[QUOTE="Llew, post: 1136596, member: 175007"] A test of the viability of receiving the Turksat 4A 42E KA circular polarised transponders using my modded Inverto Saorsat LNBF. Currently, there's only three that I can receive, and of those, I can only lock one. The LOF of the LNB is 1 MHz adrift, so needs retuning. Otherwise it's remarkably stable considering the DRO puck is not even glued on properly (sticky tape). As the LNBF outputs a reversed spectrum similar to a C-Band LNB, it was necessary to choose the C-Band LNB option as a 'fake KA' in neumodvb. This gives the correct frequency order in the spectrum chart. Note - I'm not sure why, but the L polarities are shown as vertical (R). I can't remember if the polarity depends on which of the twin outputs you use.
