Yes we are experiencing a lot of interference from powerline
adapters,and there is no authority here on the Aland Islands that
can/could enforce the regulations concerning PLC via powerline.

We are though happy that all electrical and phone lines are buried in
the ground, and not carried in the air.

KW> Does anyone here have any experience with SW/HAM radio and powerline

According to the regulations concerning any PLC transfer, the
frequencies that cover ham bands and other important transmissions must
be notched out from the transmissions. That concerns also powerline
adapters, but trying to get the authorities to take action against them
is very difficult.

Once the PLC signals enter the house wiring they are of course radiating
their transmissions all over.


Have a nice day,

Holger
