Have you swapped the the sequence: connect the wall outlet cable to the second card and then interconnect the first card to the second? I looks very much that: The second card does not get enough signal(as i said: The cable signal is typically so low that not more than one receiver can be conneted), very annoying. So you need an amplifier. Maybe an external splitter would be worth a test too, so both cards gets a lower level Maybe something like BVE 2-01 @ 2,90 Euro. An amplifier like Axing TVS 10-00 37.90 might be too fat. But don't by too cheap. The amplifier must be specified for "cable" else the signal quality may degrade. But a Axing TVS 8-01 16,90Euro TV distribution amplifier "suitable for CATV (TV, Radio)" would be sufficient too. (See reichelt.de for a datasheet) >> - Use the old card as second board >Check. That means: If you use the old card as second card the receiptiton on the second card(=now old card) is still broken?
