On my H20-600 all my Odd Transponders are 20 points lower then my Even Transponders. My HR20-700 is fine on both tuners on the even and the odd. I changed the BBC with the 3 extra I have and still not much different. I changed the connector in the house and still nothing. It was acting like I had a loose wire,If I wiggled it it came up.So I changed the connector and still the same outcome. Do you think my wire is going bad? Or has anyone else noticed the H20 being this way?I have the ox2024 software too.But only yesterday I have noticed this. It seem to be getting worse. I have some 60's on some of those Odd TP's.
