J13 LED
When transmitter is turned on, the computer will start in Power Set mode if there is a shunt in J13 (Power is set
last).
When you are tuning you will get better readings with the power all the way down (Power Adjust counter clock-
wise). Also it will help if the Cap Tune (10 turn device) is about in the middle of it’s range (5 turns in from either
way). Please note the tuning function is an alternative to using a meter.
To go to the Coil Tune program (first tuning step) turn transmitter on with shunt in J13, wait 1-2 seconds, remove
J13 shunt, then replace shunt back into J13. Please note you can preferably use a voltmeter.
To use the Coil Tune program
simply move the shunt on the
Coil Tune jumper block, and
then remove J13, if the voltage
is higher the LED will be green,
if lower the LED will be red.
Then immediately replace J13
shunt. At this point you can
move the Coil Tune shunt if
you wish again and take another
reading with J13. If the LED
goes blank (It is starting Cap
Tune program) just turn power
off/on with J13 in, then move
J13 out/in.
Be sure to have your hands
away from antenna and coil
areas when you remove J13 to
take a reading, otherwise you
may get confusing readings.
The goal in tuning is to peak the
voltage, or to arrive at the peak
possible voltage using the Coil
Tune shunt and tuning tool on
the Cap tune.
