Guys, There are a lot of folks using the Signalink USB interface and fldigi now. The Signalink uses VOX to enable PTT (no CAT control), so in thinking about this as the receiving station, I frequently miss the first few characters of the senders' message. We could remedy this by using a method similar to the old analog modems RTS-CTS delay and sending a configurable increment of "idle" so that the VOX delay could be absorbed and the interface switched to TX mode before any data were passed to the modem. I would call this "VOX PTT Delay" and would like it to be configurable for up to 1000 msec. I get around this on my end by using the IDLE:nn macro call, but where I have to type in any text, this won't work. I don't know if the Signalink will detect "right-channel audio" for PTT, but even those of us that might use any type of antenna or switch-over relays could use such a feature to switch all circuits in before data starts being sent (before TXiD). I would think that a single configurable parameter would be sufficient for all modems as the interface would be common to the equipment configuration.
