Remove the beacon mode and the XG-3 becomes useless for T Hunts :-( Let anybody who wants to play with their XG-3 be responsible for what they do. Given what has been written in this thread, I don't see people rushing off, to build XG-3 amplifiers :-) We have all learnt something in this discussion, so let's build a bridge....... and get over it :-)
