Hi - I'm trying to figure out what happens with WK2 and Win-Test. The only WK2 I have under hand is embeded in a MK2R+ SO2R interface from microHam and this interface is probably so magic that I cannot repeat the problem with! Does someone face the "spacing problem" with something else than the standalone WK2 chip or WKUSB? 73, -- Olivier / f5mzn
