ERT moved its streams from ert-live.siliconweb.com to
ert-ucdn.broadpeak-aas.com. ERT News still runs on the new host, so it is
repointed rather than removed.
The other five answered 404 on three separate attempts, and I could not
find a working replacement for any of them. Removing the only radio
channel left that section empty, so the heading goes with it.
Channels that merely refused the connection are left alone, since that is
what a channel served only inside Greece looks like from outside it.
