Hi all. I have a Topfield receiver with a 36" dish pointed at AMC4(I actually have 2 Topfield receivers hooked up). I've read that AMC4 has several other channels available besides 3ABN, but I've attempted several times to edit the SAT/TP edit menu. I've gone to this page, http://www.lyngsat.com/101west.html and put in the freq/pol and SR, but as soon as I do, my signal quality goes to zip. What am I doing wrong? If I put in one of the TP's I know I can get, it pops right up.
