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...
