    Does anyone know what the hell could be causing this....

    103c
    0 90 0 88 0 85 0 88 0 82 0 93 0 84

    Sometimes, some of the numbers above drop to 0 then come back.
    I'm running 5LNB Slimline (non SWM) to a Spaun 16 port Multiswitch.

    Could this be AZ/EL/TILT, LNB, Switch or maybe a bad cable ???
    This is bugging the hell outta me... I can't find the problem and I don't
    want to rip everything apart.

    Thanks!

    it could be any of the above.
    have you ruled out your switch or lnb yet by bypassing the switch and hooking it up with a barrel connector?

    Sounds like one of the cables from the LNB to the switch or the switch itself. Are these signal numbers on all receivers? Try bypassing the switch with each of the 4 wires from the LNB to 1 receiver and see what you get. BTW what is a Spaun multiswitch?

    Spaun is a brand, very expensive......

    I've had a similar dropoff with a bad coax cable and/or connector. What type of coax are you using and what are your distances from dish to splitter to receivers. Also, if you had a power booster, maybe the power's gone bad... Just some ideas. :)

    Belden 1694a w/Canare, and aprox 30' to switch.

    I bypassed the switch and hooked up 2 HR22's (all 4 LNB outputs)
    One of the tuners had all 0's.

    So, thats still either the cable/connector or LNB.
    I'll probable disconnect the LNB, terminate the cable and check resistance for
    bad cable or connector. If everything is good, I'll replace the LNB.

    Could signal like that also indicate bad allignment ??

    You get decent signals on some transponders (particularly the 103c evens) so it's unlikely to be an alignment problem.

    looks like you have 1 bad cable run coming from the dish then.

    Could 1 of the LNB outputs be bad, or is that very unlikely?

    take the bad cable off that isn getting sat signal and hook up a known working cable to that output just to verify that it is indeed a cable/connector
