Make a contact

Press the button. FT-0 handles the rest, which is nothing. Watch a complete six-step exchange unfold in real time, then find it already confirmed in your log.

Nothing, correctly

Every simulated QSO is a faithful reproduction of a real FT-0 contact: two stations exchange silence, a report of −∞ dB is implied, and both log the other before the exchange concludes. The simulator is, by design, indistinguishable from the mode itself. You may consider these contacts valid. The Working Group does.
