Re: VLF: EbNaut transmissions on lower frequencies?, pre-tests: 6.47kHz

[Paul Nicholson <vlf0403@abelian.org>]

4uHz, a good result for equipment and propagation.

We are struggling with the QRN.  A crazy time of year to be
doing this.  Most days are quiet only between 04:00 and 12:00,
just a few days recently offer a full 04:00 to 21:00.

We should perhaps try to use this daytime window.

Before suggesting further attempts I'd like to spend a bit
more time measuring your recent signals.  I'd like to work
out the chance of getting 20 chars across in 16 or 17 daylight
hours.

I haven't exhausted recordings of the 22nd and 25th, there's
still measurements to pull out and things to try.
