Thanks Don. I wasn't quite sure if the KUSB supplied was just a stock USB-RS232 converter, or whether it may have been customised by Elecraft to leave the extra pins open circuit, so when I tested the interface I did use the "special" intervening cable.
Next step will be to set up the K2 with some logging/contest programs and find a nice CW contest to give the radio a bit of a workout :-) 73, Matt VK2RQ > On 9 Jun 2014, at 10:28 am, Don Wilhelm <[email protected]> wrote: > > Do *NOT* plug the KUSB directly into the K2 AUX I/O connector.
