Hi Art,
If you are still going to use a K3/0 or K3, then you should leave it as mode 14. If you will only use it via software
control, the you can use mode 4 instead.
Another idea for you would be to buy the RRC Micro PC Client. This emulates the RRC and uses its I/O settings,
so if you have a K3 setup with cabling for mode 14 on the radio side, connecting via software will turn the K3 on
without any further interface. It of course supports various software clients for CAT control and also CW paddle
support on the newer dongles. This would be a great solution to be flexible in either situation.
