With this control, you can automatically seek for a busy channel.

11. [ESP] ESP 2-Noisekiller
The ESP 2 is fulfilling two functions at the same time.
In the first function the ESP 2 reduces the annoying noise and cracking with the receipt of very weak
signals. The second function begins if a stronger signal is received. Here the ESP 2 switches on
automatically an active bandpass filter which suppresses a still existing noise and cracking. Thus
the voice/modulation will be emphasised clearly from the background noises.
