No, this is high power stuff.  A 5000W transmitter into 50 ohms is 500V,
enough to kill you.  This is done in an interlocked cabinet with large
knobs that have numeric indicators so you can record your settings.  At
least this is how it was done in the 60's.  The inductors/capacitors are
big to handle the voltages.

Maybe it is computer controlled in this day and age.  I don't really
know
