For those technical experts out there, can I replace the 105 LNB with a DP dual to pick up the 129 satellite? Or should I do the "Mad Scientist" hookup? I ask this because the Baltimore, MD locals on 105 will be moved to 110/119 (probably 110) shortly. My point dish screen indicates that I am receiving a strong signal for 129 (95 - 100). If I want to get HD, it would be pretty simple to swap out the LNBs rather than reinstall my old Dish 500. I don't know when the Balt. HD locals will be available or on which satellite, so I'd rather not point a dish at 61.5 yet. What do you guys think?
