The blindscan plugin is really an interface for the binary file that makes the tuner blindscan. The blindscan plugin is open source, and the binary file is closed source.

Apparently, Vu+ does not make a provision for c band, so the blindscan plugin was modified to make it work by adding this routine:
def correctBugsCausedByDriver(self, tplist) :
if self.is_c_band_scan : # for some reason a c-band scan (with a Vu+) returns the transponder frequencies in Ku band format so they have to be converted back to c-band numbers before the subsequent service search
x = 0
for transponders in tplist :
if tplist[x].frequency > (4200*1000) :
tplist[x].frequency = (5150*1000) - (tplist[x].frequency - (9750*1000))
x += 1

x = 0
We may be able to add another routine like that for the 10750 lnb l.o. We would need to tell the plugin to add 150MHz to each found transponder if a 10750 lnb is being used. This sounds easy, and it probably is easy for a Python coder to add this... But it is not easy for me to do.
