht verifizieren.

Zudem bewegte CLIO sich damals langsam nach Osten, also jetzt könnte CLIO irgentwo auf dem Clarke-belt sein. -
I still don't know what non-inclined satellite this can be, other than Yamal-601 having "secret" X-band payload.
Turksat 6A at 50°E has X-band payload, but was launched July 2024 and can't explain s-band finding in 2023.
By the way, recent articles say that testing at 50°E is finished finally, and 6A should move to 42°E soon. -
My 10805 H is spill-over from 62°E, giving almost 19 dB when pointing there.
-
More peaks appearing, but only 2 locks.
-
Quite different dB levels here in NL.

All 3 found a new location.

With 60°E IS-33e broken into pieces, I looked at this nearby position.
Is this 12271 V new, and the first signal in high-band of IS-39 maybe?
Looks strong in spectrum, but not really locking, had to do many attemps.
This should be Steerable 2 beam according frequency plan.Edit: another unlockable peak just appeared near 12455 V.

Since October 19, IS-33e failed and probably can not be recovered.
Intelsat Reports IS-33e Satellite Service Outage | IntelsatIntelsat announced a service outage on the Intelsat 33e satellite, which is affecting customers in Europe, Africa and parts of the Asia-Pacific region.www.intelsat.com -
satesco I asked Flysat to make a Ovzon-3 entry and he moved 3 of your previously reported IS-33e transponders there!

These AEHF satellites are not only hopping frequency, but also hopping their location quite often!

Yes, 10805 H was 62.0°E, I get the same 3 transponders on 62.0°E as you posted, just 2 dB less.

Since 59.7°E Ovzon-3 is co-located with 60.0°E Intelsat 33e, probably Ovzon-3 has frequency ranges that IS-33e does not have.
These are 10700...10950 and 11200...11450 MHz. I found 3 strong data transponders there, and a few weak unlockable ones.
10852 V 40000 ACM/VCM 8PSK 8/9
11262 H 64000 ACM/VCM QPSK 1/3
11387 H 64000 ACM/VCM QPSK 1/3
The 0.3° difference is enough to distinguish between the two, I'm pretty sure these 3 come from Ovzon-3.
