I'm currently using an old Houston Tracker satellite receiver to motorize my dish. My remote doesn't work well, and adding satellites and fine tuning for increasing signal strengths is challenging. I'm considering purchasing a 4dtv receiver. Would this type of receiver help me in pulling in stronger signals and be easier for fine tuning to pull in some difficult KU/band satellite signals, and programming and hunting for new satellites? If not a 4dtv receiver, what type of satellite receiver would you recommend?
