TODAY.  THERE WAS AN ANTENNA CHANGEOVER RELAY, WITH A COUPLE OF ADDITIONAL
SETS OF CONTACTS THAT COULD ALSO CONTROL ANOTHER RELAY.  THE ANTENNA
CHANGEOVER RELAY SWITCHED THE ANTENNA FROM THE RECEIVER TO THE TRANSMITTER,
WHILE THE OTHER CONTACTS MUTED THE RECEIVER DURING TRANSMIT AND TURNED ON
THE VFO.  FOR SAFETY REASONS, IT WAS ALSO IMPORTANT TO GROUND EVERYTHING,
BECAUSE MOST 1950S ERA EQUIPMENT DID NOT HAVE POLARIZED AC PLUGS.  TUNING
THE GLOBE SCOUT TUNING THE RIG REQUIRED CARE AND ATTENTION.  THE PI NETWORK
OUTPUT CIRCUIT HAD A VERY WIDE RANGE, AND IT WOULD TUNE ALMOST ANY LOAD.
MOST RIGS DID NOT HAVE AN RF OUTPUT METER, YOU TUNED THE RIG BY DIPPING THE
FINAL PLATE CURRENT AND INCREASING THE LOADING UNTIL YOU ACHIEVED THE
DESIRED PLATE CURRENT WHILE MAINTAINING ACCEPTABLE GRID CURRENT.  ASSUMING
