Just want to make sure before I plug it in. For FSK, the manual states that pin #1 (FSK IN) in ACC jack has a pull-up resistor to 5V. So I assume the standard NPN interface from a COM port will work fine for that.
Pin #4(PTT IN) doesn't state it also has a 5V pull-up resistor. Does it so I can use the same NPN type setup? By the way, thanks for all the input I have received on setting up for RTTY with my K3 and DXbase. Based on several inputs I am using Hamscope which seems to interface well with the K3 and DXbase. AFSK is working fine with just two cables between the K3 (LINE-IN and LINE-OUT) and audio card on PC. Now I want to set up for FSK. 73, N2TK, Tony #311 _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
