I was doing a translation of the operating instructions for a Panzer radio set, Ukw.E.c and 20W.S.c

I did a search on the term and came up with a couple entries showing hits for E52 receiver. Looking

at those texts seemed to prove, “Schwebungsluecke” means “beat note”, while “Schwebungsnull”

means “zero beat”. Good enough. ( For now. )
