Hi Jan,

Thanks for the email, most interesting! So i'm really looking forward to=20
such special condx! Do i understand you correctly, you have had a 2-way=20
QSO on 500 kHz with a PY station? Sounds as magic as 50 MHz or so.
Ah, when i read to the end to your mail it rather sounds as if you have=20
been working as the radio operator on a ship?
I have an idea: Tell it to me in a loooooooong MF CW QSO, rag chewing as=20
some say... :-)

Also thanks for the IARU link. What i find interesting is the comment=20
from TF2JB. I wonder if TF3HZ knows him? Maybe a good adress to ask for=20
common projects with Iceland below 1 MHz.

73, Stefan
