[Spooks] The Bureau and the Mole

[Daniel Piazza]

Nearly finished with Vise's Bureau and the Mole about Robert Hanssen and 
wondering . . . was there any evidence that Hanssen got instructions from 
numbers stations?  Vise only discusses dead drops and mail contacts.  He 
does casually mention that Hanssen was a ham from a young age, but there's 
no discussion of radio being involved in his espionage.

Sorry if this has been discussed before, but the archives are not easily 
searchable.
