I'll have to check mine but for the past several years I've never 
encountered a spur at any frequency of interest.  For many years I used 
several different high dollar selective level receivers for LF 
reception.  I've found the R-75 to be as good as any SLM while receiving 
at 50, 60, 137, 185khz and up.
