STARTED WITH THE FULL SIZE TOWER PC IN USE AT MY STATION FOR MANY YEARS.
THERE WAS NO DETECTABLE INTERFERENCE EVEN THOUGH THE RADIOS, CABLING AND
COAX WERE CLOSE TO ONE ANOTHER.  I WAS OPERATING ON 80, 40 AND 20 METERS
AND NOTICED THE NOISE FLOOR WAS MUCH HIG

HINTS KINKS COUNTING TURNS ON VERY SMALL TOROIDS MADE EASY.  I WAS FACED
WITH THIS TASK WHILE BUILDING A FIREFLY 30 METER SOFTWARE DEFINED RADIO KIT
WWW. QRPKITS. COM/ FIREFLY. HTML.  I TRIED TO COUNT THE 56 TURNS ON A 3/8
INCH DIAMETER TOROID USING A MAGNIFYING BENCH LIGHT.  I COULDNT GET AN
ACCURATE COUNT.  I DECIDED TO TAKE A PICTURE OF THE COIL USING THE MACRO
MODE OF MY DIGITAL CAMERA.  I PRINTED IT OUT AND WAS ABLE TO EASILY AND
ACCURATELY COUNT THE NUMBER OF TURNS ON THE MUCH ENLARGED TOROID PICTURE
SEE FIGURE 1.  ALSO, I WAS ABLE TO KEEP TRACK OF MY PLACE WITH A PENCIL
MARK.  FIGURE 2 SHOWS 57 TURNS, I REMOVED THE EXTRA TURN.  SOLDERING RG 8X
TO A PL 259 I AM A WIRE ANTENNA EXPERIMENTER.  TUNING ANTENNAS THAT ARE IN
TREES CAN BE A CHALLENGE.  AT FIRST, I WAS USING THE FOUR HOLE SOLDER
METHOD FOR ASSEMBLING THE PL 259 CONNECTOR.  I WAS ALWAYS FIGHTING BROKEN
CABLE SLEEVE CONNECTIONS WHICH CAN EVEN GET YOU GOING ON A TRIMMING WILD
GOOSE CHASE.  THEN I REMEMBERED THE METHOD I USED AS A NOVICE.  LETS CALL
