Yesterday I switched it on to prepare for GZ later this month and the adapter does not work. In fact, the only thing working is the tx/rx PTT on DTR. All CAT and CW (on RTS) are failing. I re-installed the drivers, and still no joy. Obviously some other activity, like anti-virus or Windows updates, have messed with the Prolific, which is not fixed by a re-install – probably because the ‘Repair’ install does not replace any existing files, even if they’re broken.<o:p></o:p></p><p class=MsoNormal>So I have bought a KeySpan by Tripp Lite (which I think is over-priced). I will report back!<o:p></o:p></p><p class=MsoNormal>73<o:p></o:p></p><p class=MsoNormal>Stewart<o:p></o:p></p><p class=MsoNormal>GM4AFF<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p></div></body></html>
