Seems you are having a good start into VLF now. I hope i can see you here one day. My loop is already showing in your direction... With your long wire antenna you should be able to produce 100 uW without much trouble. Try SpecLab and a GPS module for the transmissions. It works very well. Each transmision comes from SpecLab here... 73, Stefan Am 08.05.2017 15:52, schrieb jcraig@mun.ca: > Hi Paul, Markus, Group, > > The level of expertise on this group is humbling and these results are > amazing.
