Hi,
I've just started working on a ship and we have a Seatel satelite for receiving TV signals. It hasn't been used onboard for about 3 years but I'm taking on the project of trying to get it back working. I know very little about satellites specifically but have dug up the following information.
Seatel 4894
48" dish with stabilised pedestal assembly
Controlled by TAC-92 ACU
I believe it has a universal twin LNB with the following spec
Output: Dual output
RF Frequencies: 10.7 – 12.75 GHz
LO Frequency: 9.75/10.60 GHz
Noise Figure: 0.2/0.3 dB
Polarization modes: Linear: Vertical and Horizontal
Polarization control: 13/18v switch
We have a number of decoders/receivers onboard in a cupboard from when it was working and the ship has been in different regions.
My first aim is to try and ascertain whether the satelite and PCU/ACU are working. When I power it up there is movement in the dome but the dish seems to rotate until a limit and then keep trying to move. You can see motor slipping and jumping back on itself. I don't mean Az or El here I mean a rotation of the dish itself.
Here's the complete newbie bit as I am unsure as to why the dish would actually be rotating like this? Whats it trying to do?
I have a DSTV decoder attached up and was trying to point at 68.5 E. Whilst I know the card will be out of date I assumed I could prove that the dish setup was working, then look into providers/packages and prices etc after that.
If someone could teach me about the dish rotation, advise how I might calibrate/reset it as it's clearly trying to move the dish beyond it's limits and offer any good suggestions as to where to start to simply confirm that the ACU/LNB and Dish are working, I can deal with which provider/channels afterwards.
Thanks in advance for any assistance.
