The key is the same for two frequencies, the channel packages are the same on both frequencies. The composition of the channels changed earlier, were open and encoded several times.So... the keys are the same for 12073H and for 12245V? The post you point is for 12245V...
And according with flysat the biss channels from 12073H are from june 2023... thes post with keys are from jan 2023...
I´m not sure if we are talking exactly about the same channels
