I've got a (mechanically) stable link to the institute now and actually transferred some data. The data rate is still low. Some bearing optimisations /fine adjustments of antenna will follow. But it works! Next step is the solar charger and then the Raspi, remote linked... Some imaginations which could be inspiring for some to leave the shack... https://www.dropbox.com/sh/z37q97r0yrsd99n/AABCr0FRW8GLEAVh4lWZN4OXa?dl=0 (please don't make public in the web) 73, Stefan Am 04.09.2014 20:50, schrieb LZ: > Hi Stephan, > > >> ... >> Sorry, this is mostly OT but i know there are a few OMs interested in >> remote sites for VLF/LF/MF bands >> > Off topic?
