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..... LF: members.aon.at/grabber VLF: members.aon.at/grabber/VLF 73 OE3GHB Gerhard
