I managed to bring up also the VLF Grabber again, by renewing the BF862 Transistor in the first stage of my VLF E-probe. The D-S channel showed a shortcut. Only this fist stage is located outside up on the roof in a shielded and waterproof box even with 2 diodes protecting the gate. Nevertheless I think it was damaged by lightning although recent thunderstorms and thus discharges were away a few kilometres from my QTH. The PA0RDT (Mini-Whip) is located at the same place without any diodes to protect the FET but did survive. So either the BF862 is a rather sensitive device compared to the J310 used in the MiniWhip or it was just bad luck. I'm sure the coming summer-season will tell.
