Sky card de-activation

[junger]

sorry, forgot to mention that one of the affected boxes recives the vault on a single feed installation

You cannot run more than one box off a single feed from an LNB, a twin LNB will run two receivers, a quad four and a quattro fed into a multiswitch, as many as the switch has outputs.

Thanks Rolf
The installation has worked for the past 2 years and is as follows.

I dish
2 lnbs
LNB' s seperately amplified (due to the long rg58 cable run)
2 feeds Into a phillips unit labeled as Vertical & Horizontal (with seperate gain controls)
6 feeds out of the phillips unit to 6 sat boxes.
each sat box has a 2meg rf separation.

Does that ring any bells?

sorry-should have said 2 rf channel separation (ie 24, 26, 28) etc:

 

[rolfw]

Yes, it can't work properly, as there are more than two states to the LNB, as well as vertical and Horizontal, there is low and high band, and the LNB cannot feed both at the same time, so if you want to watch a channel in low band (below 11700), and one in high band, the LNB will switch to high band and you won't receive the low band channel.

cheers Rolf
That makes sense, so I turn all receivers off whilst i do the test on one box, is that right

 

[rolfw]

Yes, if they are non Sky digiboxes, if they are digiboxes, they default to high band vertical when in standby, so you need to either disconnect or power off at mains.

They are all sky digiboxes, does the same theory apply?

 

[rolfw]

Try it and see.

Thanks Rolf
ok. I'll let you know when i,ve tested it

 

[junger]

Found the problem. It was as you said, it was not a universal lnb but 2 output fixed h & v highband. fitted lowband and got 3 free music channels but lost the lisings and sky news which i assume to be highband.
thanks for all your help
