<div dir="ltr">Hi Carmelo,<div><br></div><div>FYI, your message appeared twice. Why do you want to do PTT via software commands?</div><div><br></div><div>Win-Test relies exclusively on MMTTY to handle all PTT functions. It can do this via COM port pins that MMTTY controls. You may not need to use EXTFSK. You can also consider using AFSK and VOX.</div>
<div><br></div><div>Though it's possible to create script that issues a software PTT command to a radio, it may not have the proper timing when using RTTY mode. But you can try the technique suggested at the bottom of <a href="http://lists.f5mzn.org/pipermail/support/2010-June/079662.html">this post</a> (which was for CW). You need to write two LUA scripts, a PTTON.wts and a PTTOFF.wts, specifically for your radio model. Then try putting #PTTON and #PTTOFF at the beginning and end of every RTTY message.</div>
<div><br></div><div>But it may not work right. Please experiment and let us know.</div><div class="gmail_extra"><br clear="all"><div>73,<div>Bob, N6TV</div></div><br><div class="gmail_quote">On Wed, Sep 18, 2013 at 9:41 AM, IT9AUG Carmelo <span dir="ltr"><<a href="mailto:it9aug@gmail.com" target="_blank">it9aug@gmail.com</a>></span> wrote:<br>
