[GreenKeys] OT: Hugo Gernsback's callsign?

[Dave Horsfall]

This is my last resort...  It's said that SF editor Hugo Gernsback had a 
callsign, but I cannot find it.  Anyone happen to know, one way or the 
other?  (I've been compiling a list of "Notable Amateurs" for quite some 
years, and he'd be a nice addition; preliminary version avalable at 
www.horsfall.org/lona)
