The ESP (Electronic Speech Processor) is an exclusive advanced feature in some of

the new INTEK mobile CB radios. ESP means Electronic Speech Processor, in other

words electronic modulation processor. This microprocessor controlled audio device

is also called COMPANDER (Compressor-Expander), it works as a modulation

compressor in transmission and as a modulation expander is receive mode. The ESP

allows to obtain a stronger, cleaner and clearer audio signal and it is a great help in

noisy areas, in case of long distance communication or with weak signals. The

efficiency of ESP is even greater when communicating with other radios having the

same system. To enable or disable the ESP function, press the ESP key. When the

ESP function is enabled, the ESP icon (F) appears on the LCD display.
