<li style>OK</li></ol>But, this will probably make no difference if you are using a WinKey 2 chip, because the documentation says: "In WK2, PTT is always enabled and there is no reason to turn it off since it is a separate output now. The PTT enable bit is not used and is ignored by WK2."</div>

</blockquote><div><br></div><div style>It is not a bug. When Win-Test is configured to use a WinKey for CW, all CW PTT timing is delegated to the WinKey PTT output. Other PTT outputs are ignored. That's because only the WinKey knows when the CW is starting and stopping. So is up to the WinKey to decide when to close the PTT output, based on the timing defined in the "PTT Tail" settings in the WKSETUP dialog.</div>

The timing with Win-Test should be fine. </div>
<div style><br></div><div style>Which radios are you using? If you are using an Elecraft K3 or FlexRadio, the "CW/PTT keying circuit" is built right in to the radio.</div><div style><br></div><div style>Consider selling the WKUSB LITE since you don't need it at all with Win-Test. You could connect a paddle directly to each radio (two paddles, one per radio), and use the internal keyer of the radio for manual sending. This gives you more flexibility for SO2R too, since Win-Test doesn't immediately move the WinKey paddles to the second radio when you press "CapsLock" or "Shift," and Win-Test doesn't define independent CW speed per radio.</div>
<div style><br></div><div style>On the other hand, you may need to build a lockout circuit since Win-Test cannot prevent simultaneous transmission by both radios when you are using a paddle to each.<br></div><div style><br>
