I think the more serious shortcoming of crystal sets these days is lack of selectivity, which wasn't an issue in the crystal set era when there were just a few stations within range. However, nowadays, with so many local radio stations - commercial and community broadcasters, the stations all come in on top of one another.
That wouldn't have been an issue during the war years as all former regional BBC stations broadcast the same programs simultaneously albeit on different frequencies. That prevented enemy 'planes from using the individual transmitters for direction finding.
The more I think about clandestine crystal sets, the less convinced I am that they were a mainstay of radio news gathering on the Channel Isles during the occupation years. As I said earlier, the late 30s was the high watermark for home constructed radios and hence, components to make small valve receivers would I think have been plentiful. Hence, why fiddle about with crystal sets?
