[QUOTE="Vipersan, post: 804389, member: 325666"] Its been a while since I took a look on 9East with my ka lnb .. You will remember I never managed a lock on Saorsat ..due to what I belived was a modulated blank carrier blocking any possible reception .. Well I still can't lock saorsat ..and that carrier no longer registers on the F15 as video capable ..but carrying a blank signal ..though modulated. The carrier is still there and prevents locking of Saorsat ..but I suspect its now carrying data ..coz the F15 doesn't know what to make of it anymore .. I'll investigate fully with the TBS card ..assuming there is sufficient signal for a lock .. I used to get 12 db with the ka lnb at the focus on Christina ...but also got 8.5db when used as an offset on Christina (offset by around 5 to 6 degrees) ...or 8.5 db on a 65cm offset solid dish with the ka at the focus. The ka along with a slim ku have been mounted either side of the Cband lnb on a couple of simple blackets I designed using bent ally strips and 22mm and 15mm pipe clamps as used by plumbers.. The whole lot fed through yet another switch (diseqc 4 port) mounted on Christina .. The only port I cannot use is port2 ..as this is the same port /output from the 16 way uncommited switch from the various receivers (via sps switches) in my system ... the diseqc 1- 4 port is connected to port2 of a diseqc 1.1 uncommited switch ...thus sending control info to switch to port2 (uncommited) would be misinterpreted by the 4 port switch between it ..and the lnbs ..thus selecting port 2 on this also ...by default.. So it is left blank ..and the lnbs are on ports 1 / 3 & 4...to avoid this conflict. It works well enough ...although signal levels on lnbs designed for offset dishes ..and offset themselves on a pf dish .. Well ...lets say ...I don't believe in ..nor expect miracles. Ohh ..and the ultimate in screening for the main feed from the switch ...as it now runs _inside_ the lower tripod leg .. rgds VS [/QUOTE]
