Hi LF My progress to get access to LF: Added a coil on top of the 300mm pipe. With this in series can reach resonance at 270KHz https://dl.dropboxusercontent.com/u/7162072/Fotos%20varias/MF/IMG_20160
Hi Luis, Very nice! You could reduce the distance between the upper and lower coil so they get a better coupling. This should bring you down to 137 kHz. You could make the distance between the coils,
Hi Dave, Stefan, LF ! :-) Well, the big coil (double layer) is wound in the right sense, as CCW. Just as the other coils But unfortunately it is wound top to bottom, and the coils in the pipe are wou
Hi Luis, Turning the bucket will solve your problem. Its like a variometer where you can add or substract L by turning the coil. But don't collect to much water in the bucket ;-) 73 from the tree! I
Hi Stefan Unfortunately, even with bucket facing sky ..... rain will not be a problem here ! Hardly 95 litres per square meter collected since january 1st. And only thanks to rain during last week I

Hi Stefan Yet another convincing argument: As isolated coil, it can be covered with a bigger buck to get a step into VLF ;-) 73 de Luis EA5DOM De: [email protected] [mailto:owner-rsg

Hi Luis, My congratulations! Your first step on the 2200m band. It is very nice! During my active time on LF (2003...2004, 2009...today) i didn't see a Spanish station on the band. Once i can see you
Hi LF Thank you Stefan Unfortunately there is no other Tx activity on LF from EA. And have no info about this being done before Yes, I'm in IM98WN. But need to fix many things before getting more pow
