CONNECT AN ANTENNA ANALYZER AND A BIAS T, SWITCH THE NET WORK TO 160 METERS
AND SHORT OUT THE TOP TURNS OF THE COIL WITH A TEST LEAD UNTIL THE RESONANT
POINT OF THE MATCHING NETWORK IS AT YOUR PREFERRED FREQUENCY.  SOLDER THE
COIL CLIPS OF THE SHORTING WIRE IN PLACE.  NEXT, SWITCH THE NETWORK TO 80
METERS, AND FIND THE CORRECT POINT TO ATTACH THE 80 METER OUTPUT LEAD.
SOLDER ITS COIL CLIP TO THE COIL.  ON 160 METERS, THE NETWORK WILL LOWER
THE SWR OVER A NARROW FREQUENCY RANGE TO THE POINT THAT YOUR SHACK TUNER

CAN MATCH THE ANTENNA.  THE 80 METER SWR IS REASONABLY LOW ACROSS THE WHOLE
BAND.  OPERATING  THE 12 V DC SOURCE, CAPABLE OF 600 MA, MUST BE ISOLATED
FROM YOUR RADIO POWER SUPPLY.  I CAN RUN ABOUT 900 W INTO THE MATCHING
NETWORK ON 160 METERS BEFORE THE GDT FIRES TO PROTECT THE RELAYS.  I EARNED
160 METER DXCC IN LESS THAN A WINTER SEASON.  MANY THANKS TO PHIL, AD5X,
FOR ALL HIS HELP IN MAKING THE NEW DESIGN HAPPEN.  ARRL LIFE MEMBER STEVE
