[ct-user] Problem Keying from LPT1 Using W1WEF Interface

[Gary Yantis]

My W1WEF interface works fine with 9.48 (and has with all the earlier
versions).  I'm not aware that the CT LPT1 keying has ever changed (at least
since 9.27).  I use both types of W1WEF interfaces as well as the N3JT
interface (it has a reed relay to isolate the higher keying line voltage of
older tube rigs) on both desktop computers and laptops 386s and Pentiums
with no problems.

Hi Ed...

>>I believe that the keying on the LPT ports changed after 9.34.  You may
want to check the archives on k1ea.com for this.  I know that the LPT
interfaces that I used for 9.27 will not work with later versions of CT.<<

Is there a W1WEF interface that is known to work with ver. 9.48?  For that
matter, is there a model that we know does not work with Ver. 9.48?  Do I
need to send the one I have back to W1WEF and ask for a specific upgrade.

Will a W1WEF Interface that operates properly with CT Ver. 9.47 also work
with DX4WIN?  I can download a demo and try that program, too.

Others responding to my question asked whether I've determined that the
transistor in the Interface is good, and what it means to key the IC-765
without putting it on the air.

No, I don't think I can prove at this point that the transistor is good.  i
know only that, with the interface connected, I get the same key down
condition I get when I hook up the com-2 interface (before hitting a
function key to break the key down when using com-2)

The IC-765 lets me turn off the VOX but still key the side tone.  From the
computer or a regular key or keyer's view, I'm keying; just not
transmitting.  This is a very convenient feature for testing and
practicing.

Thanks for the help!

Frank
