In order to give
proof for above mentioned interference potential of PLC,
Austrian Radio Amateurs have recorded the following videos
and audiofiles. In contrary to the advertisements of PLC
companies the videos do show severe levels of harmful interference
to radio spectrum users. Measurements have shown that PLC
modems often do not comply with the intention of EMC limits for CE-marking
according to EN55022B or CISPR-22.
All videos have been made using a Sony
Mini-DV Camera and are shown with orginal soundtrack. A mobile
(Kenwood TS50 or Yaesu FT817 with 1,6m mobile whip on car)
and an average portable world radio receiver (AOR8200 with
short stick tuned for 27MHz) have been used.

All locations (PLC trials) have been selected by

Upper Austria (Linz) and
Lower Austria (Neunkirchen)
