We haven't had QSO before but i am looking forward with interest to your LF activity and hope to be QRV as well. I am using a 100m or 300m vertical antenna and i am QRV in regularly CW. You will hear my signal! :-)

Hi Mal
Thank you for the response. So I will take my attenuator box to the site, connect the mast to the RX and see what happens. It will be difficult to get a receiving antenna far away enough, and I hope we will not get to much QRM from the line running up the mast for the lights, or from something else. But I will have a lot of help there. Ham engineers and operators. May be some of them will get the LF virus and  get in my footsteps. Soon I'll be back with more news about this event and I'm looking forward with pleasure for our next CW QSO. Digital modes are not on the plan - maybe QRSS3 if there is a need for.

BTW. For those who speak German: I will report about the event on my Blog: www.funkperlen.wordpress.com
