Thank you tempo, that's a bad mess-up on the RCSC site then!
Hope you'll figure out the complete frequency plan based on your observations.

Still do not know that the map of the satellite have been published,but if this is Kazsat 3's coverage map, then I explain why I don't see no trace of the satellite signal in my area with 1.50 m dish.

tempo thanks for posting screenshots ...
I can not follow the test Kazsat 3, because I am following those Eutelsat 3B.

10845 V-first test carrier found.Finally, after I posted the previous message, I was immediately refuted by reality after I've positioned well the antenna at 58 degrees(I have not yet stored 58° East into my positioner}.What I find amazing as the test signal is strong enough if you take into account the map posted above.

Well, I have 2 motorized dishes, so my second dish watch to Eutelsat 3B testing too

As I guessed yesterday, this morning they tests last 6 transponders in low subband 10700-10950 MHz.
Already tested TPs:
10720 V
10761 V
10803 V
10844 V

Right now 10886 V is active.
Seems few hours later all 28 TPs will be tested.

 

[satesco]

Indeed,@tempo,it is signal test at 10886 V.Luckily I get the signal as well.

 

[hvdh]

And also here in NL there is 10886 V !

Just for fun, I combined to two footprints from RCSC.kz.
The -3 dB contour is Steerable beam, the -4.5 dB contour is Fixed beam.

Edit: now carrier on 10929 V.

Tempo, only below 10950 MHz there are narrow (36 MHz) transponders, is that right?
Then roughly estimating the central frequencies, this could be the plan:
10721, 10762, 10804, 10845, 10887, 10928 H/V (12* 36 MHz)
10981, 11044, 11106, 11169 -/V (4* 54 MHz)
11231, 11294, 11356, 11419 H/V (8* 54 MHz)
12531, 12594, 12656, 12719 -/V (4* 54 MHz)
That would be total of 28 transponders (12* 36 + 16* 54 MHz), total bandwidth 1296 MHz.

RCSC site says: total of 28 transponders (18* 36 + 8* 54 MHz), total bandwidth 1080 MHz.

Too bad I didn't check earlier for the tests.
Maybe, there is actually just one footprint available since they fit so nicely on top of each other.

Yes, all TPs info you suggested above is right. Frequencies tolerance is ±1 MHz.

P.S. I think we needs in additional function in CrazyScan - to store spectrum info not only as picture, but also in some text format, to know precise frequency info in any moment. I will ask CrazyCat about this necessary function tonight in ICQ chat. Seems to me it's not a hard task to do. The only possible problem could be size of that text file.

 

[Marcus_21]

Reworked the frequency plan provisional, based on reports of tempo. Thank you all for reports.

Yesterday they tested again TPs in low subband 10700-10950 MHz, and right now they repeat test of 11200-11450 MHz subband. I already had carriers 11231V and 11293V last few hours.

The true frequency plan of Kazsat-3 has posted on cosmonautics-news forum

tempo thanks... I just updated my website
