Indeed, Ken, I remember seeing things like the Northern Radio discussed on
the glowbug list back in the 90's when it was on theporch.com. Do a 
google search
using quotes around "northern radio" and no quotes around FSK it will 
get several hits.

With my own eyes I have seen a couple versions of Super Pro with Northern Radio
tags on them. So at least some company with that same name was 
producing RTTY gear.
I have also seen assorted couplers and other things by them over the years.
