Probably the most common l.o. frequency for a linear ku lnb that is used in North America will be 10750 MHz. This was covered in post #1 of this thread, but many get confused on how to make the 10750 lnb blindscan and give the correct frequency output. Here is a quote from the NimManager file.
elif currLnb.lof.value == "circular_lnb":
sec.setLNBLOFL(10750000)
sec.setLNBLOFH(10750000)
sec.setLNBThreshold(10750000)
The meaning of that code is simple: The circular lnb setting in antenna setup has a l.o. of 10750 MHz. I found this bit of code some time ago, and was able to get the 10750 lnb added to most blindscan plugins. Follow these two steps in order to use a 10750 l.o. lnb in blindscan. (1) Select the Circular setting for the lnb in antenna setup, and (2) Make sure you are scanning Horizontal and Vertical transponders in the blindscan plugin menu.

A couple of lines of code were added recently to the blindscan plugin that sets the default polarity to circular instead of Horizontal and Vertical when a Circular lnb type is used in antenna setup. Circular polarities have also been made the default in the blindscan plugin when a C Band lnb is used in antenna setup. Blindscanning with the wrong polarity type will cause problems with the blindscan data or output!
