    Adjusted the SNR for poor channel picture

    I have one popular channel that the wife likes watched and the SNR is only about 32%. Picture is very poor and sometimes does not show. Most of the other changes on the same transponder are about 52% on the SNR and show OK. How can I find tune this channel or do I need to tweak the LNB to improve the signal. I have a 1M dish with 0.1 TM LNB.

    might your dish have moved in the storms or are you at the edge of a sat beam?

    If you are in UK and watching 28.2E then that reading is really really low - you need to adjust dish and then LNB skew.
    Gigablue Quad 4K & UE 4K
    .........FBC Tuners:
    ------------------> GT-Sat unicable LNB to 1.5M dish(28.2E)
    ------------------> Gigablue unicable LNB to 80 cm dish(19.2E)
    .......................> FBC & DVB-S2X into 90cm dish (27.5W) Opticum robust Unicable LNB
    AX HD61, Edision Osmio 4K+, Zgemma H9Combo, Octagon SF8008 , gbtrio4k, h9se using unicable ports
    Zgemma H9 C/S into Giga4K

    It's an motorised system. My installer informed me to fine tune the motor and move it from the box. Now I need to work out how to do that. Do you have any instructions on how to do this with xtrend

    First select the channel you wish to view and go to it... then.... Go into setup> service searching> positioner set up. press the red button ( Tune ) OK then go down to Fine Tune and press the coloured button for the direction you think you need to go to improve the signal...you can go backwards and forwards a step at a time until you have got the best possible signal...then go down to store position and press the green button....remember to give it a few seconds between each press as there is a short delay in response time..
    Hope this helps....
