Eddie, Stefan, LF,
=A0
The wind=A0has been in the NE=A0here too for a few days so I=A0was unable=
 to=A0launch my kite.
I need a southerly wind direction to in order to clear my neighbours' hous=
es.
It has been far too strong for balloons also.
=A0
I have made no significant changes here Stefan but I do seem to be getting=
 slightly more aerial current for no obvious reason.
I now have 0.24 A
=A0
As I may have mentioned: I plan to increase my aerial's height and length=
 by several metres in the next few weeks so hope to be putting out a bette=
r signal then.
=A0
I am still experimenting with matching transformers but have trouble in ob=
taining any=A0suitable ferrite cores.
If anyone could sell me an ETD59 type core I'd be much obliged.
=A0
I'll go VLF QRT in a few minutes as the noise according to Eddie's excelle=
nt grabber is now burying my signal.
=A0
I think that April may have been a record month for temperature here also;=
 I can't remember one quite so warm. There's a cold, fresh wind today thou=
gh.
=A0

Hello Eddie and Chris,

Eddie, i just checked your grabber to compare the diurnal noise levels in=
 UK and DL. Seems to be about the same, a minimum from 4....13 UTC, about.
Very good copy od Chris' signal! He must have improved things by at least=
 3 dB it seems to me. Maybe he can give some comments on this? :-)

Great about the VLF acty in UK and Canada. Still no chance for me to join=
 in, the wind comes from NE since several weeks now :-(. "The hottest Apri=
l since 1890", was written in the newspapers here...

73, Stefan/DK7FC
