Hi Andreas, I've got the same pairing Micro PA50+ and X6100. I've only played with it on bands that my antenna has resonance, but I think your SWR issue would be solved by useing an ATU after the amplifier. The internal ATU in the Xiegu is presenting a match to the radio, only, the amplifier is still seeing an un-matched antenna. Performance wise, with the little testing I've done, the pair seem to work quite well although I have had reports of a small amount of RF on my transmit audio (nothing nasty, but it is audible). Not sure if it is a patch lead issue, a proximity issue or I need to insert a choke between the two ..... need to play with it a bit more. Cheers Adrian 2E0MXK
