RichardI'd like to introduce my soul project, https://ssbtrainer.com
It throws the pileup a DX usually encounters at you, and the stations will try all sorts of tricks to get your attention - from cranking up their amp to chasing you around the waterfall.
It does real-time RIT, it lets you send partials (and call by numbers). If you ever missed the lovely sound of an OTH or someone whistling ola ola over your QSO - I have you covered.
