| The T7F tranceiver module itself is controlled through
the serial interface and the build-in memory. For stationary operation this
is fine. However more comfortable is the LCD-user interface. The module includes
a two-line LC-display and a rotary resolver with integrated push button switch.
Depending on the rotation direction the microcontroller on the T7F board
translates the pulses from the resolver into frequency up or down information.
The mode (duplex, simplex, reverse) is selected with the push button. The
key S2 provides fast tuning with 500kHz steps. Beside status information
the lower line of the LCD shows a 12-step S-meter bar. |
