seatel coastal 24 sat not locking

[rajus28]

hi,we tried to track satellite ST1 at 88deg E in india on seatel coastal 24 antenna on a vessel.on BDE we inputed following parameters
Name :-ST1--- ,....Position :-088.0E ,....Freq :- 0000 ,....ALT Freq :- 0000 ,....Baud :- 00000 ( symbol rate is 43978) ,...FEC :- AUTO (as FEC is 3/5) ,....NID :- 0000 ,.....POL TRIM :- +08 , we locked the satellite signal in decoder for 4 hours with good signal strength & signal Quality.After some time antenna was in UNWRAP mode searching for satellite .it used to get signal on decoder but does't lock .it keep on searching for satellite at Elevation 65 deg.
kindly rectify if my parameters are wrong or is their any other problem.

Without inputting a frequency of a live transponder on this satellite you never will get it to lock. The other aspect of this is Is the diameter of the dish big enough for the footprint of your chosen satellite?

Does this guide help you?

his is regarding system installed on vessel in India.Antenna was installed in China Model seatel coastal 24 here we tried to align the antenna to ST1 satellite at 88 deg E.For the current position of ship azimuth is 136 deg & Elevation is 65 deg for satellite ST1 service is Videocon D2H frequency are 11483 V,11546 V,11609 V,11609 H,11672 V, 11672 H. Symbol Rate is 43978 , FEC is 3/5 DVS 8PSK. we had feed following parameters in BDE
Threshold :- 161
Name :- ST1
Position :- 088.0E
Freq :- 0000
ALT Freq :- 0000
Baud :- 00000
FEC :- Auto
Network ID :- 0000 .
we tracked the satellite & recieved good Signal Strength & Signal Quality in Decoder elevation at 65 deg .AGC was 1984 & some times we get NID EE00 .Satellite was locked for 4 hours and signal disappeared . Antenna was in UNWRAP position and trying to track the satellite .tracking LED comes to ON postion but satellite is not Locked it keeps on searching in between signal is displayed in decoder and goes OFF.satellite does't locks.
pls let me know if parameters are wrong or is their any other problem.
As stated in operating manual frequency in MHz should be TP 11609 - LO 9750 =1859 MHz.Baud Rate (symbol rate) should be between 5000 to 30000 but the symbol rate is 43978. FEC is 3/5 for this satellite its not in given list so should be in Auto .Network ID or NID is to be inputed manually or recieved if satellite is tracked . on website i found Vpid of TP 11546 V is 5541 , 11672 V is 4441 should convert to HEX.
kindly assist me to track the satelite so that it remains locked.

Threshold :- 161
Name :- ST1
Position :- 088.0E
Freq :- 0000
ALT Freq :- 0000
Baud :- 00000
FEC :- Auto
Network ID :- 0000 .

Firstly repeating effectively the same post and ignoring the questions I posed isn't going to get you very far. I do not know as I have never owned one how to achieve your goal I am merely pointing out that in the information you have posted I doubt you will receive anything without frequency details as shown in red, have you tried contacting the company? Lastly what service are you trying to receive?

we have inputed following parameters in BDE
NAME :-ST1
POSITION :-088.0E
FREQ :-TP 11483 - LO 9750 =1733 MHz
ALT FREQ :- 0000
BAUD :- 43978
FEC :- AUTO
NID :- 0000
POL TRIM :- +0.0
AUTO THRESHOLD - 161 FOR COASTAL 24
feeding all above parameter we receive signal in decoder. but signal doesn't lock for this satellite . Antenna keeps on rotating (signal comes and goes OFF).

Firstly 88E is ST2 not ST1

ST1 is there but has no active transponders -http://www.lyngsat.com/st1.html
ST2 as you say is correct but that frequency is for a DVBS2 transmission in HD, does the Seatel unit understand S2 signals
Have you tried a different S1 frequency on the Ku band beam 2?
I notice that the S1 transmissions from beam2 also use unusual FEC and SR settings which may be your problem
Try setting FEC to 3/5 which is what it actually is rather than auto, as the unusual 3/5 setting may just be the problem
