ELECRAFT K4 - AF Limiter (AGC off); AGC Settings

98
IV. MENU LISTING
The K4 configuration menu has one level (i.e., it is "flat"). Menu
settings are infrequently changed, and most can be left at their factory
default values.
Using the Menu
• Tap <MENU>. Use VFO or the up/down arrow keys to find the
desired entry.
• Most menu entries are locked to avoid inadvertent editing. To
unlock, tap the lock symbol.
• To edit, tap the parameter field. Tap the menu entry name field to
resume scrolling.
• When <NORM> is illuminated, the menu parameter is at its factory-
default value. If not, tapping <NORM> will set it to that value.
• Up to four menu entries can be assigned to programmable function
switches [PF1] through [PF4]. For details, see PF1-PF4. Menu entries
may be accessed using other user-programmable switches as well;
see MACRO PROGRAMMING.
Menu Entries (Alphanumeric Order)
AF Limiter (AGC off)
Sets the AGC-off audio limiter threshold. A higher value allows higher
audio volume prior to limiting. If the value is too low, receiver audio
will limit too soon.
AGC Attack
Sets the AGC attack rate. A value that is too small will allow excessive
overshoot on strong CW signals. A large value will make the attack
more abrupt.
