[ICOM] 756Pro & PSK interface

[k0bx at qsl.net]

Hi Ken, I am not sure Buck's add is clear?

I have several of them for rtty but they will only
receive CW.

To send CW I had to make up a cable with a 2N2222 to
key the rig.

I noticed that Buck sells a premade cable for CW
Keying:

LEt me know what you find out.
