SOLUTION, IT RECALLS THE STORED SOLUTION AND APPLIES THESE VALUES TO
THE CIRCUIT.  IMPRESSIONS I HAVE USED FLEXRADIO SYSTEMS EQUIPMENT
SINCE THE FLEX 6000 SERIES WAS INTRODUCED.  ALTHOUGH I HAVE NO
BUSINESS RELATIONSHIP WITH FLEXRADIO OTHER THAN BEING AN
ENTHUSIASTIC CUSTOMER, I HAVE BEEN A MEMBER OF FLEXRADIOS ALPHA TEST
TEAM FOR ALL OF THEIR PRODUCTS, INCLUDING THE TG XL.  ON THE OTHER
HAND, OWNING THE COMPLETE FLEX ECOSYSTEM IS ESSENTIAL TO OPERATING
THIS UNIT AT ITS THE DESKTOP APP YOU CAN SET UP, CONFIGURE, AND
OPERATE THE TG XL USING THE WINDOWS UTILITY APP PROVIDED WITH YOUR
TG XL SEE FIGURE 2.  THE DESKTOP APPLICATION BECOMES HANDY IT IS
AVAILABLE ANYWHERE YOU CAN CONNECT TO YOUR LAN.  I LIKE TO SIT ON MY
BACK PORCH AND OPERATE.  I CONNECT TO MY RADIO, AMPLIFIER, AND TUNER
WITH A LAPTOP COMPUTER, USING MY HOME NETWORK WI FI.  THE TG XL CAN
OPERATE FULLY AUTOMATICALLY, OR YOU CAN MANUALLY TUNE IT.  METERS
SHOW THE OUTPUT POWER AND SWR FOR RADIO A 1 AND RADIO B 2 WHEN
TRANSMITTING ON EITHER.  WHEN TRANSMITTING, THE PTT BLOCK LIGHT
SHOWS WHICH ONE IS TRANSMITTING.  THE BLUE CIRCLES SHOW THE POSITION
OF THE TG XL COMPONENTS AND CAN BE USED TO MANUALLY ADJUST THEM.
NEXT TO THE COMPONENT CONTROLS YOU WILL SEE THE STBY, BYP, AND TUNE
BUTTONS.  THE STBY BUTTON PUTS THE TG XL IN STANDBY.  THE BYP BUTTON
BYPASSES THE TUNER AND ALLOWS YOU TO MEASURE THE NATIVE SWR OF YOUR
ANTENNA SYSTEM.  CLICKING ON THE TUNE BUTTON WILL CAUSE THE TG XL TO
TUNE.  CAUTION IF YOU ARE NOT OPERATING IN THE FLEX ECOSYSTEM,
REMEMBER TO PUT YOUR AMPLIFIER IN STANDBY AND SET YOUR TRANSCEIVER
FOR LOW POWER 20 W RECOMMENDED BEFORE TUNING.  CIRCUIT DESCRIPTION
FROM A HIGH LEVEL VIEW, THE TG XL CIRCUIT SHOWN IN FIGURE 3 LOOKS
JUST LIKE ANY PI NETWORK ANTENNA TUNER.  THE TWO CAPACITORS AND THE
VARIABLE INDUCTOR ACTUALLY ARE A LARGE NUMBER OF INDIVIDUAL
COMPONENTS THAT ARE CONTROLLED BY A MICROCONTROLLER.  AND THATS
WHERE THE MAGIC HAPPENS.  THE MICROCONTROLLER DETERMINES THE
COMBINATION OF THE LC COMPONENTS THAT BEST MATCHES THE ANTENNA
SYSTEM TO THE TRANSMITTER.  THERE ARE 16,581,375 POSSIBLE MATCHING
COMBINATIONS.  THE FIRST TIME YOU TUNE THE TG XL TO A NEW FREQUENCY,
IT WILL TUNE IN 2 12 SECONDS AND STORE THE SETTINGS IN MEMORY.  THE
NEXT TIME IT WILL RECALL THE SETTINGS FROM MEMORY AND TUNE IN LESS
THAN 20 MILLISECONDS.  SETUP YOU CAN SET UP THE TG XL USING THE
SCREEN ON ITS FRONT PANEL OR USING THE DESKTOP APP WINDOWS UTILITY
PROGRAM.  I FIND IT MUCH EASIER TO USE THE DESKTOP APP.  YOU NEED TO
CONFIGURE THE TG XL TO WORK WITH YOUR TRANSCEIVER OR TRANSCEIVERS
THAT WILL DRIVE IT.  WHEN YOU START THE DESKTOP APP, IT WILL
AUTOMATICALLY DISCOVER YOUR TG XL IF YOU ARE ON YOUR LAN.  ONCE YOU
CONNECT TO THE TG XL, YOU CAN CONFIGURE THE TUNER.  CLICKING ON THE
GEAR ICON IN THE UPPER RIGHT HAND SIDE OF THE DESKTOP APP OPENS THE
TUNER GENIUS CONFIGURATION WINDOW SEE FIGURE 4.  THERE ARE FIVE
TABS.  THE FIRST ALLOWS YOU TO GIVE YOUR TG XL A UNIQUE NAME AND SET
UP YOUR NETWORK.  THE SECOND TAB, CAT / CI V, IS USED TO ENABLE A
CAT OR CI V
