The ultimate, however, and what I thought might be happening before I actually listened to the video, would be two simultaneous QSOs with two different stations. Hard to get that all into one neural network.
A couple times in each contest while S&P I'll drop my call to one guy and get two guys coming back. When I copy them both and send my exchange, I get two QSO's in the time for one. (Assuming a no-serial number contest).
Admittedly copying two calls and exchanges simultaneously, is easy compared to sending two calls simultaneously :-).
