LF: Origin of mystery staircase signal solved

[wolf_dl4yhf <dl4yhf@freenet.de>]

Greetings all,

Peter, DF3LP, has now finally found the origin of the mystery 
"staircase" signal on VLF, 12 to 15 kHz.
That signal had previously been pinpointed by Paul in Todmorden, and 
bearings verified by other means.

The Bockshorn-effect is remarkable.. and possibly a solution for all 
kinds of problems (limited garden space, unefficient antennas, ... )
Who will be the first radio amateur to build a reduced version of the 
phantastic OAM antenna ?
Peter has more photos on request, just in case you need more details.

Have a great sunday everyone,
  73,   Wolf .
