Re: LF: TXing on VLF again, A fan in series to the antenna?! :-)

[Paul Nicholson <vlf0403@abelian.org>]

This time, a good signal at about 0.35 fT

 http://abelian.org/vlf/tmp/160414a.gif

but the noise was high from the same direction so
cannot be avoided by steering the loops away.

I don't know if this is 150uW, from the signal
strength I might guess 50uW max, probably more
like 30uW.

I ran all 6300 seconds of the carrier through EbNaut to
decode an 'all-star' message at two settings:

 Code   Symbols    Chars   Eb/N0
 8K19A   15.0 sec    3     +0.5 dB
 16K25A   7.7 sec    3      0.0 dB

I couldn't get a 4 char message to decode.  If the
noise wasn't so high this signal would do very well.

How about a daytime test?
