Fox/Hound needs to probably go away, it doesn't help.
"Hound" needs to be a toggle on the main display somewhere and not yank the frequency either. That would eliminate about 99 per cent of the awkwardness.
It has virtues in that the Fox has a queue to manage and that the logging is automatic. When the Hound sees the RR73, the Hound
knows they are logged. With regular FT8, this is not certain.
On the Hound side, it also dispenses, 100 per cent, with the trailing "73" which is also a benefit, especially when you consider the frequency shift, which also has technical advantages in terms of completing QSOs.
