I recall working with a former Denver Center controller nearly twenty

I've experienced that very situation also, in Denver and ABQ airspace. It
got so confusing one time, that the controller had to make a broadcast to
explain it to all us VFR flight following types, that he had multiple
transmitters on the same frequency, and not to worry if you don't hear
every transmission. What I've always wondered, is why do they bother? Are
they just trying to save a little electricity? It seems like this switching
of transmitters on and off is just extra workload for them with no
particular advantage. No one else is using the frequency in that area
except him. What am I missing?
