Waveform and FFT plots.
Red, Green are H-Field horizontal ferrite rod antenna channels. Yellow is the H-Field vertical ferrite rod antenna channel. Magenta is the E-Field antenna channel.
Green Station #668 and #1494 are permanently offline. Due to a failure in #1494, the controller board was replaced. Ths CPU ID determines the station number, so there is a new station number: 1682. The antennas and enclosures were reused to build up station #1682.
