I am having difficulty tuning 11.495 V SR 44100 on my Spiderbox 9000 HD combo from Intelsat at 27.5 degrees west. This transponder carries BBC and ITV channels. Whilst BISS keys are available and the signal is very strong, the transponder will not scan and the channels load. I have the same problem if I use my Technomate 5302 HD. So does anyone have any idea why this transponder is not tunable and can anyone recommend a patch that might cure the problem.
