[ICOM] 756Pro & PSK interface

[Ken]

You are correct Joe, Buck does sell a cable for CW keying.  BUT this cable
will still have to key from Pin #3 because Pin #4 is tied to pin #7.  The
CwType program wishes to key from pin #4, and the GLK kit keys from pin #3.
It really seems that unless there is a command to change the key from pin #4
to pin #3 this GLK version of his kit will have a hard time working.

Thanks Joe for the response.  Did you use the GLK kit or the original RASCAL
kit where you added the transistor?  and did you use pin #4 for the CwType
keying and pin #7 for the PTT?  OR did you use pin #3 for keying?  If so,
how did you get it to work?

What program are you using for RTTY?

Joe, you sound like you have the answers I'm looking for.   BTW, what
program did you use for sending CW?

Thanks for you help,

Ken H> K9FV
