[BC] Any manned transmitter sites left?

[nakayle@gmail.com]

 For years the FCC required a licensed operator on duty at a transmitter
whenever it was on the air.  For stations with remote located transmitters
this meant maintaining a full staff of engineers at the transmitter site.
Over the years this requirement was eased and finally eliminated all
together, but as late the 1970s many large stations still maintained fully
staffed transmitter sites even after remote control was permitted.

Today things have changed dramatically and instead of having a staff of
engineers to maintain a transmitter you are more likely to find one lone
engineer charged with maintaining several different transmitter sites.

I'm curious if there are any stations today that still have manned
transmitter sites or is this truly a relic of a bygone era?
