Cannot do this as the software sending CW would be straight CW being sent to the CW input jack. PSK-D and FSK-D from CW is only capable from the paddles input.
But it only takes a very simple interface using a transistor and resistor using the circuit described on the AA5AU website from a COM port to pins 1 and 5 on the ACCY connector. ------------------------- 73, Greg - AB7R Whidbey Island WA NA-065 On Mon Mar 23 13:16 , Brian Machesney sent: >Don, > >I am a "digital mode neophyte."
