upcoming launch amos 4 65e

Updated TLE confirms the sat is in IOT position already: n2yo.com/?s=39237
It is time to hunt for the test carriers
 
Good luck with that, 67.25 East being squeezed between the Intelsats at 66.0 and 68.5 East!
So far, I know only that Amos 4 should have transponders in the entire low band, and in 12500...12750 MHz.
Anyone knows in more detail?
 
I can see some peaks here...Anybody can confirm?

The level of 11233H was increased, so both carriers are strong in my location, probably in Russian beam.

Amos 4 is still at IOT position!
And 11283H, 11408V and 11532H/V are still there, and look very strong here.
 
At least for Amos-4, there is a good explanation why it remained so long at the 67.25° East IOT position:
http://www.satnews.com/story.php?number=883423966

Latest TLE #95 of two days ago, suggests Amos-4 started to move West with just 0.2°/day.
But at epoch time, Amos-4 was still close to 67.25° East, so next TLE may show a faster drift.
 
This is still based on the old TLE #95, of 18 Dec!
It calculates a strange motion, making Amos-4 arrive at 28 Dec.
Like I mentioned, this TLE was created too close to 67.25 East.
Waiting for a fresh TLE, or a first signal...
 
Fresh TLE #96 has arrived, Amos-4 must be on 65.0 East since last night already! :)
 
AMOS-4 is finally active on its position 65°E. Two carriers are active last hour with weak signal in my location in Russia:

11372 V
11386 H
