Bob, the Prolific converters do not work well with W7. I have been using W7 with my K3 for over a year with a PCIe card RS-232 port. It worked the first time with no problems. Elecraf has quit selling the Prolific converter, but the one they were selling two years ago was Prolific. I think that some are having good results from the FTDI chip set converters which Elecraft is shipping now. You will need the latest drivers which are available from the FTDI web site. Surely Prolific will eventually get their act together and publish a driver which will work with W7, maybe they have by now. Willis 'Cookie' Cooke K5EWJ
