[QUOTE="Vipersan, post: 888897, member: 325666"] Still hoping to push for a fraction more from the offset ESX .. Variation depending on modulation type can be as little as 0.8db ..to 1.7db .. Typical example is the Startimes mux 5West 5154R 28485-5/6 8PSK Lockable on the prime ESX (focus) at 10.5db ...but remains unlocked when switched to the offset ESX which only gives 8.8db.. Possibly due to lack of a full sized concentric choke/feed ....more likely the inefficient arrival of signal at the lnbs throat (out of phase slightly and therefore more error prone it being 8psk.. I _will_ max this out given time ..but it can _never_ substitute for being at the sweet spot. At the risk of repeating myself ...in the words of Highlander 'there can be only one' rgds VS [/QUOTE]
