Mr Grahn of https://www.grahn-spezialantennen.de/ had to stop working for a couple of months (medical reasons) but now he is back and I was able to get one of his highly sensitive Very Low Frequency modules to fit on my Grahn GS5-SE antenna tuner. As before, the delicate device ("treat like glassware, do not throw") was extremely well packed for its safe and intact arrival.
