Perhaps you were asking if these circuits or MFJ computer interface cables
are already offered for sale by someone, pre-made.  Well, this is not a
Win-Test question, but I did a quick Google search, and did not find any.
 Contact MFJ.

Alfredo,

See this link for a circuit you will have to build to connect our MFJ-432 to
your computer's LPT port.

The MFJ-434B already has a "Remote" connector that you can connect directly
to your LPT port.  This is described in the MFJ-434B manual.

In Win-Test, the LPT Properties dialog documents what signal is on each LPT
pin.  You must check the appropriate "DVK" boxes for each pin you connect to
your MFJ Voice Keyers.

If your computer has no parallel ports (no legacy LPT port), you will not be
able to control your MFJ boxes from Win-Test unless you install a parallel
port card or USB-to-LPT adapter (though many of these adapters are only
designed to support legacy printers, and they may not be compatible enough
to work with Win-Test for DVK purposes).

To use the Win-Test internal sound card DVK, connect your mic. to your PC
sound card and your PC headphone/speaker output to the mic. input of your
radio as shown here.

I need to know which are the interfaces that I need to connect my MFJ-434B &
MFJ-432 to the computer, to transmit with the F Key.

Here I see how to do it, but I’d like to know if it is for sale already
done.

As well how to do it among the sound card of the computer. Thanks
