<div><br></div><div>The problem seems to be that if Win-Test sees no PTT line defined, it will never output <i>any</i> audio from the Internal DVK.</div><div><br></div><div>Perhaps if you define a "dummy" PTT signal on a disconnected serial port, that will make the Win-Test DVK happy, and custom software commands (via LUA script) can do the actual PTT ON/OFF. Ctrl-T in a script doesn't work so well because it always displays a "tune" pop-up window with a big STOP button, which is undesirable. It does close the Winkey PTT line though.</div>

</blockquote></div><br><div>The WinKey was designed for CW only, not SSB. It keeps the PTT timing internal, so that the PTT always closes before the CW signal is output. That PTT timing will not work for SSB.</div><div>
<br></div><div>My suggestion would be to abandon the Winkey completely for PTT, and just use a single LPT port or a single Serial port for both CW and PTT, using the Win-Test CW timing. For paddles, use the internal keyer of your radio if it supports both paddle and straight key inputs, or an external CW keyer wired in parallel if it does not.</div>
<div><br></div><div>FYI, at K3LR there are no Winkeys or external DVKs or CW keyers. Real COM ports or parallel ports are used for all software-generated CW and PTT functions, and PC sound cards for voice keying. Internal radio keyers are used for sending with the paddles. This is a simple, extremely reliable solution that works very well. Unlike N1MM Software, Win-Test rarely has problems sending well-timed CW via real serial or parallel ports, so you really don't need a Winkey at all.</div>
