[QUOTE="Vipersan, post: 853809, member: 325666"] ..Am I making any progress ?? Certainly doesn't feel like it atm. If there are any modulated signals in KA Low band receiveable at my QTH ...they may be out of my reach due to the lack of linear polarity access with the SL3 .. But I press on.. Got sick of the added complication of having 3 active LNBs at the focus so centred one of the KA band feeds as close to focus as possible ..and blanked off the other 2 . Leaving the active hole which is controlled by switching OFF the constant 22kz tone ..ans popping in line the hardwired up convertor . So KA band low is theoretically shifted into useable spectrum.. Probing the arc I found this definate spike around 30 East (approx) ..so not sure of its origin though strangley I suspect its actually from Astra at 28.2 ? Point is ..its circular ? RHCP ..as indicated on the captured graph Shows up with crazyscan set to Horizontal ..which in USA parlance (reverse of ours) ..is not LHCP ..but RHCP and only really present in H not V ...R not L ???? Ignore Any sat info on the crazyscan capture .. It's not relevant.. [/QUOTE]
