Tested a Pulsat LX2000 a few years ago. The unit was retailed in Europe. It did not produce adequate gain for North American KU FSS reception. All I remember much about the specific testing results was that it struggled to receive all but the super strong transponders.
Several years ago we tested the Pulsat LX2000 and found that it only received the strongest transponders on the linear polarity FSS KU satellites. It was not 2 degree complaint with significant adjacent satellite interference. While it might work for the strong signals on the European satellites, it just didn't have the gain necessary for our lower power signals in North America.
