Hello Uwe and welcome on board!

Congratulations to your success. I wondered about the signal on my
grabber and asked Stefan if he is aware of any experiments going on down there. But like me he had no clue.

Luckily the riddle is solved now. Markus, Stefan, Ossi and I have
observed some VLF propagation effects recently and your activity will increase our knowledge (or guesswork) even more.

So just keep on transmitting as long as possible and do for your wife what Markus already proposed! By a pair of rubber gloves.

73 es tnx

OE3GHB
Gerhard
