Manual Inductor/Capacitor Adjustments
In some rare cases, after tuning, it may be desirable to adjust the inductance and capacitance
settings that the AT-100ProII came up with during the tuning process. This is more likely to
occur when attempting to tune an antenna far from its resonant frequency.
The
C Up, C Dn, L Up,
and
L Dn
buttons may be used to increment or decrement the
amount of capacitance or inductance, respectively. A momentary press of any of these buttons
increments or decrements the value by one unit, and displays the resulting value on the bargraph
meter. Capacitance value is displayed on the PWR bargraph, and inductance on the SWR
bargraph. These values are displayed in binary, left justified. The lowest-order relay is displayed
on the leftmost LED. The rightmost LED on the PWR bargraph displays the state of the
High/Low Impedance relay.
Repeatedly press one of these buttons to increment or decrement multiple times, or simply
hold the button and the button will auto-repeat. You may also transmit while incrementing or
decrementing, so that the SWR value is displayed, but the capacitor and inductor values will not
be displayed during transmit; instead, the power and SWR levels are displayed.
High/Low Impedance Relay Adjustment
In addition to being able to manually control the inductor and capacitor value of the AT-
100ProII, it is also possible to manually set the high/low impedance relay, which determines
whether the tuner is an L-C configuration or a C-L configuration. To toggle the state of the
high/low impedance relay, press
Func -> Ant
. The LED display will show one of two patterns to
confirm the setting.
Manual Memory Store
Once manual adjustments are complete, press
Func -> Tune
(that is, press
Func
momentarily, then
Tune
momentarily) to store the current relay settings in the memory
associated with the frequency last transmitted upon.
Status Check
The status of most user settings can be checked by pushing and
holding
the
Func
button
while pressing the relevant button for that setting. For example, to check to see what the current
