[Elecraft] K3S fsk with usb

[Don Wilhelm]

Peter,

You will have to gain access to the RS-232 DTR or RTS signals.
If you do not have the P3, you can insert the RJ45 to serial port dongle 
and pick the signals from that connector.  Although I have not tried it, 
I believe it will work.
You will also need to use a "one transistor keying interface" (google 
for it) to convert the signal level to TTL for driving the ACC connector 
FSK pin.

If you do have the P3, you can add a "Y" cable to the P3 connector 
labeled "PC" to gain access to the serial port signals.

Actually, you will likely find it easier to use AFSK A and drive the 
audio from the internal soundcard in the K3S.

73,
