Hello group!

Both of my grabbers for LF and VLF are working normally again since
yesterday evening. After a distant thunderstorm last week, the VLF
grabber failed because of a damaged FET in the first stage of the
E-Probe.

I replaced the transistor and added three protecting diodes into the
first stage. I hope this will solve the problem definitely.

The LF-grabber which was not affected got stuck last Friday evening when
the PC which is running all the instances of SpecLab hang. This also
happened because of a local thunderstorm. So you see, on LF and VLF
there are many other challenges beside propagation and noise.....
