My guess would be it was mostly inforced in german occupied countries probably mostly in cities where there was a large german presence. Would be pretty hard to enforce in places here they werent stationed permanantly to be around and see someone using sw. Maybe when they werepassing through they might check someone radio, if convenient. I would also expect most they did inspect where probably not converted so they probably destroyed the set, another reason we dont see many... Of course, just guessing
