I wrote a small script (just my level of skills, while loops and so on ;-) ) that allows tto switch from the north-south loop over to the east-west loop to a certain time and then back to another time. The script is now tested the first time, i switched to EW since 14 UTC and will be back on NS at 16 UTC. You can see the difference at http://www.iup.uni-heidelberg.de/schaefer_vlf/DK7FC_VLF_Grabber2.html So, Markus, if you want to try a short EbNaut transmission soon in the morning, just tell me the day before, then i can switch the antenna to you just during the start of your transmission, while i'm still sleeping. And then back into Uwes direction, who prefers unannounced transmissions :-) I als removed the grounding on the relay pin of the unused antenna, which caused a coupling between the loops. Now it all should work well... It opens new playing fields, e.g. testing an alternative E field antenna on the second input. That will be a better choice for the 970 Hz experiments... 73, Stefan
