Badr-8 is getting there it takes a bit longer with these electric drives,
So it will be a few more weeks to arrive at 26°east.

Transfer of transponders to Badr-8 in a few weeks time

 

[barney115]

so some coverage for Africa, Europe, and the Middle East
there may be some small hope to get a lock on this satellite then William-1 ??

 

[nadz123]

Are you able to see any tests from this bird in the UK yet?

 

[barney115]

Just some test channels new at 12563 V 27500
ONLY 9db Signal
170 channels found with Blind scan .
MTV Lebanon strongest TP at 12.5db signal .

Yes barney115 it looks very promising here is what I currently get with a 100cm dish from Badr-4,
S/R 27500 unless stated
======== SQ ===100cm dish + Edision Primo @ 26 east
11938 V = 66%
11958 H = 66%
11977 V = 77%
11996 H = 77%
12034 H no signal
12054 V = 69%
12073 H = 64%
12092 V = 52%
12111 H = 44%
12130 V = 56%
12149 H = 0- 55%
12169 V = 64%
12182 H 16200 =40%
12226 H = 56%
12245 V = 0-52%
12523 H = 64%
12523 V = 56%
12563 V =64%
12566 to 12635 feeds
12643 H = 64%
12683 V =59%

Badr-8 is supposed to be a lot more powerful so I will compare these results when it starts.

 

[william-1]

Badr-8 now 2 days to enter orbit @ 26° East

 

[oussforsat]

Now . Badr-6 moving 0.3E maybe most it's on its way out of service

 

[william-1]

Possible changover to Badr-8 tonight.
Badr-4 S/R 27500 unless stated
My set up for this test 100cm dish + TM 5400 M3
Sun 15th Oct 16:30 -17:30 GMT
11938 V = 10.5dB
11958 H = 10.7dB
11977 V = 11.5dB
11996 H = 12.5dB
12054 V = 12.2dB
12073 H = 9.4dB
12092 V = 9.4dB
12111 H = 9.8dB
12130 V = 9.2dB
12149 H = 10.9dB
12169 V = 9.4dB
12182 H 16200 =7.9 dB

12643 H = 11.2dB
12683 V =10.2dB

Error now corrected for 11538 V

 

[barney115]

HOW COME 11938 H = 10.5dB Was never before listed on Flysat ??
is this a NEW TP exclusive only for Badr-8 ??
or was this a typo ??

Listed on both flysat & lyngsat typo error by me

 

[barney115]

11958 H is listed
11938 H not listed for me can you provide a link William-1 just in case i not looking correctly ??

see links to lists in post #14 typo error by me

william only wrote down the wrong polarization

 

[william-1]

Now . Badr-6 moving 0.3E maybe most it's on its way out of service

No movement of this satellite on any tracking chart can you provide more info ?

 

[EnoSat]

0.3 degrees is not displacement, but inclination
