Re: VLF: IW4DXW 8270.003 Hz

Thanks for report, Paul!

This morning, with the second transmission, I almost hit the "noise hole". Instead, the last one was 80% sent when the rain forced me to shut down the TX: too much kV for a wet and pretty small inverted "L" (12 m high, 36 m long) :-)

I'm looking for a new antenna, inspired by Stefan: near my house, there are two guard rails spaced about 700 m which are of interest for a ground loop experiment.

Stay tuned, as they say :-)

No decode, correlation Eb/N0 = -5.8 dB;

Decoded, Eb/N0 = -0.3 dB, S/N  -62.61 dB in 2.5kHz;

No decode on this one.
