Firstly I would like to say that we do not condone piracy of pay TV systems.
Whilst I appreciate English is not your primary language unfortunately your post does not make much sense. You appear to be receiving C band signals on a Starsat SR-10C and there is intermittent clearing of the Geo TV. This is probably because the signal is encrypted in conax which is being altered (rotated) every so often to avoid piracy and the existing key in your system occasionally matches the key required. I therefore am unable to understand why 'any other receiver' would be able to decode Geo TV without these keys, but as you do not say more about 'any other receiver' I cannot comment further.
As you mentioned you already have another receiver, why not use the loop through facility from one receiver (assuming it has one) to feed the other stb then feed the cleared signals from each receiver to your TV, purely for educational purposes of course :-righton
