CHANGING THE TELEX AGC CHARACTERISTICS
The TLX AGC controls the radio’s receiver gain when receiving TELEX mode
signals. The characteristics may be changed to one of two settings labeled
“FAST” and “SLOW”. The “FAST” setting uses feedforward AGC.
Feedforward AGC is an aggressive AGC system that is very noise immune and
keeps the audio level fairly constant for received signals of different strength.
Some forms of TELEX such as “CLOVER” requires a “SLOW” setting to
properly receive the signal. Refer to the data provided by the specific MODEM
manufacturer.
Repeatedly press until “SETUP” is
displayed.
Pressing with “SETUP” displayed
will prompt the operator to “PRESS+-”.
Press the or key until “TLX AGC” is
displayed then press
Each press of the or key will change
the TLX AGC characteristics. Press
to select the displayed setting.
Use a setting of “FAST” (default) for better
signal to noise ratio on weaker signals.
Use a setting of “SLOW” for a more complex
TELEX modulation method.
When “EXIT” is selected, the setting will not
be changed.
