    I will be replacing my SL3-P LNB with a SWM single-wire LNB. I will be using one of the present four cables coming into the house from the SL3-P. What is the easiest way to determine which of the four cables I have hooked up to the new LNB? I thought I would just put a 75-ohm termination on that cable at the dish end, and measure each of the cables in the house for the 75-ohm resistance. Anyone know an easier way?

    Connect the SWM PI to one of the cables and use your tongue to feel the "tingling" sensation. !rolling

    Good idea, except I think I will use a DVM instead of my tongue. :)

    Disconnect all 4 from the dish first (before applying power), and be careful not to short any of them out as you test for voltage. Don't want to damage the PI by accidentally shorting it out.
