Hello group,

Short information from Stefan, DK7FC.

Unfortunately their was some rain and big clouds over his QT= H, but now it looks better include the actual weather forecast in the internet= . This causing some delays, but Stefan is now in the middle to bring up the antenna. He estimated a start time around 10am CET – so in about 30-4= 0min.

Dear VLF group,

Now, the wind forecast shows excellent wind for tomorrow and unstable and p= oor wind for sunday. So i will do the 11th experiment tomorrow, Saturday, 18= . June 2011.

Tnx in advance to Markus/DF6NM who will be available on the phone to ma= ke QSP to the LF reflector.
