Joystick Control
Frequency tuning and some other functions can be carried out with a PC games joystick or a
home made one. Joystick control is supported by the Monitoring module which must be
opened. TRX-Manager will use the default joystick configuration on a sound card or USB port.
Activation and functions
Setting the Joystick is done from the Joystick tab of the Preferences/Transceiver. Once
Joystick control has been enabled, each axis of the Joystick must be enabled and calibrated
separately. If one axis is not detected, TRX-Manager automatically disables it in order to
avoid an inopportune frequency drift.
Please note, if TRX-Manager is configured in SERVER mode (see Remote control), the Joystick
does not have any effect.
X-Y Axis (ailerons and elevator)
These axes tune the frequencies by the step generated by the program. The step is variable
according to the position of the Joystick. X-Axis variably scans while Y-Axis increases or to
decreases the effect of the variable scanning. In order to understand how the tuning step is
calculated, you may observe the step displayed by the program according to the position of
the X-Y Axis.
R-Axis (rudders)
This axis controls the frequencies in two ways: by default, R-Axis has the same effect than
X-Axis but the step may be different. If Internal Tuning is checked, the step is fixed and is
determined by the scanning function of the transceiver. This give more precise tuning but this
option may not run with all transceivers. It is especially recommended in remote control mode.
If this function is not available, TRX-Manager displays N/A in the monitoring window.
Z-Axis (throttle)
This axis controls the AF gain (if available).
Calibrating
The joystick must be calibrated. For each axis, apply the joystick fully in each direction and
press the corresponding Cal. button. Now, center the action of the Joystick while pressing
the Center button.
The backlash of the Joystick (or neutral zone) may be adjusted for each axis separately.
Please increase the value of the backlash (the value has no dimension) if you note a frequent
frequency drift.
Lastly, scanning steps are fully configurable for each axis.
