First of all, this looks like an extremely helpful site and I appreciate your taking the time to read this post. We live in our custom 5th wheel most of the year due to work and we move about 3 times a year. Our last move has been to central IL and we just had a tech out for our latest install. We now have a 18" round dish and a 72.5 dish to get locals, they are routed through a Zinwell WB-68 6x8 multiswitch (they replaced my oval with the 18") we are using the HR22 receiver. I read the PDF on proper wiring of the WB-68 and that is not how it is hooked up. It shows the 18" on 18v and 13v and the 72.5 on Flexport 1, if I hook it up like this it gets no signal, if I hook up the "extra" from the 72.5 to the 18v, 22hz I get signal and can watch local channels. But no matter what I do after repeatedly running setup I can NOT get any signal on tuner 2. I have reset, hard booted and checked connections and I think the problem is in the Multiswitch. Can anyone here please advise? Thanks again!
