The nicture looks nice, nothing which is ugly ;-) Also the rod looks very suitable for /p. Have you used litz wire for the coil?

Actually it was QRSS-120. I'm doing that for some DX RX skeds :-) Tomorrow i will travel to France again (JN29OD) transmitting on LF, just as last year but hopefully with a stronger signal. Try to listen to it with the antenna inside the house. This could be realistic ;-) I will comare the TX antenna and the loop and the ferrite antenna on the RX side. Looking forward to that :-) 73, Stefan/DK7FC
