of the shortwave and longwave frequencies. But I am considering a
wireless alternative to my slow dial-up for internet connectivity.
The system is based around this device:

The wireless ISP rep indicated that the power over ethernet line had
resulted in intereference for some local HAM users, and suggested a
shielded cable and/or selective routing may solve the problem.

I've not heard of any problems with power-over-ethernet causing
interference to hams. (that said, this is the first I've heard of
power-over-ethernet period!)

I think he may have had it confused with the opposite system,
broadband-over-power-lines (BPL) which DOES cause severe shortwave
interference.

I suppose there is some possibility that the provided 12v DC power unit
is not adequately filtered and that it radiates interference. I would
think a ferrite choke core (available at Radio Shack), placed as close
to the power unit as possible, would probably take care of the
interference. You *might* need another one at the wireless box itself.

But I wouldn't be all that worried about it.
