Well, somehow i didn't want to stop, so i now built the RX too: https://dl.dropboxusercontent.com/u/19882028/LF/DK7FC_fiber%20optic%20active%20dipole_RX.jpg I made some changes in the RX schematic, using a J310 instead of the BF862 but the principle schematic is the same. The working points look as expected. BTW that electrical/optic/electrical converter must be quite wide in the transferred frequency range, i guess starting from a few 100 Hz to a few 100 kHz.
