4.6.1.3. Selecting the type of audio filters
Analog signals on SDR repeaters can be fltered on four modes. The
standard one is the de/pre-emphasized, but you also can select
other modes for some special application.
Press on the Audio Filters side arrow to slide down the menu.
Figure 56: Audio Filters selection for analog profiles
Flat: No filtering for RX or TX. The modulation audio is just the
discriminator signal (flat) from the receiver. This mode cannot be
used when the repeater integrates a network environment because
the audio exchanged to the IP or monitor should be emphasized.
De-Emphasis: Received signals are de-emphasized then modulated
in flat format.
Pre-Emphasized: Received signal is left flat and the TX modulation
on emphasized.
De/Pre-emphasized: Received signals are de-emphasized processed
on this condition then emphasized again for transmit. This mode is
the standard one.
