[ICOM] 756Pro & PSK interface

[k0bx at qsl.net]

Well Ken, I don't think you are looking in the right
place?  CW is keyed from DTR Pin #4.  Pin #7 RTS in
some programs are keyed as well.

Take a look at:
http://www.aa5au.com/rttyinterface.html

It will show you the proper pin for CW, PTT and FSK
keying from the RS-232 port.

I don't know what type drawing Buck supplies, but if
you look at:
http://www.qsl.net/k0bx/soundcard.htm

You will see the one for the Kenwood.

#4 and #7 are tied together for PTT.  You could break
the connection and use #7 for ptt and #4 for CW.  RTTY
(FSK) does not use DTR but #3 TXD.

I hope one of those diagrams will help you.

I am using MMTTY for rtty as a plugin to Writelog for
RTTY.  I am also using Writelog for CW snd/rcv.
