VHF UP POSITIONS BY ROUTING 5 V TO THE INTERNAL UPCONVERTER WHEN SWITCHED
TO HF.  THE PWR LED GLOWS GREEN WHEN POWER IS SUPPLIED TO THE OSCILLATOR.
POWER INPUT FOR THE UPCONVERTER CONNECTS TO THE FRONT PANEL JACK, AND IS
SUPPLIED BY A WALL PLUG MODULE PRODUCING 9 TO 12 V DC AT 500 MA.  THE REAR
VIEW, SEEN IN FIGURE 4, SHOWS THE USB CONNECTOR ON LEFT, THE 1 KHZ 30 MHZ
ANTENNA CONNECTOR L, AND THE ABOVE 30 MHZ ANTENNA CONNECTOR H ON RIGHT.  I
BUILT MY PROTOTYPE UPCONVERTER ON HIGH QUALITY VECTOR BOARD.  THIS ALLOWED
FOR SOME TRIAL AND ERROR IN OPTIMIZING THE DESIGN.  VECTOR BOARD LIMITS
LAYOUT OPTIONS TO SOME EXTENT, BUT THERE IS PLENTY OF ROOM.  I USED AN SRA
1 DOUBLE BALANCED MIXER FROM MINI CIRCUITS AND A PRE PACKAGED 100 MHZ
CRYSTAL OSCILLATOR.  THERE ARE MANY DIFFERENT OSCILLATORS AVAILABLE.
