Although I respect the comments from the experts (and Lance and I worked on two-meters thirty years ago) I must say that I use a Signallink on HF RTTY running a K3 and a venerable Drake L-4B without issue.
If I was still on EME then of course I would have the full sequenced keying hardware. The Signallink is exactly what is described below, and I realize that I can, and have used the K3, with the built-in soundcard on my laptop but I have other uses for that card. Furthermore, I acquired the Signalink when I was using my prior transceiver so it's on hand. So despite its alleged failings, the Signalink has some usefulness in some applications.

If I had a dime for every EMEe'r who was had troubles created by trying to use a Signalink, I would be sending this email from the beach in the Carib! I NEVER recommend them to anyone who is serious about running any kind of power on digital modes because of the cheap and dirty way they try to claim that they have PTT control, when all they really have is VOX. What I was talking about, and what most EME'ers and serious VHF'ers require, is an ADVANCE PTT command (which is very thoughtfully provided by WSJT programs) so that everything can be switched and settled into place BEFORE any signals are generated by the transmitter. If all you do is HF QRP, then the Signalink is probably all you will ever need. If you ever go QRO, it will pay you to do it right the first time and get a fully capable interface!
