Hi VLF,I have added the remaining yoghurt cups of the stacked loading coil and put 100 of 100 iron power cores into them. The resonance was now found at 6.5x kHz but i want to go to my old frequency, 6.47 kHz. I am already on the air! The antenna current is about 150 mA but i still have to optimise things a bit. I have extended my VLF2 grabber for the band, http://www.iup.uni-heidelberg.de/schaefer_vlf/DK7FC_VLF_Grabber2.html Also i have added a 47 uHz window to give IW4DXW and others a chance to leave a trace there on 8.27 kHz. Maybe i will transmit some EbNaut later, but a simple carrier would be helpful for the first tests... 73, Stefan |
