DSL interferes with shortwave? Good to know. Now I won't get DSL,
but will stick with a cable modem, with its shielded cable.

I thought that the twisted pairs of phone lines would prevent most
signal leakage.
It does, the problem is that when you can easily detect microvolts, it
isn't hard for a twisted pair that is carring volts to radiate enough
energy to be detecatable at the microvolt level.

How about 100 baseT ethernet over CAT-5e twisted pair cable? Anyone know
what frequency ranges the signals on these lines operate at?

Yes..you can bend it around the corner, make it go straight into another
room - it's hard to do it wrong. You just have to experiment with
different configurations, layouts and lengths. I have a loop of about 30
feet of wire running along the baseboard of my office. Not as effective
as the outdoor antennas, but fine for hearing the more powerful stations.
