Here in Dallas, KERA (90.1 FM) carries the BBC feed from local midnight
until morning when "All Things Considered" comes on.

Even if the "Beeb" has a somewhat liberal slant, its much better
listening than Art Bell's show, which seems to be carried by nearly
every AM station in the country trying to find something to drive its
tubes with during the middle of the night.

Tubes?


I was under the impression that most commercial transmitters used tubes.
I don't think a couple of 2n2222 transistors could handle a 50 KW output.

The only stations that still use tubes for AM are the poorer ones.
