Hi Paul,

Good question. Maybe some kind of winter sleep?

OK, just try if you can use the todays transmission. But it is uncertain if just the end is missed or the beginning or some symbols inbetween.
Oh, you are thinking about kites. And i tried to install vlfrx-tools on
my Raspi today!
And i was looking for hotels in Strasbourg together with my YL, for the
next weekend. She will stay in a museum while i'm installing my ULF loop
in JN38OO to do a 2.97 kHz experiment at 150 mA antenna current.
And a few minutes ago i tested (again) my new coil for 8270 Hz. I am now
down to 8320 Hz, so i still need some more turns on the coil, which i
will add NOW.
I already saw that the system generates just up to 410 mA antenna
current with this power supply (25V/5A). So i need a stronger supply, 10
A or so.
Regarding EbNaut on LF, my RX is running all the time, so don't hesitate
to do some tests. However there are more challenging distances :-)

73, Stefan

Not too bad, got most of the day.  I'll still be
able to use it.

The mailing list is quiet this weekend, has everyone
gone away?  Nobody but us running experiments? I'm
thinking of having a little play again on LF.  Got as
far as warming up the GPSDO and getting a multiplier
working.  There's a kite here and 250m of nice light
strong antenna wire...
