Sorry about that. Maybe it calms down in a few minutes :-) (Dreamer, you know).

I have had the same problems, especially when rain came up while i was sleeping and transmitting over night.

Just been in phone contact with Markus/VU/DF6NM. Today is the last
chance to leave a trace on south India. We will try an early test.
Markus will start to receive at _*17 UTC*_ until his netbook accu is
down, which means about 90 minutes. So give it a try! QRG 136.172+-
