volumeLR = volume for left and right channel
volumeC = volume for center channel
freq1..9 = frequency of all channels
### scopes
spectrum of input signal

spectrum of filtered input signal for single channel (first 6 channels)
spectrum of signal after FM demodulation (first 6 channels)
constellation after PSK decoder (first 6 channels)
### gain and loop_bw sliders
intermediate frequency-, baseband- and radio frequency gain of SDR hardware

loop_bw = loop bandwidth of all PSK decoders
