Congrats also Alberto and Vittorio for their excellent S/W and its success in this experiment. I am still plugging away at trying to find the cause of the cyclic variation of my antenna current on 72kHz Also tried a change in the antenna configuration. Mike, G3XDV, found that connecting the wires at the far end of his capacity top reduced the antenna current. My antenna has always had the ends of the capacity top connected at the far end so I tried disconnecting them. I also tried spacing them further apart to 2m. The result - it didn't make the slightest difference that I could measure! The new structure required two insulators instead of one. I normally use one of PA0SE's excellent ceramic insulators but two were a bit too heavy. I tried making insulators out of high pressure blue plastic water pipe and this seems to stand up to the high voltages quite well. Mind you, if they do start arcing across due to salt encrustation from the sea they will probably catch fire! Regards, Peter, G3LDO e-mail Web
