I think people are being silly.
Not only has there never been any evidence (beyond some fraudulent thing
that created hysteria) that power lines ever cause health problems, a dc
line has much less radiation.
As far as Ham radio, a dc is far less problematic for noise. 690 kV dc is
like 487 kV ac, except the line doesn't have the charging and discharging
issues that generate a lot of noise in bad connections.
The only possible issues would be noise at the dc-to-ac converters, but they
might be miles from you.
I wouldn't worry, and I would not support those who worry about other issues
like safety or health.
