I have an Ultraplua 900HD with the latest firmware (1.90.20) installed.
I also have a 4 input - 4 output multiswitch which is connected thus:
- Port 1 = D1 V (22k off)
- Port 2 = D1 H (22k off)
- Port 3 = D2 V (22k on)
- Port 4 = IS5 H (22k on)
Which currently feeds two decoders with the other two outputs terminated with a 75ohm resistor terminator.
The problem arises that if I've been watching D1 for a while, and then switch to either IS5 or D2, it seems to take about 60 seconds for the picture to come up. Looking at the signal bar on the info panel, it would suggest the decoder is trying to work out the signal level, or waiting for it to 'settle'.
Is this usual? If not, what can I do to cure it? I'm concerned I might be causing some damage somewhere if left unchecked.
The other thing is, that I bought a dual LNB which allows simulataneous reception of both D1 V/H signals to all decoders connected to the multiswitch. This seems to work fine, however I noticed that some signals are much less in strength than when I had a single LNB on D1. I'm using a Hills 80cm dish atm.
Would a 0.3 noise figure dual LNB improve the signal quality level over a 0.6 noise figure dual LNB? If so, by how much roughly?
Any help would be much appreciated!
Baldrick.
