I was definitely hearing noise on that frequency beyond what normal static would've been. It almost sounded like an ineffective jamming attempt, like what's normally audible below Radio Marti on 40m. I didn't check the rest of 31m for similar - too interested in the show! - but if it was everywhere, somebody else is maaaaaajorly throwing out junk. Now to figure out who the heck it is.
As for last week's issues being stinky conditions or the transmitter having a glitch, sounds like it was the former. Eric saying 'Last week, conditions were very bad on shortwave.' with no humor in his voice at all... things really must've been rotten everywhere. Repeating the digital transmissions was a wise idea, hm?
