[App_rpt-users] USB Radio Commands

[Jim W7RY]

I changed duplex=0 to duplex=1 in usbradio.cfg

That seemed to clean up the audio. Turning on the DSP, must make the audio slightly more bassy. 


Thanks all

I reconstructed the following query, as the answer to your question was already in the text you pasted.

Kevin


  So if this setting txprelim=yes   is: 

  TX audio processing. Options: (no,yes).

  Choosing yes turns on transmitter preemphasis and peak limiting, along with a lowpass filter. The yes option is used when driving an FM transmitter directly by injecting audio right into
  the modulator.

  -------------------------------------------

  What is the setting?
  txlimonly=no

  The no option provides audio which should be injected into the microphone input of the transmitter or at some point in the transmitter' speech amplifier before preemphasis, and limiting.
