 TX control you can adjust the settings of the
transmitter: You can set some filters (low pass, high pass and notch), set a delay, choose to equalize the signal
to transmit (choosing the number of equalizer filter taps) and choose the modulation type (PM or FM).
HP filter
It is a programmable high pass filter that can be inserted at the transmitter. It is used to
eliminate the received sub-audio.
LP filter
It is a programmable low pass filter that can be inserted at the transmitter. It is rarely used
to limit the bandwidth of the receiver output.
Notch
The notch filter, if enabled, is automatically set on the frequency of sub-audio tone
transmission. It may be useful for reducing the phase distortion in simulcast networks with
a sub-master (it is factory set for a given application).
