As for me, I prefer to let the DSP do it all. <br>
Excellent audio, and less stuff to bring in and out of the radio. Fitting into a network of similar nodes you also maintain a consistency of sound. <br>
<br>
And with XIPAR you have the very nice working high and low pass filters. <br>
<br>
Meanwhile, some people have noted erratic operation of the DSP noise squelch on weak signals. <br>
<br>
On my frequency agile remote base (with a Syntor X) I was forced to use the squelch in the radio and USB input via a URI. That was due to different, or no PL on the various channels. But still using the DSP to de-emphasize, limit, and pre-emphasize. This works very well also. <br>
<br>
Experiment. Find which way you prefer. <br>
