  18 "lf read"
  19 "data samples"
  20 "data pskdet"

  22 "data pskindala"
  23 "data psknrzraw"

  26         change the configuretion block 0 with:
  27     -xxxx8xxx = PSK RF/2 with Manchester modulation
  28     -xxxx1xxx = PSK RF/2 with PSK1 modulation (phase change when input changes)
  29     -xxxx2xxx = PSK RF/2 with PSk2 modulation (phase change on bitclk if input high)
  30     -xxxx3xxx = PSK RF/2 with PSk3 modulation (phase change on rising edge of input)
