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.
The USA257 (CLIO) NORAD 40208 would be an option. It is located at 21.7E. I couldn't verify whether it was equipped with an X-band.

CLIO
1 40208U 14055A 20180.20928624 0.00000000 00000-0 00000-0 0 06
2 40208 0.0961 120.8977 0014997 230.4577 129.3781 1.00281279 05

Aber leider, die letzte TLE (von McCants liste) ist von Juni 2020, d.h. seitdem wurde CLIO nicht mehr beobachtet und gemeldet.
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 | Intelsat

Intelsat announced a service outage on the Intelsat 33e satellite, which is affecting customers in Europe, Africa and parts of the Asia-Pacific region.

satesco I asked Flysat to make a Ovzon-3 entry and he moved 3 of your previously reported IS-33e transponders there!
Home - FlySat Satellite Chart

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

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

My scan. I can't get 10711 H and 10727 H to lock with manual SR.
I think more beams are at play.

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.
