This is a slightly different approach but I've been wondering about adding a linear amp to the QMX+ between the existing PA and the LPFs, where T501 is. I'm wondering about something such as the

Practice mode? (But I don't know about PA drain voltage in this mode in the moment. Go back to my work bench in some days.)

My QMX (V1) also exhibits the bug reported by others where it will occasionally look like it has exited from the menus back to the VFO screen but hasn't. On a couple of occasions, the menu item was
