Check the ARRL website for info about arc-fault interrupters. Some are
known to have RFI issues.
You may be setting them off simply because the TX antenna is closer to
their wiring, or because there's an issue with the counterpoise for that
antenna.
As to the computer issues -- some computers are better/worse than others
with respect to RFI. RFI is coupled both on internal wiring due to poor
circuit layout and inadequate shielding, and also on external wiring due
to poor circuit design practices inside equipment like "The Pin One
Problem." RFI pickup on external wiring can be reduced by the use of
suitable common mode chokes. RFI pickup on internal wiring usually
cannot be fixed -- the product must be replaced.
This tutorial on killing receive noise includes specific winding
recommendations for ferrite chokes that kill RF current on small
diameter cables. While the tutorial is written for RX noise in our
radios, the chokes do the same thing for current induced in those cables
by our transmitters. In essence, the cables are acting as antennas --
they transmit the noise FROM the noise source, and they receive the RF
that we transmit and couple it to the poorly designed product.
