I tried to help someone that has an HR-24 receiver and an old RCA receiver that is 10 or so years old. The HR-24 has a B-Band converter attached and the old RCA receiver doesnt. When the HR-24 coax cable is attached then the old RCA receiver only receives odd transponders. The dish is a slimline SL5 non-swm model. What could be causing this? I checked all connections and they are good.
