Recently got Directv (LOVE IT!) with a HD DVR for home, and a H21-100 for our RV, with a new SWM dish ( an SL3, with the 4 pigtails). I even bought a new HD Vizio 22" for the RV. But, now, it looks like I need a $$$$$ signal finder to get 99 & 103. I only have the cheapie yellow signal finder, and never had a problem getting 101. I attempted to understand the "dither" method, with no luck (actually seems to be a pretty archaic method!). Question: Since we travel often, and have to set up almost daily, what's the best way to get the HD satellites? Do I really need to get one of those $X00 signal finders? Is there some basic (cookbook) procedure for the novice traveler? (also mystified as to whether I MUST USE (or not) the BBC with the SL3? Thanks, gang, for any input.
