- Note: When measuring sensitivity using SINAD, it is very important that the Audio Filter is enabled and the cut-off frequencies (and for FM measurements, also the de-emphasis) are set according to the specified test conditions. Proper audio filtering ...

The same applies to the audio Filter, Attenuator, Preamp and DDC settings.
If enabled, their settings will be stored together with the frequency and the
specified values will be applied when the memory is recalled.
Hotkey
For quick tuning to your favorite stations, you can also assign a Hotkey
(function keys F2 to F12) to up to eleven different frequencies. If you then
press this hotkey, the associated frequency will be instantly recalled. Hotkeys
which are already assigned will be shown in the drop-down list preceded with
an asterisk. However you can overwrite the previous assignment with a new
one if you wish.
Memory scan lockout
This setting relates to the Scanner facility. If this checkbox is ticked, this will
cause this frequency to be skipped while scanning.
Recalling a Frequency from Memory
There are several ways to recall a frequency from memory:
• Using the Recall button
• Using the Memory step buttons
• Using a hotkey
• Selecting the frequency directly from the memory tree structure
To recall a frequency, click on the Recall button. A dialog box will pop up
showing a list of all memory frequencies:
